Hi all, im trying to program a simple model viewer application for use as a college task.

I am stuck at the moment with the mouse controls, im simply trying to make it so that when you click on the screen and then drag the screen, the object will rotate, i can get it to rotate but i need it to corrosponed to screen axis rather than the object axis, for example i rotate the object right but then if i rotate it up the up is now facing right if you see what i meen, where as i want the up to stay at the front even if it has been rotated, resetting the objects axis might fix this after each movement, but im not sure how.

Can anyone help please.

What if you made the camera orbit around the object? That way you won't have to deal with crazy object angle calculations. Check this out:


Is that what you're looking for?

Good luck
