* Animations and Skeletons are now pose-only.
* Rest transform is kept as reference (when it exists) and for IK
* Improves 3D model compatibility (non uniform transforms will properly work, as well as all animations coming from Autodesk products).
* `Animation.TYPE_TRANSFORM3D` track is gone.
* Added POSITION_3D, ROTATION_3D, SCALE_3D tracks.
* GLTF2, Collada, FBX importers will only import the track types found.
* Skeleton3D bone poses are now Pos/Rot/Scale, pose matrix removed.
* AnimationPlayer and AnimationTree animate these tracks separately, only when found.
* Removed BakeReset code, is useless with these changes.
This is the first in a series of commits designed to make the animation system in Godot more useful, which includes:
* Better compatibility with Autodesk products
* Better reusability of animations across models (including retargeting).
* Proper animation compression.
* etc.
*Note* GLTF2 animation saving went broken with this PR, needs to be fixed in a subsequent one.
In case the calculation of the delta contained infinity values (division by
zero), than later the calculation of the next cell failed as the infinity value
was multiplied by zero which resulted in a nan. The nan-value caused that the
next cell was equal to the current cell which resulted in an end-less loop,
which only terminates by the maximum iterations protection.
This is solved by replacing infinity with grid_size which acts as infinity.
Before this change only rays to the sky (RAY_MISS) in the first bounce were
processed as active rays. This caused artifacts, areas were too light, when
more than one bounce were processed.
Now rays to the sky are processed as active rays for all bounces.
Smoothening positions for flat, non-smoothened, triangles is unnecessary and
caused positions to move outside their triangle which caused side-effects as
rays from those positions intersected with triangles which could not be
reached from the original triangle.
This is solved by skipping smoothening of positions for flat triangles.
A triangle is determined to be flas as its vertex normals are equal.
- Increase drag-and-drop snapping to 50 units
(from 10 units).
- Increase Snap Object to Floor maximum height to 500 units
(from 20 units).
- Increase Snap Object to Floor negative margin to 1 unit
(from 0.2 units).
All Android devices that support Vulkan support 64-bit ARM.
This also removes NEON opt-out code for ARMv7 as pretty much all
ARMv7 devices also support NEON.
