can I create isosurface contours from list data?
I've recently started playing with sage 3d plotting. I was wondering if there was any way I can make 3D isosurface contour plots from list data. I'm able to take 2D matrix data and make 3D surface plots using list_plot3d. But I want to take 3D matrix data and make isosurface contour plots in a way similar to mayavi's contour3d function.
