Coordinate System and eye

Hi Bill,

I've got one question about Coordinate System in VisAD. What is the link
between the coordinate system of the samples and the coordinate system
of Java3d ? In fact, my question is "how to locate the centered eye ?"
If I use :

Canvas3D canvas = disp_rend.getCanvas();
Point3d eye_position = new Point3d();

I got {0,0,0}.
Is there a method that gives the eye position in the same coordinate
system as the samples ?

Thanks in advance
