To see this as wavelets in a simple case such as the lowres cube map, 
imagine a 1D wave for each face on each voxel.
Then you have a 2D grid of waves running from top to bottom, another from 
left to right and another from front to back.
This would be for a monochrome image, so multiply by 3 to encode the HLS 
values.
