This is just idle musing on my part, but have you tried object
graphics? Plotting semi-transparent polygons successively offset
along the Z-axis towards the viewer should built up density in the
right way. You only need to read the pixmap at the end and you can
take advantage of the fact that OpenGL is optimised for fast polygon
plotting (and often accellerated to boot).
