I took some AI generated images and ran a blender script on them to map greyscale values to a height map. If you change the colors from dark to light this makes the image really visible in a way similar to what I think Hueforge does. There really isn't any more complicated math than that, I don't know how transmission distance works so there is no prediction that the print comes out looking any specific way. Anyways each print is about 2 hours long and has 3 color changes. I've gotten the best results with starting with black then a darker color a complementary color, and finally white.
