Hi JJ, Thanks for the examples! I indeed suspected the anti-aliasing as well. I'll include an option for linecolors = facecolors soon (probably this weekend); it seems to be a good solution.
After that I'll try to implement usage of the Gouraud shading, although I fear that this will not look nice with edgecolors=facecolors, so anti-aliasing might have to be turned off in that case. Is it perhaps possible to only render the surface with AA off?
