Hi all,

Do you know of a good way to animate by sliding texture ?
I tried:

{
    pfTexture *tex;
    ulong *image;
    long comp, ns, nt, nr;

/* get texture mapping parameter */
pfGetTexImage( tex, &image, &comp, &ns, &nt, &nr);

    /* compute new parameter */
    ns++;
    nt++;
    nr;

/* set new parameter */
pfTexImage( tex, image, comp, ns, nt,nr);
}

This code does slide texture, but the program run
*really slow* (1-2 frames / second).

Is it possible to do this at a higher speed ? Perhaps
a difference approach ?

EricTran.
