 		This class stores data for an attribute (such as vertex positions, face indices, normals,
 		colors, UVs, and any custom attributes ) associated with a [page:BufferGeometry], which allows
 		for more efficient passing of data to the GPU. See that page for details and a usage example.

 		데이터는 모든 길이가 벡터로 저장되며 ([page:BufferAttribute.itemSize itemSize]로 정의된 값),
 		일반적으로 인덱스 값으로 전달될 경우 메서드 내에서 밑줄이 쳐지며 자동으로 벡터 길이에 곱해집니다.
