契约

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