Hi Kevin, Congrats! You have found a bug vintage 1990, in Vis5D code that we ported from C to Java for VisAD. Probably the oldest bug fixed yet for VisAD. It lingered so long because it was masked by the behavior of graphics libraries (as you noted, it only manifest with recent versions of Java3D), and by the general wierdness of transparency. The fix is in the *.jar files at: ftp://ftp.ssec.wisc.edu/pub/visad-2.0/untested/ Thanks, Bill
