After a bit more tinkering, it seems that setting the depth cueing mode to Exp2 does the trick. For the other modes, (most) objects viewed through a transparent surface are shaded as if they're in the foreground.

Betreff: vmd-l: Tachyon transparency and depth cueing


Just wondering: is there a “magic” command-line switch in Tachyon which gets depth cueing working correctly with transparency? Every time I attempt to render this combination using the standard switches, anything viewed through a transparent surface loses its “fog”. I find that the trans_raster3d helps somewhat, but is still not infallible.
