Eh, I beg to differ. Rotation about the origin is one of the most common operations in 3D graphics, since you typically treat the origin as model space and just do one final translation to get your models into world space. This is essentially what OpenGL does when you build your model and world transformation stacks. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
