Hi, I use a software buffer of the size of my window as the render target for my raytracer. After the raytracer has finished I draw the buffer with glDrawPixels to the screen. What I would like to achieve is to draw the bboxes of the kd-tree on top of the raytracer image. However this only works if I comment out the glDrawPixel function. Any idea how I could display the bboxes together with the raytraced image? thanks, quak
