Hi John, > I run VisAD on Mac OS X and it worked great, until I upgraded to OS X 10.1. > Now, the graphics appear distorted.

I've installed VisAD on a Mac OS X system and tried many of the test examples. Without the Java3D extension, most of the VisAD examples won't run, but VisAD seemed to work for the Java2D examples. However, the simple 2D plot from Ugo Taddei's tutorial: http://www.ssec.wisc.edu/~billh/tutorial/s1/P1_01.java produced an incorrect plot under the previous Mac OS X release, due to some bug in the Mac Java implementation that I never isolated. I just installed the new Mac OS X 10.1 release and Developer Tools, and noticed that the problem is still there. I'd like to make this independent of VisAD for a bug report to Apple, but that requires some work ... I've also tried Unidata's GDV application using the WebStart application now available with Mac OS X, and although the download worked fine, there are still problems with even the Java2D part of GDV on the MacOS version of JDK 1.3.1, starting with re-draws not being done when needed. I don't know yet whether the problem is in GDV or the MacOS JDK 1.3.1. Incidentally, things are looking up for Java3D on Mac OS X, since Apple hired Gerard Ziemski, the programmer responsible for porting GL4Java for Mac OS X. --Russ _____________________________________________________________________ Russ Rew UCAR Unidata Program russ@xxxxxxxxxxxxxxxx http://www.unidata.ucar.edu
