James Liu 1523c38ce8 Directly extract joints into SkinnedMeshJoints (#6833) ... # Objective Following #4402, extract systems run on the render world instead of the main world, and allow retained state operations on it's resources. We're currently extracting to `ExtractedJoints` and then copying it twice during Prepare. Once into `SkinnedMeshJoints` and again into the actual GPU buffer. This makes #4902 obsolete. ## Solution Cut out the middle copy and directly extract joints into `SkinnedMeshJoints` and remove `ExtractedJoints` entirely. This also removes the per-frame allocation that is being made to send `ExtractedJoints` into the render world. ## Performance On my local machine, this halves the time for `prepare_skinned _meshes` on `many_foxes` (195.75us -> 93.93us on average).  --- ## Changelog Added: `BufferVec::truncate` Added: `BufferVec::extend` Changed: `SkinnedMeshJoints::build` now takes a `&mut BufferVec` instead of a `&mut Vec` as a parameter. Removed: `ExtractedJoints`. ## Migration Guide `ExtractedJoints` has been removed. Read the bound bones from `SkinnedMeshJoints` instead.		2022-12-20 16:17:05 +00:00
