I want to render a bckground texture. I tried to render it using Channel
Call back function. But no texture is being rendered.Even the pfb model
which I am supposed to draw infront the background is not seen. Can
anyone suggest where I am going wrong

The following are the
few lines from my application.

In the main function I am calling Callback Function.

pfChanTravFunc(chan, PFTRAV_DRAW, DrawChannel);

// Function for rendering the background texture

void DrawChannel(pfChannel *chan, void *data)
{

        int imagebuffer[500][500];
        int j,i;
        int k;
        pfVec3 far, dummy;

        for(i=0;i<500;i++)
        {
                for(j=0;j<500;j++)
                {
                        imagebuffer[i][j] = (i+j)%255;
                }
        }

        glClearStencil(0x0);
        glClear(GL_STENCIL_BUFFER_BIT);

        pfGetChanFar(chan, far,dummy,dummy,dummy);
        glRasterPos3f(farPlaneLL[0], farPlaneLL[1],
farPlaneLL[2]*0.99999);
        glDrawPixels(winWidth, winHeight, GL_RGB,GL_UNSIGNED_INT,
imagebuffer);
        pfDraw();
}
