Class: MeshDeformer
Defined in: src/io/raycast/MeshDeformer.ts:110
CPU replica of the vertex-shader deformation (morph targets, then skinning) used by ray queries, so picks match what is drawn.
Skinning reads each bone's current world matrix from the same global matrix slot the shader reads (models.matrix[...]), multiplies by the skin's inverse bind matrix and blends with joints0/weights0 (and joints1/weights1), producing world-space positions exactly as the shader's getSkeletonWorldMatrix_*. Morphing applies position * baseInfluence + Σ influence_i * a_morphPositions_i.
Results are cached per renderer and recomputed only when the skinning matrices or morph weights changed; the cost is O(vertices) per change. Normals are deformed with the blended matrix (exact for rotation and uniform scale).

MeshDeformer
Methods
isDeformed()
staticisDeformed(renderer):boolean
Defined in: src/io/raycast/MeshDeformer.ts:114
Whether the GPU currently deforms this renderer's geometry (bound skin, or non-trivial morph weights).
Parameters
renderer
Returns
boolean
deform()
staticdeform(renderer):DeformedMesh
Defined in: src/io/raycast/MeshDeformer.ts:122
Deform the renderer's geometry as the vertex shader does and return the cached CPU geometry, or null when nothing deforms it.
