I've come back to this at last and I'm trying a new approach.

I've generated a texture atlas of 64 128 by 128 images which I want to volume render.

It's not very good at this stage as the only database of stars I could find was limited to 88,000 stars.

I have parsed the stars into a 128 by 128 by 32 array and counted the number of stars in each bin. I have used this value as alpha and grabbed the colour from the standard galaxy rendering to end up with an 8 by 8 array of textures.

Does anybody have a volume renderer that can handle this type of texture atlas before I spend hours writing one and find out the data is rubbish.
