契约
- assert BufferAttribute instantiates with underlying typed array, computing count from array length and itemSize
- assert setXYZ mutates vector components at logical item indices in the underlying array buffer
- assert copyAt copies all vector components from a source attribute index to target attribute index
- assert applyMatrix4 transforms 3D positions in place by affine 4x4 matrix multiplication
- assert applyNormalMatrix transforms vectors by 3x3 normal matrix and normalizes results in place
- assert clone creates an independent deep copy of the BufferAttribute and its underlying typed array
- assert addUpdateRange and clearUpdateRanges manage partial buffer update intervals
- assert toJSON serializes attribute configuration and typed array data
