Hi Peter,
I run your program under Solaris and Win2K with latest
Nvidia driver and the upcoming J3D v1.3 release.
The result show it works fine under
(i) Solaris
(ii) Win2K J3D OpenGL version
(iii) Win2K J3D DirectX version in emulation mode
(java -Dj3d.d3ddevice=reference ModelClipTest
if you have DirectX 8.1 SDK install in your system)
But fail under
(iv) Win2K J3D DirectX version in hardware mode.
This suggest it is a driver bug.
