As I understand it, it plots triangles and/or wireframe in the end.
Currently I think our plotting mainly works with surfaces. How can you
plot a 3D array of arbitrary data points? You need to convert it to
some triangles first, e.g. do you want to plot contours (isosurfaces)?
Or do you want to cut a plane in your 3D data points and plot that
plane?

The best thing is to just look into our sources, it's pretty well documented.
