I have a bunch of hard-coded global 3D arrays of floats. I can loop through an individual 3D array just fine, but I also want to loop through all the 3D arrays.

Alternatively, we can split the 3D array into three 2D arrays, one for each colour channel. Note, this is different from above where we kept the entries as RGB vectors, where just two entries were 0.

Light source array: A number of light sources arranged at equal intervals for reconstruction of 3D images. Viewing zone: The range in which 3D images can be viewed.
