Detailed Description

4D buffer indexer: [dim0][dim1][dim2][dim3]

Computes linear index as: dim0_idx * (dim1 * dim2 * dim3) + dim1_idx * (dim2 * dim3) + dim2_idx * dim3 + dim3_idx

Common usage patterns:

• Camera material properties: [source][primitive][band][camera]
• Specular radiation: [source][camera][primitive][band]
