There are offline renderers that are built on similar principles to
video-game engines. That’s not the same as using OpenGL for offscreen
rendering.

I know because I did some experiments along these lines when I was
learning Android programming. OpenGL engines tend not to prioritize
efficient retrieval of rendered images back into program-local
offscreen buffers.

I think, back in those early days, OpenGL was seriously considered for
use as an offline rendering engine.

Not any more, though.
