I really had my hopes up for VisPy for this (GPU-accelerated 3D plotting). It was supposed to be the convergence of 3 or 4 previously existing OpenGL-based plotting libraries. However, 4 years after starting development, it's still in early stages and not really usable unless you want to code shaders by hand.
