Thanks to Sergey for doing code review!
* Add SCULPT_OT_dynamic_topology_toggle operator to enable or disable
dynamic topology mode
* Most brushes need little modification for dynamic topology, but for
some it won't work well and is disabled. This decision is made in
sculpt_stroke_dynamic_topology().
* For brushes that need original data (e.g. grab brush) the topology
is not updated during the stroke, but some changes to original
vertex data is accessed were made since BMesh works a little
differently from mesh/multires. This is abstracted with
SculptOrigVertData and associated functions.
* Smooth brush gets yet another set of functions, for mesh and
multires and dynamic topology and, separetely, masking
* For most brushes, the topology is updated during the stroke right
before the regular brush action takes place. This is handled in
sculpt_topology_update().
* Exiting sculpt mode also disables dynamic topology
* Sculpt undo works differently with BMesh. Since the contents of
nodes in the PBVH do not remain static during a sculpt session, the
SculptUndoNodes do not correspond with PBVHNodes if dynamic topology
is enabled. Rather, each SculptUndoNode is associated with a
BMLogEntry.
* Sculpt undo gets a few new cases: entering and exiting dynamic
topology does an undo push of all mesh data. Symmetrize will
similarly push a full copy of BMesh data, although it does so
through the BMLog API.
* Undo and redo in dynamic-topology mode will do a full recalculation
of the PBVH.
* Add some documentation to doc/sculpt.org. This could stand to be
expanded a lot more, for now it mostly contains test cases for the
undo system.
* Add SCULPT_OT_optimize operator to recalculate the BVH. The BVH gets
less optimal more quickly with dynamic topology than regular
sculpting. There is no doubt more clever stuff we can do to optimize
it on the fly, but for now this gives the user a nicer way to
recalculate it than toggling modes.
* Add BLI_pbvh_build_bmesh(), similar to the other PBVH builders but
specialized for BMesh. Whereas the PBVH leaf nodes for mesh and
grids only store a start-index and count into the primitive indices
array, the BMesh version uses GHashes to store the full set of faces
and vertices in leaf nodes
* Update PBVH iterator to handle BMesh
* Make some of the pbvh.c functions non-static so they can be used by
the new pbvh_bmesh code
* The BLI_pbvh_bmesh_update_topology() function is the main reason for
adding BMesh support to the PBVH. This function is used during a
sculpt stroke to dynamically collapse edges that are particular
short and subdivide edges that are particularly long.
BLI_buffer is a dynamic homogeneous array similar to BLI_array, but it
allocates a structure that can be passed around making it possible to
resize the array outside the function it was declared in.
* 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
* This doesn't make much difference for regular mesh/multires
sculpting, but for dynamic topology sculpting the undo stack isn't
split up by PBVH nodes, so it's more convenient to store the layer
data in PBVH nodes.
* Note that the life cycle of the layer displacement data is
unchanged -- it's only valid during a stroke with the layer brush,
gets free'd when the undo step ends.
The GPU interface for PBVH drawing gets a new pair of build/update
buffers functions for drawing BMFaces and BMVerts.
TODO: the diffuse color is hardcoded to 0.8 gray rather than using
material color.
TODO: only VBO drawing is implemented, no immediate mode.
The BMLog is an interface for storing undo/redo steps as a BMesh is
modified. It only stores changes to the BMesh, not full copies.
Currently it supports the following types of changes:
- Adding and removing vertices
- Adding and removing faces
- Moving vertices
- Setting vertex paint-mask values
- Setting vertex hflags
Undoing/redoing in sculpt and other paint modes should only use the
mode-specific undo, not global undo. It is now consistent with edit
mode and avoids tricky interaction between the two systems.
RangeTree is a simple C++ tree set for storing non-overlapping scalar
ranges. Original source from:
https://github.com/nicholasbishop/RangeTree
Also update the build systems to include RangeTree.
- dont set the color for each character, check if it changes from the previous one.
- dont memcpy text into a null terminated string to draw, instead rely on the length argument to BLF_draw().
Rotate with two-finger trackpad swipes should follow same principle as
for panning. This is first commit - for clarity.
Remaining issue is that for each system preset (in your OS) blender should
work as you expect too... pan, rotate and zoom gestures might need
each an own direction preset. Might be also messy, but then things can at
least work for everyone. Thinking it over and testing more now.
This commit adds a support of saving 16bit PNG files.
Alpha for such files would be premultiplied, would be corrected
with an upcoming alpha premul cleanup (it's not the only format
which will output 16bit image with premul alpha).
That change made all scrollwheel events be handled as if it was a swipe gesture.
Old style mouse wheel didn't work anymore.
This version should work for everyone, but we need more mac testers :)
Disconnected bones can be translated in pose mode but this translation
cannot be applied to the iTaSC representation of the armature because
there is no joint associated with it. As a result, moving disconnected
bones had no effect. The bug fix is in two parts:
1) manual or rna change in the armature pose will cause automatic
rebuilding of the iTaSC scene
2) the iTaSC scene is now built from the current pose instead of
armature rest pose
from Patrick Boelens (senshi). with modifications to split it into its own function.
also added C style multi-line comment support /* ... */
I've left out the part of this patch that sets the language in the space, since I think this might be better stored in the text block.
For now it simply uses OSL syntax highlighting when the extension is '.osl'.
Example is for physics like Cloth or Hair Dynamics that start on a shaky state for a few frames until they settle (for say baking subtle grass or hair movement).
Reviewed on IRC by kaito, Uncle_Entity and DingTo.
User preference "Rotate around selection" now works for all input operators.
(Didnt for new default)
Note: the default will only rotate around selection, zooms remain to view center.
Our view pivot methods are not well definied at all...
- UV Image editor and other 2d views didn't zoom for CTRL+swipe yet.
(2 finger trackpad, 1 finger mighty mouse)
- Switched defaults for 3D window swiping...
- default rotate view
- SHIFT for translate
- CTRL for zooms
This makes all editors use 'swipe' like 'middle mouse', and not
like scrollwheel (as in releases).
This is nice for consistancy, but it still feels a bit weird...
Of course users can config this in keymaps. We need a sensible
default though, and to make a 2D input input device behave like
middle mouse seeems more sensible than like a 1D wheel...
Proposal therefore for defaults:
- 1D scrollwheels: zoom in 3d, zoom in 2d, but scroll for list views.
- 2D trackpads: pan for all 2d views, rotate for 3D
I'll check with frequent trackpad users about this and we can freeze it
before release. Give it a try :)
In 2.64, input for using an NDOF device included all 6 DOFs - including panning.
That makes using it for many people (including beginners like me) too hard, you
very quickly lose the 3d view rotation pivot, as if you are in free fly mode.
Fredrik provided an updated patch, which restores the 2.63 method to only
dolly and rotate by default. The new "all dof" operator is hidden in the keymaps
behind modifier keys SHIFT + CTRL. Users can set this in their configs of course.
As usual, we should be careful changing accepted defaults, and provide new
options as additional choice only.
A useful todo is to make user preference "around selection" work well.
Will check on this now too.
scrolling and inertia.
Now Blender uses this - if you have 10.7. Otherwise it just falls back on the
old code.
Try it, makes a huge difference :)
Next todo: how to configure this well, so you can have trackpad (or mighty mouse)
zoom as default in 3d views.
