With this change finally one can use compound collisions (like those created
by Gridmaps) without serious performance issues. The previous KinematicBody
code for Bullet was practically doing a whole bunch of unnecessary
calculations. Gridmaps with fairly large octant sizes (in my case 32) can get
up to 10000x speedup with this change (literally!). I expect the FPS demo to
get a fair speedup as well.
List of fixes and improvements:
- Fixed a general bug in move_and_slide that affects both GodotPhysics and
Bullet, where ray shapes would be ignored unless the stop_on_slope parameter
is disabled. Not sure where that came from, but looking at the 2D physics
code it was obvious there's a difference.
- Enabled the dynamic AABB tree that Bullet uses to allow broadphase collision
tests against individual shapes of compound shapes. This is crucial to get
good performance with Gridmaps and in general improves the performance
whenever a KinematicBody collides with compound collision shapes.
- Added code to the broadphase collision detection code used by the Bullet
module for KinematicBodies to also do broadphase on the sub-shapes of
compound collision shapes. This is possible thanks to the dynamic AABB
tree that was previously disabled and it's the change that provides the
biggest performance boost.
- Now broadphase test is only done once per KinematicBody in Bullet instead of
once per each of its shapes which was completely unnecessary.
- Fixed the way how the ray separation results are populated in Bullet which
was completely broken previously, overwriting previous results and similar
non-sense.
- Fixed ray shapes for good now. Previously the margin set in the editor was
not respected at all, and the KinematicBody code for ray separation was
complete bogus, thus all previous attempts to fix it were mislead.
- Fixed an obvious bug also in GodotPhysics where an out-of-bounds index was
used in the ray result array.
There are a whole set of other problems with the KinematicBody code of Bullet
which cost performance and may cause unexpected behavior, but those are not
addressed in this change (need to keep it "simple").
Not sure whether this fixes any outstanding Github issues but I wouldn't be
surprised.

There was a bug that could result in most bone aabb boxes ending up with
tiny size upon import and mess up with culling of skeletal meshes. This
fixes it.

Fixed TextureArray and Texture3D issues
|
|
|
|
- Texture arrays and 3D textures weren't working previously due to an
incorrect number of calls to glTexImage3D with incorrect level parameters.
This change fixes that.
- Fixed the incorrect calculation of the byte size of layered textures.
- Added the layer count to the debugger info when viewing video memory usage.

I decided to modify code in a defensive way. Ideally functions

CLAMP limits the value between the two bounds, so for unsigned ints
it should be replaced by MIN(val, max), not MAX.

Fix many asan and ubsan reported issues
|
|
The code already referred to "Basis", it's just the file name that was different for some reason.
|
|
This allows most demos to run without any ubsan or asan errors. There
are still some things in thirdpart/ and some things in AudioServer that
needs a look but this fixes a lot of issues. This should help debug less
obvious issues, hopefully.
This fixes #25217 and fixes #25218

This reverts commit 5de5a4140b9a397935737c6ce0088602be6840d7.
@reduz still intends to rework it in the future, and it's convenient to
test if issues are specific to Bullet or not, so we keep it around for
the time being.
