示例

SkinnedMesh.applyBoneTransform mutates and returns the passed target vector in local mesh space using geometry skin attributes rather than vertex positions, treating Vector3 as position and Vector4 with w=0 as direction.

常见的想当然

SkinnedMesh.applyBoneTransform loads vertex coordinates from geometry.attributes.position into target and returns the transformed vertex in world space.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• SkinnedMesh.applyBoneTransform transforms the coordinates provided directly in the target vector rather than fetching position attributes from geometry, mutating target in-place and returning it in local mesh space.
• Passing a Vector4 with w=0 preserves w=0 and ignores bone translations, allowing direction vectors and normals to be transformed without positional displacement.
• Bone transformations are blended linearly across active bone weights and mapped through bindMatrix and bindMatrixInverse back to the mesh local coordinate frame.
