The issue was caused by the following construction:
def = env['SOMETHING']
defs.append('SOMETHING_MORE')
Since first assignment was actually referencing environment option it was totally
polluted hawing weird and wonderful side effects on all other areas of Blender.

predictable/responsive
The old method:
The "old" method used the node dimensions to get a number of lines and checked if they intersect with the node link. Issue with this is that only a small part of the actual node surface is checked, making the method a bit unpredictable or unresponsive.
The new method:
The new method checks for intersections within the entire node surface. If multiple links are intersected, the node with the smallest distance from the *upper left corner* to the link is chosen.

These arrays aren't especially big or likely to fail.

Use polygons for calculation
|

Should be useful for debugging cases when enabling the option doesn't
cause any performance improvements.

Need to find better approach for dealing with shadeless materials.
|
|
The idea is to cut as much code as possible and use compile-time
ifdefs rather than runtime if() statements.
Gives about 2x speedup on catmark_car model from OpenSubdiv repository
making our FPS much closer to what glViewer is capable of.

This could cause problems since they could be any int,
then passed directly to internal functions that assume bools.

It works similar to getActionFrame(), you have to give a layer or not (for layer 0) as the argument and it returns the name of the animation that the object is currently playing.
Example:
```
import bge
own = bge.logic.getCurrentController().owner
own.playAction("SomeAction",0,20)
print(own.getActionName())
```
>> SomeAction
Here is an example file, just open the blend file with the terminal opened
and press P, you can see how the current animation is being printed:

This actually requires some bigger work to make it fully supported but
for now at least avoid breaking shading with OpenSundiv option disabled.

Patch by Tilman Blumhagen, thanks!

Use OpenGL 3.2 extension ARB_draw_elements_base_vertex, which allows us
to add offset in index buffer indices automatically. This should reduce
the number of draw calls significantly.
We may have some errors on the Mac with VBO setting off.
OSX OpenGL extensions don't play well with vertex arrays.
Will test that more later.
We might also use a full element buffer here, like we do when hiding
some quads, but this approach keeps the memory savings intended
originally.
|
|
The idea of this commit is to make it so we can enable OpenSubdiv by default
for the release builds but keep it limited to the viewport only for a specific
meshes. This is a temporary solution for until all the needed features are
supported on the OpenSubdiv side.
Flag itself is done as a dedicated field in modifier DNA so we can easily
remove it in the future without ending up with some temporary flag hanging
around forever.
|

Was overdrawing the buffer, in case of fast drawing just use one
draw call. Should also make performance quite smoother.
Note:
Just discovered we are doing one draw call - per grid - in multires
apparently to keep reusing the same element buffer.
This is horribly, dreadfully slow and will check about fixing it later.

The issue was caused by CCG code being confused by number of geometry returned
by utility functions in the case of the skipped grids.
Made it so that code is always only working with CCG data and handled drawing
code in a bit special way now.
This solves such crashes as i.e. snapping.
|
|
|
|
Cases like using subsurfed object as a boolean operand can't be evaluated
on GPU and needs to have all the CCG on CPU.
This commit resolves existing configuration to survive, but new configurations
would need to have some sort of forced object update so all the data is being
moved on CPU if it was previously on GPU.
|
|
This case is now supposed to be supported by OpenSubdiv.
|
|
Was own mistake in the last minute fixes, now matcaps should
work just fine.
|
|
|
|
|
|
This is just updating code from our side, actual evaluation is still
disabled because it doesn't support face farying data evaluation.
|
|
|
|
non-manifold case didn't start ordering from the correct edge.
|
|
This way the result matches GPU viewport and becomes really close to out
legacy subsurf code.
|
|
|
|
This check doesn't handle multiple non-manifolds cases which is rather
really annoying currently.
|
|
Previous version of code didn't handle cases like hourglass connectivity
with loose edge. The new code is supposed to handle all this cases.

buffer objects again

Use for mathutils.bvhtree
|
|
Detect when there are < 3 corners & automatically calculating the span isn't useful.

Wasn't applied relative to the active vertex.

Crash was caused by missing field in NodeShaderTexPointDensity.
Committed with @dingto blessings.

Was intended to be disabled in rBa3b86611a8182, but disabled 3D View FPS drawing instead of VSE drawing. Triple checked but 3D View doesn't draw FPS now, so everything seems fine now.
Note: To recreate this you had to play animation once before scrubbing.
|
|
After scrubbing, Blender kept thinking an animation is played (see animation "Play" button), even after mouse release. This resulted in a couple of crashes, e.g. by pressing Alt+a and then Esc.
(Also minor cleanup)
