契约
- BufferAttribute.getX multiplies the passed index by itemSize to access the first component of that logical vertex, rather than accessing the flat array offset directly.
- BufferAttribute.getX with normalized true decodes Int8Array values using Math.max(value / 127.0, -1.0), mapping both -128 and -127 to -1.0.
- BufferAttribute.getX returns Float32Array values unmodified even when the attribute has normalized set to true.
- BufferAttribute.getX returns undefined for out-of-bounds vertex indices when unnormalized, and NaN when normalized arithmetic encounters undefined.
