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:

Are there any plans to remove the OpenGL dependency on FieldTrip ? Is this desirable (i can argue that it is) ?

and Conal Elliott replied:

Personally, I want to move away from OpenGL to a GPU-centric architecture.

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? -- ___ ___ __ _ / _ \ / _ \| | | | Gregory D.
