The funniest part is that we are close to carnival in Brazil... vacation time... more than 30C... and I am the one to try to get back to the track...Any clue on how to rotate the object? Examples?
example(spin3d)
Also, still on the same object. If I change zoom, position, etc. with the mouse, where to query this information, for reproducing the same image later on?
See ?par3d. When you release the mouse, the "userMatrix" is updated to reflect the current position. You may also have changed "scale" and "projMatrix".
