Hmm, not sure what you mean by that. I used ordinary trig and Windows GDI to generate 360 rotated pics at program start, then accessed the stored HBITMAPS at run-time. It works pretty good for me, and I doubt anyone can really tell the difference between a 1-degree rotation and a .2-degree rotation in the image unless it's a monstrously huge picture.The only way to rotate correctly to every angle is to use Direct3D to render a textured quad.
