  I would be grateful if anyone had suggestions about software that could (1) create 3D surface plots, (2) handle transparency/alpha blending, (3) generate output in some vector graphics format that preserved the transparency. I could also live with a combination of two programs, one to generate the basic figure and another to modify the output surface to a transparent color (but preserving vector-ness).

  I've been working with the rgl package, but can't get the transparency to work for vector output (rgl.postscript). The rgl package uses the gl2ps library -- by default transparency is disabled in the output (GL2PS_NO_BLENDING is set), giving reasonable PDF output but without transparency. Enabling it in the source code gives ugly results.

  I ported my graphics to Mathematica, but its PDF output (and SVG output) are both wonky.

  Any ideas???
