Hi all, In https://trac.sagemath.org/ticket/23696 we are working on bringing matplotlib-2.1.0 to sage. This is a big upgrade, in fact it would have been easier to upgrade to 2.0.2 but we missed that window.
The big change in 2.1.0 is that delaunay that was deprecated since 1.4.x has finally been removed. This is a big change for us because in sage/plot/plot3d/list_plot3d.py we used an interpolation linked to the delaunay module: “natural neighbour”. It was sometimes mislabelled as “nearest neighbour” but this is different. The “natural neighbour” interpolation is gone and I don’t think we should adopt the old matplotlib code for it. Someone could develop a new implementation of “natural neighbour” in sage but that would take some time. In the mean time we had a look at what interpolation are available from matplotlib and scipy for look and speed. I would very much want to change the default to a “new” (as in not used in sage before) interpolation from scipy “CloughTocher2D”. It is reasonably fast and looks quite good but I am open to other suggestion. In particular if you have other interpolator from other code shipped by sage to suggest. Further, since it changes a default, it would be good if their was a consensus on the choice.
