I went back to the versions I tried before when upgrading to a Windows 10 box, which are
jogamp-java3d-1.7.0-final 2020-01-25
jogamp-fat-all-2.4.0 rc 20200202

I also went back to the versions that were working on the old Windows 7 box, which were
jogamp 2.3.2
java3d 1.6.0

Neither of these configurations works on the Windows 10 box (both were Dells).  Same symptoms, extremely slow, as if there is some sort of busy wait or contention going on.  The fact that the exact set of libraries (including the same Java jre) that work on the Windows 7 box don't work on the Windows 10 box suggests it is something about the Windows 10 Dell with Intel HD Graphics 4000.  The fact that the simple com.jogamp.opengl test does work suggests it's at a higher level than that.

Can anyone point to online javadoc for JCanvas3D or an example of its use?  I am using this with swing, maybe that might make a difference.

Any other suggestions for things to try are appreciated.
