Hi, performers,

I'd like to do real time texture mapping using pixels from a pbuffer. I
managed to get pfChannel render into that pbuffer, but don't how to read
the pixel out of it for texture mapping because:
pfTexture::setImage(uint* image...) requires an array of UINT for
texture

So, I think I should use glReadBuffer() to set the framebuffer first
before calling glReadPixels to get the array of pixel. However, there is
no option for me to tell glReadBuffer to read from a pbuffer:-(

What should I do then?

Thanks!

Liu
