pst-solides3d (part of
pstricks bundle for LaTeX) to generate the following surface.
The surface is not a mesh, but a collection of disjoint quadrilateral patches, each with a uniform color. The overall effect looks like a gradient effect, but it is not true smooth gradient (if you consider 3D rendering, it usually cannot produce vector format graphics). I want to turn it into a smooth gradient surface just like in
The problem with
blend (of these quadrilateral patches) is that it does not produce a satisfying result. So I had to take the pain to work with
gradient mesh. To create such a strange shape of gradient mesh is also difficult. It does look better with very coarse mesh (see the following), but it is still very time consuming.
So my question is, is there a way to translate the mesh generated by
PSTricks into a gradient mesh in
Alternatively, if there is a better way to do this, I would also like to know it. Thank you.
