OT: 3d surfaces with transparency

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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???
You could consider wireframe from lattice, but this has many caveats. For an example, see http://dsarkar.fhcrc.org/lattice/book/figures.html?chapter=06;figure=06_18;theme=stdColor;code=right For that matter, whats wrong with persp? -Deepayan
