I haven't read anything about graphics routines of this sort yet, but started out with the idea of using sin and cos to rotate the dots around a y axis. I assume that the dots are a constant distance from the center and then just change the angle they are on the circle that a dot would create when circling an axis. This just doesn't seem right and I know it can't be the best way of doing it. Surely there is a good book on this topic? Does anyone know of any really good book that is tailored to that amiga? Byron
