Animator

actual class Animator

Animator updates matrices according to glTF animation and skin definitions.

Animator handles two primary tasks:

  1. Updating matrices in TransformManager components based on glTF animation definitions

  2. Updating bone matrices in RenderableManager components based on glTF skin definitions

Usage pattern for animated skeletal meshes:

animator.applyAnimation(currentIndex, time)      // Apply current animation
animator.applyCrossFade(previousIndex, prevTime, alpha)  // Blend with previous (optional)
animator.updateBoneMatrices()  // Propagate bone transforms to renderables
