Interactive 2D plots can be sluggish too, if you have enough objects in
them. It is not the backend that is sluggish. Replacing the backend does
not speed up the frontend.
OpenGL is only 'fast' if you have a frontend that exploits it (e.g. uses
vertex buffers and vertex shaders). If you just

This is a great summary of the issues related to OpenGL, and how it can
help but is not a universal panacea.

I'm using fedora (17) linux. I notice on complicated 3d plot, interactive
performance can get sluggish. I'm using nouveau driver now, but wondering if
installing nvidia driver will improve mpl 3d performance? Does mpl use opengl?
Hi Neal, my understanding is that matplotlib does not use OpenGL (thus
the terrible performance you see). You might want to look into glumpy
for mplot3d OpenGL acceleration.
