    Hi, I am writing a 3d engine and I was woundering what the best
alhroritm is for perspective texture mapping. 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,
