I'm having trouble figuring out how to clip a rectangular region on a larger Direct3D surface. I have a surface the size of the screen that holds my background image, and I need to prevent a small part of the surface from being redrawn because there is a DirectShow video window on top of it that flashes when the surface is redrawn.
Please be detailed in how to accomplish this as I am fairly new to Direct3D.
Thanks,
Dustin
