Perspective not in the middle of the screen

OpenGL OpenGL: Basic Coding

I’ve got a question which is quite hard to explain. Is there a way that the “source” of the perspective is not in the middle of the “camera”? It will mostly be used in rendering screenshots in poster quality (making many small pictures to fit them together to one big picture)

thanks in advance Gutland

Yes - define your perspective using glFrustum.
You can specify left, right, top and bottom “edges of perspective”.
