it would show you the last selected shape key until doing
another operation. This is confusing, and the Pin button allows
you to do the same kind of shape browsing.
* Converted Drivers UI to mostly use the Layout Engine
* All the buttons that perform actions are not operators yet (the code for that would be quite icky still)
* I've added some (commented out) calls for the property definitions of Driver properties to perform Depsgraph updates. I've left these commented out until we have the option to turn off auto-updates, since with driver editing, that could be very dangerous.
* Drivers can now (in theory) use any ID-block, using the Any-ID template added earlier. However, be warned that the stupid depsgraph won't be able to cope with most of these cases.
TODO:
- more fancy widgets for RNA-Path and Index will come later
* Summary channel now works in DopeSheet AND Action Editors
* By clicking on the expand/collapse widget on the summary channel, you can now show/hide all the other channels in the editor.
Added new template for choosing to use any type of ID-block. The first combo box allows you to choose the type of ID-block that gets used, and the second box allows you to choose the ID-block of the type specified by the first one.
This is currently used for setting the ID-block used for Keying Sets, but the main user for this was intended to be the Drivers UI. However, I still need to clear up a few button-event issues there before I can port this over.
Additional Bugfixes:
* Adding new Keying Set path was setting the active path wrong, meaning that you had to click on the list to get some response after adding
* Bone Groups list was being drawn too long by default (when empty)
- Shift+F2 was Export DXF, made Logic Editor
- Shift+F4 was data browser, made console
- Shift+F11 was fullscreen in 2.5, changed fullscreen to Alt+F11
added Area.type so RNA can switch the type.
wm.context_set(path="scene.tool_settings.someattr", somevalue)
wm.context_toggle(path="scene.tool_settings.somebool")
wm.context_toggle_values(path="scene.tool_settings.some_enum", value_1="somevalue", value_2="othervalue") # switch between 2 values
wm.context_cycle_enum(path="scene.tool_settings.some_enum", reverse=False)
the path value is taken from the context so the full path is
context.scene.tool_settings...
This means in keymaps you can cycle draw modes, change PET- anything with rna access.
If its not so nice to map keys to operators like wm.context_set we could use macro's to wrap it and have its own name
Use this for PET and setting pivot options
- Made userpref key shortcut Ctrl+Alt+U since its not used in 2.4x
- added pivot_point_align (Alt+Comma)
- added PET wasnt rna wrapped correctly.
I noticed that armature drawing seemed to be using the wrong colours for ghosting in some situations (in particular, Cessen's biped rig for 2.5). Commented out what appears to be the offending code for now.
Not totally sure why this broke yet, but as possible bonus of this, we sometimes get coloured ghosted controls (if bone groups were in use).
The filtering buttons for datatypes will now only be shown if there is data of that type present in the current file. They will still be shown in the same order, but by hiding the ones that won't be of any relevance, the presentation of the views should be cleaner (I hope ;)
Added a summary channel that appears as the first channel in the DopeSheet. For now, this is disabled by default, but can be enabled using the 'Summary' toggle in the header between the mode selector and the standard filtering options. This has been done, since there is a possibility that it will make the DopeSheet run a bit slower.
In this channel you can do everything that you can normally do with DopeSheet channels (i.e. select, transform, edit, etc). It might be worth noting though that care probably needs to be taken when trying to use Copy/Paste, since that is still a bit fidgety...
In the process, I've fixed a few bugs, mostly with selection:
- Selecting keyframes in scene summaries wouldn't work
- Border select only worked in F-Curve and Group channels
* Reverting some changes I made to try and get Action Groups with no viewable F-Curves, but were collapsed to get hidden. These were causing buggy behaviour
* Move bones to armature layers, and change armature layer operators now use the new automatic properties drawing invoke callback. This allows changing the buttons there immediately affect the bones in the viewport
* #19581: Text Editor: "Jump To" (go to line) not working
Made this use the automatic operator props invoke callback, and fixed an RNA properties bug for this (the default value and range values were swapped).
* PoseLib rename pose operator now works again. Once again, this uses the auto-props popup. Also, improved the code here while I was at it.
* Disabled non-functional/old entry in Select Linked operator ("IPO's")
This is similar to the old retopo all option but uses the snapping code and not the openGL depth buffer (it's thus more precise).
Not sure if making it available as a snap option is sensible, this is up for discussion.
NOTE: it will get slow fast on large meshes, we need to plug in an acceleration structure into snapping.
This will need an icon too.
Since the deep shadow buffer summer of code project is not actively under
development anymore, I decided to build my own DSM implementation from
scratch, based on reusing as much existing shadow buffer code as possible.
It's not very advanced, but implements the basic algorithm. Just enough so
we can do shading tests with it, optimizations and other improvements can
be done later.
Supported:
* Classical shadow buffer options: filter, soft, bias, ..
* Multiple sample buffers, merged into one.
* Halfway trick to support lower bias.
* Compression with user defined threshold.
* Non-textured alpha transparency, using Casting Alpha value.
* Strand render.
Not Supported:
* Tiling disk cache, so can use a lot of memory.
* Per part rendering for lower memory usage during creation.
* Colored shadow.
* Textured color/alpha shadow.
* Mipmaps for faster filtering.
* Volume shadows.
Usage Hints:
* Use sample buffers + smaller size rather than large size.
* For example 512 size x 9 sample buffers instead of 2048 x 1.
* Compression threshold 0.05 works, but is on the conservative side.
eg.
for v in me.verts: print(v.index)
added calc_edges as an option eg.
mesh.update(calc_edges=True)
This is needed when adding faces to an existing mesh which create new edges.
changed extrude, rip and duplicate to disable proportional editing however this gives a different problem now.
Commented in transform.c
// XXX If modal, save settings back in scene
this changes disables the option whenever the macro used used.
* Only F-Curves and Drivers that affect selected bones will be visible when this happens.
* Moved the function to grab text within a pair of "" following some prefix to blenlib.
Deal with this by adding ED_view3d_init_mats_rv3d(ob, r3d) which initialized the region mat's and is used in mesh_foreachScreenVert, mesh_foreachScreenEdge etc.
bpy.ops.mesh.primitive_torus_add(major_radius=1, minor_radius=0.25, major_segments=48, minor_segments=16)
- experemental dynamic menus, used for INFO_MT_file, INFO_MT_file_import, INFO_MT_file_export and INFO_MT_mesh_add. these can have items added from python.
eg.
- removed OBJECT_OT_mesh_add, use the python add menu instead.
- made mesh primitive ops - MESH_OT_primitive_plane_add, ...cube_add, etc. work in object mode.
- RNA scene.active_object wrapped
- bugfix [#19466] 2.5: Tweak menu only available for mesh objects added within Edit Mode
ED_object_exit_editmode was always doing an undo push, made this optional using the existing flag - EM_DO_UNDO, called everywhere except when adding primitives.
It will check if either the operator or operator type flags are set on top of the user preference before grabbing the pointer.
I've set that flag for 3d view navigation operators, others should be set too (no transform, I'll deal with that one).
- removed custom invoke function, use generic names (was misleading since conversion is done on selection, not just active).
- made convert mesh to curve use the 'keep_original' option.
again. The saved image would still point to the render buffer,
which was freed again on render. This is not a real solution but
avoids the crash for now.
* Fix crash trying to enter particle mode when the particle modifier
is disabled in the stack.
* Fix redraw being very slow due to the draw function causing the
object to be recalculated on each redraw (through PE_draw_object).
* Removed the system where PE_get_current would automatically create
the particle edit, this would run from poll() functions, which gave
all kinds of issues, now it only creates the data on enter/exit
and switching active particle system.
In Animation Editors, F-Curves for Pose Channel Constraints now include the Pose Channel and Constraint names in the 'owner' part of the name displayed, making it easier to identify which Pose Channel some constraint F-Curve belonged to.
e.g. The influence setting for an IK Constraint on bone "Boney"
Old Version: Influence (IK)
New Version: Influence (Boney : IK)
We can experiment with different representations of this later (maybe '>' instead of ':' ?)
belongs here still, but this came up often, it avoids having to
switch tabs a lot when creating things.
Also renamed uiLayoutFreeBlock to uiLayoutAbsoluteBlock.
* #19583: Keying Sets list issues
Deleting a Keying Set (or a Keying Set Path) set the active index to 0, but that would mean that the first item would be selected but not visible.
* #19590: Keyframing properties of a modifier with more than one of it's type the property will highlight in all
- Modifiers now always have a unique name, so renaming a modifier should check that the name is unique. Most of the files changed in this commit were just to make sure that modifiers got unique names when they were created
- Modifiers path getter was wrapped a bit wrong (missing the "s around the name)
* Constraints Bugs
- Constraints renaming now also makes sure the names stay unique
- Fixed (or attempted to fix) compiler warnings about some enum declaration for distance constraint
BRECHT, CHECK THIS
The change made it return RNA python properties with null data pointer instead of None.
That would make the particles and physics properties crash like this:
1. A valid property instead of None makes is seem like smoke (or other) modifier data is in context when it is Null.
2. UI code would try to access RNA properties of the (Null) modifier, which would crash
Keymaps are now saveable and configurable from the user preferences, note
that editing one item in a keymap means the whole keymap is now defined by
the user and will not be updated by Blender, an option for syncing might be
added later. The outliner interface is still there, but I will probably
remove it.
There's actually 3 levels now:
* Default builtin key configuration.
* Key configuration loaded from .py file, for configs like Blender 2.4x
or other 3D applications.
* Keymaps edited by the user and saved in .B.blend. These can be saved
to .py files as well to make creating distributable configurations
easier.
Also, user preferences sections were reorganized a bit, now there is:
Interface, Editing, Input, Files and System.
Implementation notes:
* wmKeyConfig was added which represents a key configuration containing
keymaps.
* wmKeymapItem was renamed to wmKeyMapItem for consistency with wmKeyMap.
* Modal maps are not wrapped yet.
* User preferences DNA file reading did not support newdataadr() yet,
added this now for reading keymaps.
* Key configuration related settings are now RNA wrapped.
* is_property_set and is_property_hidden python methods were added.
* Loading old files didn't initialise the new rotation variables properly
* Fixed some errors with the newly added operator for copying RNA-paths for properties
* Auto-keyframing now correctly refreshes animation editors after adding keyframes. Made the keyingsets code send notifiers again, but now using the newly added WM_main_event_add() (thanks Brecht)
* A few UI tweaks again for animation stuff (timeline, keyingsets UI)
- editing properties from python wasnt running their update function.
- missing commas made dir(context) give joined strings.
- added __undo__ as an operator class attribute so python ops can be set as undoable. (like existing __register__)
* Added a new option for Auto-Keyframing which makes it only insert keyframes for the items included in the active Keying Set.
This only works for Transform Auto-Keyframing so far (other tools will get it added later). The option is disabled by default.
* Fixed bug where adding an 'entire' array to some KeyingSet would only start from the index of the button that the mouse was over at the time
* Made some UI tweaks for Keying Sets buttons (still heaps of missing options there).
The hardcoded paths for rotation keyframes on objects got broken by my commits to rename the rotation properties. I've taken this opportunity to recode the auto-keyframing code here to use the builtin keyingsets instead of going through and manually calling insert_keyframe(), thus preventing this problem in future.
* Removed the hack-functions to set euler rotations from the values set in the other rotation representations, even when euler rotations weren't being used. I pressume that this was added for being able to represent quats in terms of eulers for the UI, but really it would break animation evaluation (i.e. euler curves after quaternion curves would always block the quaternion curves).
* Object rotation values in the transform properties panel now take into account rotation modes, so the appropriate rotations will get converted to quaternions before being drawn.
* Fixed a few bugs with some of the conversion code (minor stuff left out).
Animating rotations using different rotation modes should now work more often than before.
Previously, quaternion and axis-angle values were stored in the same variable in DNA, but that was causing problems with other animation curves overwriting the values and causing the rotations to not work as expected.
There are still some issues, but I'll track those down later tonight
* Compo node backdrop works again.
* Compo node previews and backdrop now get correct color management
float to byte conversion.
* Compo nodes got unecessarily recalculated while moving nodes.
* Fix compo node viewer nodes not getting activated correctly.
* Main compo node preview render computations are now outside of
mutex lock, so better for multithreading.
* Tex node outputs did not work in some files loaded from 2.4.
* Change RNA updates to take into account groups that may be shared
between multiple node trees.
of the main reasons for passing along context, while actually
they don't need much context at all. Might be removed again,
but would like to have this especially for RNA API functions.
* Make Ctrl+M key work for mirror in 3D view.
* Fix mirror along global axis, was mirroring around all axes when
the object was rotated, due to wrong matrix order, was also not
working in 2.4.
* Pressing e.g. X twice still doesn't go to local mode, would fix
but don't know how the code is intended to work.
- added TexMesh access ([#19505] Missing option : TexMesh)
- Ctrl+Tab works again, not-so-nice workaround, disallow switching to paint modes from editmode, but would be nicer to manage this with keymaps.
- Useful for dragging buttons to the far right when theyd otherwise hit the screen edge.
- Useful for transform though probably NOT what you want when using the transform manipulator (should make an option).
- When enabled, number buttons use this as well as a different conversion of mouse movement
float numbuts: mouse 1px == 1-clickstep
int numbuts: 2px == 1 (tried 1:1 but its too jitter prone)
details...
- access as an option to GHOST_SetCursorGrab(grab, warp)
- Currently all operators that grab use this, could be made an operator flag
- only Ghost/X11 supported currently
The makefile is a copy of the source one, not tuned, just to unbreak build.
This raises some questions: why separate dirs? why each build system takes
a different approach (different libs vs all source files into one)?
(Mostly for very early testers)
Cocoa uses coordinates with y=0 at bottom : updated wm_window.c and wm_event_system.c for COCOA build to avoid double conversions in response to mouse move events and GHOST_getCursorPosition
Known limitations:
No fullscreen support
Font issue in preference panel
libSDL uses some Carbon functions
Selecting a material in the node tree sets this as the active material and the buttons view redraws.
Added rna prop material.active_node_material
Currently its not clear what settings are used by the node material and the base material (needs some tedious research) so I made most panels use the node material with the exceptions of volumetrics, physics and halo settings.
We'll probably need to split the panels up to do this properly.
This calls a registered menu as a popup so we can reuse header menus , currently used for Node editor and Sequencer add menu (Shift+A), can be used for toolbox too.
In the Outliner, it is now possible to toggle per bone the selectability of the bone in the viewport, as for Objects using the restriction columns. This can also be set using the RNA-api.
I've tested all commonly used tools IMO, but there may still be a few which I've missed. Please report those cases.
PS. For some reason, the define was already there, but not connected up to anything. Can't remember why anymore, but here it is...
*Disabled ray counter (can be enabled on render/extern/include/RE_raytrace.h by commenting out the define)
*marked bvh_node_merge() as static inline (hopping it now compiles on gcc and mingw)
* Made bvh_node_merge() in svbvh.h static (fix suggested by jaguarandi). This makes mingw link again.
* Also, patched my previous fix for ... = {}; since mingw didn't like the other fix (which was for msvc).
* Replaced ... = {}; with ... = {0};
* Solved problem with logf(), where msvc couldn't figure out which version of log() to call (solved by casting the int argument to a float, but could also have been to double)...
* The cflags and cxxflags for scons when compiling the rendering module were only valid for gcc compiles. These will still need to get added for msvc sometime, but for now, there are no more warnings about unknown options...
* mingw almost compiles again cleanly, except for a linking error when linking blender http://www.pasteall.org/8297
* win64 should compile again too to a similar degree?
* silenced warnings about no newlines...
* Code for generating 'Object' summary of Keyframes for DopeSheet (which is also used by the TimeLine for getting keyframes to draw) now considers materials, object data, and particles too.
* Rearranged the way that keyframing-related settings were presented in the User Preferences. The way the settings were grouped was plain confusing, and based on biased views from the old system. For the record, 'needed'+'visual' are always considered when inserting keyframes, 'always' is for autokeyframing, and default interpolation is only used for newly created F-Curves.
* Fixed bug #19472 - Scroll wheel scrolls in the wrong direction for enum-menus that were flipped (i.e. window type menu and 3d-view mode selector).
* Disable use of EditMeshDerivedMesh for VBO drawing in editmode.
This is crashed when using e.g. subsurf in editmode, as the DM
is not an EditMeshDerivedMesh.
* Fix slowdown/freeze entering editmode on a high poly mesh,
dm->getNumFaces can be slow, don't call it in a loop.
* Fix 64bit pointer casting warnings.
The goodies:
* Curves can be used as normal dynamic effectors too with
the new "curve" field shape.
* Group visualization has optional duplication counts for
each object in the specified group.
* Object & group visualizations, which are done without
taking the dupliobject's global position into account
(unless the whole group is used). This is much nicer than
the previous behavior, but I added a "Use Global Location"
option for those who want to use it the old way.
* The active particle system's particles are now drawn a
with theme coloured outline instead of pure white.
* Added object aligned velocity factors (buttons categorized
and re-organized too).
Bug fixes:
* Absorption didn't work as the ui toggle button was forgotten.
* Some other force field ui tweaks.
* Crash after adding children and changing trails count.
* Display types "cross" and "axis" crashed.
* Particles weren't drawn with correct coloring.
* Billboards didn't update properly in viewport to camera
location changes.
* Particle rotation wasn't recreated correctly from point cache.
* Changing particles amount crashed sometimes.
* Some files with child hair crashed on loading.
* Compiler warning fixes.
* Adding boids crashed on frame 1;
- Window creation at preferred size
Implement in Ghost the use of Cocoa functions to get the maximum visible rect (size and position) for the window contents (all screen excluding dock, top menu, and window title bar)
Thus Apple specific code in window creation (wm_window.c & wm_apple.c) is no more needed => removed in case of Cocoa build
- Alert on exiting despite unsaved changes
Add to GHOST method to maintain an all platforms (not apple specific anymore) status on unsaved changes
Update GHOST_SystemCocoa to use this for asking or not user to confirm exit without saving changes
Volumes can now receive shadows from external objects, either raytraced shadows or shadow maps.
To use external shadows, enable 'external shadows' in volume material 'lighting' panel. This an extra toggle since it causes a performance hit, but this can probably be revisited/optimised when the new raytrace accelerator is integrated. For shadow maps at least, it's still very quick.
Renamed 'scattering mode' to 'lighting mode' (a bit simpler to understand), and the options inside. Now there's:
- Shadeless
takes light contribution, but without shadowing or self-shading (fast)
good for fog-like volumes, such as mist, or underwater effects
- Shadowed (new)
takes light contribution with shadows, but no self-shading. (medium)
good for mist etc. with directional light sources
eg. http://vimeo.com/6901636
- Shaded
takes light contribution with internal/external shadows, and self shading (slower)
good for thicker/textured volumes like smoke
- Multiple scattering etc (still doesn't work properly, on the todo).
- terrible typo was making the multiplication to run in an infinite loop.
- Any matrix * vector multiplication would crash Blender.
eg
####
import Mathutils
from Mathutils import *
vec_ray = Vector(0.0, 0.0, 1.0)
tilt_mat = RotationMatrix(0.0, 3, "y")
vec_ray = tilt_mat * vec_ray
####
* #19529: Saving in edit mode causes problems in mode buttons when reopening
* Fixed compiler warning in writefile for mingw
* AnimData for Lamp data was not recognised by RNA
*Fixed some spacing issues in 3D View and Outliner headers
*Made the Bone properties layout consistent with Object properties
*Put Rotation Mode menus below transformation channels, being less important.
*Tiny layout tweak for area lamps
Added a way to view and edit Keying Sets via the Scene Buttons. These are still some tweaks needed to make this really workable, but should still work well enough for simply viewing and tweaking existing Keying Sets created using other means.
Additional bugfixes:
* Adjusted the size of labels on properties that had a 'label' for their name. Now it uses 1/3 of the total width instead, which looks much better for most cases.
* Added missing entries for adding Force Fields from the Info-header 'Add' menu. At some point we should unify this menu with the popup operator's one, since this is exactly the kind of situation we had hoped in avoid with new UI architectures.
* Moved all the operator defines for keyframing stuff to the 'intern' anim header instead
* Fix loading issue of blend files with smoke collision objects (was disabled on purpose since it will be subject of change, but can be solved using do_versions() later)
one active. Now there's a function to get the pointer + property from
the UI, just like for the animation operators.
Also two fixes for fileselect events, regions are now preserved so that
context is restored to the old region, and the cancel callback is called
when the operator is cancelled.
Since bli_threads.h now includes pthreads directly, we need to had instructions in SConscripts everywhere for proper include path.
Frankly, I feel like this should be done in a global manner and not in a per lib fashion, but that is for another day.
This commit also fixes more missing properties
So means minimum twist and twist smoothing are now used.
the Z up quaternion from the path is rotated to match the up axis given.
There was no logical rule for the up vector, some cases flipped the normals when used with the CurveDeform modifier.
Use the default X-Up behavior and match other settings with this. (comments explain this in detail).
- Interpolating quaternions didn't work in some cases, disabled for now.
- 'no_rot_axis' is different from in 2.4x since it now removes rotation from the tilt whereas before it edited the axis before calculating the tilt.
* Unified scene wide gravity (currently in scene buttons)
instead of each simulation having it's own gravity.
* Weight parameters for all effectors and an effector group
setting.
* Every effector can use noise.
* Most effectors have "shapes" point, plane, surface, every point.
- "Point" is most like the old effectors and uses the
effector location as the effector point.
- "Plane" uses the closest point on effectors local xy-plane
as the effector point.
- "Surface" uses the closest point on an effector object's
surface as the effector point.
- "Every Point" uses every point in a mesh effector object
as an effector point.
- The falloff is calculated from this point, so for example
with "surface" shape and "use only negative z axis" it's
possible to apply force only "inside" the effector object.
* Spherical effector is now renamed as "force" as it's no longer
just spherical.
* New effector parameter "flow", which makes the effector act as
surrounding air velocity, so the resulting force is
proportional to the velocity difference of the point and "air
velocity". For example a wind field with flow=1.0 results in
proper non-accelerating wind.
* New effector fields "turbulence", which creates nice random
flow paths, and "drag", which slows the points down.
* Much improved vortex field.
* Effectors can now effect particle rotation as well as location.
* Use full, or only positive/negative z-axis to apply force
(note. the z-axis is the surface normal in the case of
effector shape "surface")
* New "force field" submenu in add menu, which adds an empty
with the chosen effector (curve object for corve guides).
* Other dynamics should be quite easy to add to the effector
system too if wanted.
* "Unified" doesn't mean that force fields give the exact same results for
particles, softbody & cloth, since their final effect depends on many external
factors, like for example the surface area of the effected faces.
Code changes
* Subversion bump for correct handling of global gravity.
* Separate ui py file for common dynamics stuff.
* Particle settings updating is flushed with it's id through
DAG_id_flush_update(..).
Known issues
* Curve guides don't yet have all ui buttons in place, but they
should work none the less.
* Hair dynamics don't yet respect force fields.
Other changes
* Particle emission defaults now to frames 1-200 with life of 50
frames to fill the whole default timeline.
* Many particles drawing related crashes fixed.
* Sometimes particles didn't update on first frame properly.
* Hair with object/group visualization didn't work properly.
* Memory leaks with PointCacheID lists (Genscher, remember to
free pidlists after use :).
* Rendering twice or more could crash layer/pass buttons.
* Compositing would crash while drawing the image.
* Rendering animations could also crash drawing the image.
* Compositing could crash
* Starting to rendering while preview render / compo was
still running could crash.
* Exiting while rendering an animation would not abort the
renderer properly, making Blender seemingly freeze.
* Fixes theoretically possible issue with setting malloc
lock with nested threads.
* Drawing previews inside nodes could crash when those nodes
were being rendered at the same time.
There's more crashes, manipulating the scene data or undo can
still crash, this commit only focuses on making sure the image
buffer and render result access is thread safe.
Implementation:
* Rather than assuming the render result does not get freed
during render, which seems to be quite difficult to do given
that e.g. the compositor is allowed to change the size of
the buffer or output different passes, the render result is
now protected with a read/write mutex.
* The read/write mutex allows multiple readers (and pixel
writers) at the same time, but only allows one writer to
manipulate the data structure.
* Added BKE_image_acquire_ibuf/BKE_image_release_ibuf to access
images being rendered, cases where this is not needed (most
code) can still use BKE_image_get_ibuf.
* The job manager now allows only one rendering job at the same
time, rather than the G.rendering check which was not reliable.
* #19501: Only the first user of multi-user IPO's were getting converted to AnimData.
Now, this AnimData gets converted multiple times - once for each user. This will mean that multi-user actions will no longer be multi-user after conversion though, although this could be fixed manually if there really is such a need.
* #19503: Nasty memory leaks when duplicating objects with AnimData
Fixed a few little oversights made when coding the copying code for NLA-data (which resulted in exponential copying-loops of doom), and sanitised the AnimData copying code for ID-blocks to be simpler to manage.
After code review and experimentation, this commit makes some changes to the way that volumes are shaded. Previously, there were problems with the 'scattering' component, in that it wasn't physically correct - it didn't conserve energy and was just acting as a brightness multiplier. This has been changed to be more correct, so that as the light is scattered out of the volume, there is less remaining to penetrate through.
Since this behaviour is very similar to absorption but more useful, absorption has been removed and has been replaced by a 'transmission colour' - controlling the colour of light penetrating through the volume after it has been scattered/absorbed. As well as this, there's now 'reflection', a non-physically correct RGB multiplier for out-scattered light. This is handy for tweaking the overall colour of the volume, without having to worry about wavelength dependent absorption, and its effects on transmitted light. Now at least, even though there is the ability to tweak things non-physically, volume shading is physically based by default, and has a better combination of correctness and ease of use.
There's more detailed information and example images here:
http://wiki.blender.org/index.php/User:Broken/VolumeRendering
Also did some tweaks/optimisation:
* Removed shading step size (was a bit annoying, if it comes back, it will be in a different form)
* Removed phase function options, now just one asymmetry slider controls the range between back-scattering, isotropic scattering, and forward scattering. (note, more extreme values gives artifacts with light cache, will fix...)
* Disabled the extra 'bounce lights' from the preview render for volumes, speeds updates significantly
* Enabled voxeldata texture in preview render
* Fixed volume shadows (they were too dark, fixed by avoiding using the shadfac/AddAlphaLight stuff)
More revisions to come later...
Editors Modules
* render/ module added in editors, moved the preview render code there and
also shading related operators.
* physics/ module made more consistent with other modules. renaming files,
making a single physics_ops.c for operators and keymaps. Also move all
particle related operators here now.
* space_buttons/ now should have only operators relevant to the buttons
specificially.
Updates & Notifiers
* Material/Texture/World/Lamp can now be passed to DAG_id_flush_update,
which will go back to a callback in editors. Eventually these should
be in the depsgraph itself, but for now this gives a unified call for
doing updates.
* GLSL materials are now refreshed on changes. There's still various
cases missing,
* Preview icons now hook into this system, solving various update cases
that were missed before.
* Also fixes issue in my last commit, where some preview would not render,
problem is avoided in the new system.
Icon Rendering
* On systems with support for non-power of two textures, an OpenGL texture
is now used instead of glDrawPixels. This avoids problems with icons get
clipped on region borders. On my Linux desktop, this gives an 1.1x speedup,
and on my Mac laptop a 2.3x speedup overall in redrawing the full window,
with the default setup. The glDrawPixels implementation on Mac seems to
have a lot of overhread.
* Preview icons are now drawn using proper premul alpha, and never faded so
you can see them clearly.
* Also tried to fix issue with texture node preview rendering, globals can't
be used with threads reliably.
*note in order to build blenderplayer with cmake+msvc one needs to comment all smoke references in stubs.c
- scons + msvc is building fine (raising some warnings for the smole references though)
- cmake in linux should be building as well (the smoke references were inserted in stubs to please this building environment IIRC)
Seems to have been a copy+paste error (code for Vertex Color adding was pasted in place of texture paint). Restored the code from an earlier revision (from another file).
Create new orientation is now Ctrl-Alt-Space (Alt-Space is select orientation and the old ctrl-shift-c is taken by add constraints).
New orientation panel in 3d view sidebar (nkey) has operator buttons for select, create and delete. Eventually, this should become a list.
Note that orientation operators are missing notifiers to properly redraw the 3d view and its header properly.
blocking the user when opening a menu. Material and texture buttons now
display these icons in the list. Also fixes#19387, icon and full preview
render at the same time would crash.
I'm not really convinced this is thread-safe, but on the other hand also
not sure regular preview render is really thread-safe yet.
library loading was using some non-public OS X functions, which give
linking issues for me. Since OS X 10.3 standard unix dlopen() is
supported, so I just removed this code, we don't support earlier
versions anyway.
changed with the file path changes, the reason to check this first
is that it allows to edit py scripts without having to run the
build system for each change.
* Move mesh API functions to mesh_data.c, would like to keep
RNA layer fairly thin, any non-trivial functions shoud be
in their modules.
* Replace mesh.create_copy by generic id.copy.
* Fix#19250: Mesh.add_geometry() in editmode fails silently,
now gives an error.
* The code to draw only visible items was not working, giving slow
performance with many files (bug #19469).
* Fix detailed list display on non-windows, would give overlapping text.
* Fix folders with many files not displaying all items, changed short to
int in various places, was overflowing.
* Recreate layout on area resizes, file view gets out of sync otherwise.
* Workaround for v2d height not being correct with image display due to
scrollers.
* Fix view2d code to compute minimum scroller size, this would make the
scroller go outside of its bounds.
This (biggish) commit generalises the rotation modes functionality added for Bones, allowing Objects to use the various Euler Rotation orders, Axis-Angle, and Quaternion rotation representations.
I've also cleaned up the nomenclature of the rotation-related settings so that the naming styles are more consistent with each other. Unfortunately, this will break all files involving object or bone rotation animation made in 2.5 versions (2.4x will still get correctly converted).
General Notes:
* By default, Objects still default to using Eulers, while Bones will use Quaternions by default still.
* I've fixed all areas that I'm currently aware of to work with these changes. However, there are probably a few places where I've missed a few changes (i.e. auto-keyframing will need attention later).
* Removed the old "IPO-Keys" stuff from Transform code. I'm unlikely to restore this in the near future, and trying to fix that to include support for this commit would have been too much work.
- added bpy.sys as a python module - with bpy.sys.expandpath()
- moved bpy.ops into scripts/modules
- moved autocomplete into its own module from space_console.py
* Added missing RNA wrapping for Scene -> AnimData
* Fixed bug (with temp-fix) where sequence strips with no names couldn't be animated properly. Currently, this will just use the index of the strip, although that is likely to be mutable (adding/removing strips will change it).
* Removed some old unused code from action.c
Main Feature:
* It is now possible to choose which AnimData block is the 'active' one for editing, and/or select them too. AnimData blocks are generally the dark blue and lighter-blue expanders (i.e. Scene, Object, Camera, Lamp, Curve, Armature, etc.)
* Objects are no longer selected/deselected when AKEY is used to toggle selection of channels. This was getting a bit annoying.
* Following on from selection of AnimData blocks, it is now possible to select/make active an AnimData block in the animation editors, and change the active action for that block via the 'Animation Data' panel in NLA Editor's properties region.
--> Be aware that user-counts are not totally handled correctly there yet, so some funky behaviour might be seen...
--> It is possible to assign a new action, or to assign an existing one, allowing to switch between actions as in the past with Actions/IPO Editors...
Other tweaks:
* Some code tweaks towards making the 'Euler Filter' feature for Graph Editor working sometime soon
* Added some backend code for snapping the values of keyframes to a single value. Still need to work out some UI for it though.
* Shuffled the code for ACT_OT_new() around, and removed the poll() callback so that it worked in NLA too.
* Fixed some more notifier bugs with deleting bones and a few other editmode operations for Armatures.
* Threading buxfix letting MSVC Debug builds crash because of corrupted std::lists
* Adopted two property ranges
* Changed the mixdown volume to set the device volume instead of the volume of every sound.
I also removed the private redefinition of m_logicmgr in SCA_BasicEventManager, which was already defined protected in the parent class SCA_EventManager and thus caused a bug letting GE crash here because of an uninitialized pointer.
