@bplus Thanks, it was a fun project
In my Work In Progress thread, I was concerned that the mapping I created was giving mismatches in the 3D images. I did do a bit of optimisation but my method did leave some mismatching around the spheres. Its hardly noticeable on the Moon, and the Earth is spinning so fast (it has to) that you can't detect it). As the Sun has axis rotation faster at the equator than at the poles, the mismatching is irrelevant.

Guys, another _MAPTRIANGLE graphics program. And for me the fun part was working out the necessary mapping. The program needs a lot of CPU effort, and I suppose that an equivalent OpenGL program would be much more efficient. One point of interest is that the Sun rotates at different speeds from equator to poles. It turned out that this was easy to do with my mapping scheme. Would that be any easy thing to do in OpenGL?
