[Fieldtrip] Moving from OpenGL to GPU-centric architecture

[Gregory D. Weber]

Greetings! I am a beginner to FieldTrip (which I have not yet
even been able to install) and to computer graphics in general
(which my questions will probably make obvious).

On Mar. 6, Hugo Gomes asked:

and Conal Elliott replied:

Now my questions:

Since OpenGL is the only 3D graphics framework that I am familiar with,
I am wondering how a "GPU-centric architecture" would be different.
Indeed, I was under the impression that OpenGL _is_ an API for
controlling the GPU; so another way of putting my question is:
if that's not GPU-centric, then what is?

And why would that be better?
