Hi Brad, I can run Java3D applications remotely with Xwindows. I used SUN
Machines running some version of Solaris with JDK1.2 (but neither OpenGL
nor Java3D) and my Linux laptop with JDK1.2.2RC4, Java3d, and MesaGL. It
worked without a hitch, but the performance (for animation) was really
horrid.
Are you sure you enabled xforwarding properly?
