The invers metod look pretty fast but it created some weird effects. (not just in my tests but in some other demos tests and games.) In exterme angles when you move the texture seem to wobel between the segments of the texture's U/z V/z are interpolated. I herd there was a fast accuret way to do it using a quadradic formula and bilinearly interpolating it. Any ideas? thanks, -Ardy http://home.earthlink.net/~broadview/
