View Full Version : Rendering without displaying to the screen

Alright, here's a question from the gallery of idiots.

My latest project at work involves testing of some image recognition algorithms, and I need to set up a 3D scene and construct an array of data (essentially a bitmap of the screen) for these tests to be performed on. The solution I've come up with, which to me seems to be the most inefficient, but like I said, I'm an idiot, is to render the scene internally in openGL, never even send it to the screen, and then grap the data I need from the framebuffer. Is this a viable option, or would I do better to come up with some other implementation that can construct my bitmap from a few dozen specified vertices in 3 dimensional space and possibly a few image files I'm going to be using for my background? I don't know if what I am trying to do in openGL is even possible, I've only been working with it for about the past week. Any suggestions, comments, insults, etc. would be most appreciated.
