This assumptions are now made:
- Internally float buffers are always linear alpha-premul colors
- Readers should worry about delivering float buffers with that
assumptions.
- There's an input image setting to say whether it's stored with
straight/premul alpha on the disk.
- Byte buffers are now assumed have straight alpha, readers should
deliver straight alpha.
Some implementation details:
- Removed scene's color unpremultiply setting, which was very
much confusing and was wrong for default settings.
Now all renderers assumes to deliver premultiplied alpha.
- IMB_buffer_byte_from_float will now linearize alpha when
converting from buffer.
- Sequencer's effects were changed to assume bytes have got
straight alpha. Most of effects will work with bytes still,
however for glow it was more tricky to avoid data loss, so
there's a commented out glow implementation which converts
byte buffer to floats first, operates on floats and returns
bytes back. It's slower and not sure if it should actually
be used -- who're using glow on alpha anyway?
- Sequencer modifiers should also be working nice with straight
bytes now.
- GLSL preview will predivide float textures to make nice shading,
shading with byte textures worked nice (GLSL was assuming straight
alpha).
- Blender Internal will set alpha=1 to the whole sky. The same
happens in Cycles and there's no way to avoid this -- sky is
neither straight nor premul and doesn't fit color pipeline well.
- Straight alpha mode for render result was also eliminated.
- Conversion to correct alpha need to be done before linearizing
float buffer.
- TIFF will now load and save files with proper alpha mode setting
in file meta data header.
- Remove Use Alpha from texture mapping and replaced with image
datablock setting.
Behaves much more predictable and clear from code point of view
and solves possible regressions when non-premultiplied images were
used as textures with ignoring alpha channel.
* New topology panel in 3D view toolbar with the enable/disable button
for dynamic topology and other controls
* Ctrl+DKEY to toggle dynamic topology
* Shift+DKEY to show a radial control for detail size
* Add a detail_size field to the Sculpt struct, two new sculpt flags,
and a Mesh flag for dynamic-topology mode; that's it for file-level
changes needed by dynamic topology
* Add RNA for the new DNA field and flags
* Add a new icon for dynamic-topology created by Julio Iglesias. TODO:
update the icon for the new SVG icon format
* Add a SculptSession function for converting from BMesh to Mesh,
handles reordering mesh elements and setting face shading
bake_action tries to make kind of a 'visual keying'... On one side, this is rather stupid when you keep constraints (in this case, keying actual loc/rot/scale transforms, i.e. matrix_basis, is enough, doing more would lead to unexpected behavior with some constraints). On the other one, making a good visual keying of bones is *really* tricky, so now using the new object's convert_space() func to compute that (when the user chooses to remove the constraints).
Incidentally, this greatly simplifies the code of bake_action!
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.
This commit adds a UI option in the Render properties to enable the new material caching in the converter. This caching can cause problems with Singletexture and Multitexture materials when texface is being used to handle materials. By default this option is enabled and users with broken games have two options:
1) Fix up their materials so they are properly using textures
2) Disable the material caching and take a speed hit during conversion time
Regardless of the setting, caching is always enabled for GLSL materials.
- blends from current weight into alpha zero.
- uses brush alpha & curve.
- respects weight paint vertex/face select modes.
- updates realtime.
Access With
- Alt+LMB (linear gradient)
- Ctrl+Alt+LMB (radial gradient)
note:
- WM_gesture_straightline_* are used but not well suited to this task, may end up replacing with own modal operator.
- Key handling works but needs to be done better.
New Bone option: "Relative Parenting".
This makes Child-Objects of Bones transform similar to how deformations
of bones are calculated. Allows to move bones in editmode to set pivot.
The option is in Bone Panel, with clear label.
It is ON now by default when you add new bones
Requested by Kjartan, our famous robot designer :) For "hard body rigs" it's
very useful.

Note: NodeTree and Node currently use standard python classes generated by bpy for now. The customnodes branch defines such classes as well, with specialized metaclasses for use with ID properties. Not needed in trunk yet.
- Recoded soft shadow drawing for menus, giving better predictable results
(and round off nicer on top side, was looking bad still)
- Brought it under DPI control
- Added Theme setting to control size and strength for it.

- yes, this does break scripts, but the api is marked experimental.
ED_region_draw_cb_activate() adds a callback to a region type whereas the api made it look like the callback was being added to the region instance.
Use a class method on bpy.types.Space to manage region drawing, eg.
was:
self._handle = context.region.callback_add(draw_callback_px, args, 'POST_PIXEL')
is now:
self._handle = bpy.types.SpaceView3D.draw_handler_add(draw_callback_px, args, 'WINDOW', 'POST_PIXEL')
Since the window manager is needed for keymaps this is kept as an exception.
some addons will need updating, but in every case I've seen addons should not be accessing the context while registering.
(bad stuff! - declaring the scene as a global variable - which crashes when the users loads a new file, manipulating the active object or scene... tsk tsk)
* Cleaning up the conversion code to avoid a per-face material conversion. Materials are now stored in buckets and only converted if a new material is found. This replaces some of Campbell's earlier work on the subject. His work wasn't as thorough, but it was much safer for a release.
* Shaders are only compiled for LibLoaded materials once. Before they could be compiled twice, which could really slow things down.
* Refactoring the rasterizer code to use a strategy design pattern to handle different geometry rendering methods such as immediate mode, vertex arrays and vertex buffer objects. VBOs are added, but they will be disabled in a following commit since they are still slower than vertex arrays with display lists. However, VBOs are still useful for mobile, so it's good to keep them around.
* Better multi-uv support. The BGE should now be able to handle more than two UV layers, which should help it better match the viewport.
- Exported via Inkscape a 16 and 32 pixel bitmap version
- Use these as mipmap levels for OpenGL texture drawing.
- Changed code to get right sizes for drawing icons - better than last week's method.
Todo:
- Custom icons don't work yet (old one)
- Missing icons in the svg
- The .sh script for inkscape needs changed to support this
(now do manual saving)
Also fixed CTX_FOO_ macros when building without i18n, those were kinda wrong.
And hid i18n ui section in userpreferences when built without its support too.
This implements AO baking directly from multi-resolution mesh with much
less memory overhead than regular baker.
Uses rays distribution implementation from Morten Mikkelsen, raycast
is based on RayObject also used by Blender Internal.
Works in single-thread yet, multi-threading would be implemented later.
