Marsh) Newsgroups: comp.graphics Subject: 3D Rotations of 2D Bitmap Keywords: bitmap rotations Message-ID: <2364@cod.NOSC.MIL> Date: 16 Oct 90 19:09:32 GMT Organization: Naval Ocean Systems Center, San Diego Lines: 18 Now, before anyone responds with a "read the FAQ", I have, and this question is about a different problem. I need to rotate a 2D bitmap around all three axis (X and Y, in addition to Z). I haven't been able to locate the article referenced in the FAQ, so the code I have does little good to explain how I could expand the shear transform method to all three dimentions? Does anybody out there have code to do a rotations of a 2D bitmap in 3D using the shear transform? This seems much more straight-forward than doing a 'normal' transformation backwards (to avoid holes). Thanks in Advance!
