...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???
