Screen reflection program?

OpenGL
1

I was wondering if anyone knew if it was possible to “mirror” video in os 10.2 using open gl. I would like to be able to view a reflection of the screen (off of my windshield), but can’t find any info on how it could be done. Any thoughts or sugguestions would be appreciated.

thanks,

I don’t know if this is helpful, but Apple’s just posted sample code showing how to grab the screen. Once you’ve got the image, you can presumably do what you want with it.

Graphics 3D: glGrab
This sample shows how to use OpenGL to grab the contents of the
screen via a DMA transfer to reduce the load on the CPU.
