attributeView Field Array Elements
Element Value Description
bufferView   The label of a bufferView.
byteOffset   The offset to the first byte of this section relative to the beginning of the DATA portion of the file.
byteStride   TBD
componentType   TBD
type VEC3 | VEC2 | ... A character code that describes the encoded data.
count   The number of elements of type in this attributeView
decodeOffset   A numeric array that indicates the offset to be applied to each element of this attributeView data. There is exactly one value for element of type.
decodeScale   A numeric array that indicates the scale factor to be applied to each element of this attributeView data. There is exactly one value for element of type. The real value for each stored value is computed as
R[i,j] = S[i]*D[i,j] + O[i]
where,
i
is the type index
j
is the data index
R
is the real data
S[i]
is the decodeScale element i
D[i,j]
is the stored data
O[i]
is the decodeOffset element i
