    Hi,

    In my application I need to use the four texture coordinates (ie:
S, T, R and Q) per vertex to compensate a double perspective effect (you
can read : L. Darsa et al, "Navigating Static Environments Using
Image-Space Simplication and Morphing", Symposium on Interactive 3D
Graphics, 97, pages 25-34).

    Currently, I use pfGeoSet where we can just specify PFGS_TEXCOORD2
and not "PFGS_TEXTURECOORD4". Does anyone have any suggestions or sample
code to use four texture coordinates per vertex ?

    Thanks,
        Yann.
