.array : TypedArray
The array holding the interleaved buffer attribute data.
.count : number (readonly)
The item count of this buffer attribute.
.data : InterleavedBuffer
The buffer holding the interleaved data.
.isInterleavedBufferAttribute : boolean (readonly)
This flag can be used for type testing.
Default is true.
