How to create 3D (XYZ) plane using Java 3d

[anil]

Hi all,
          I want to create 3D plane, having X, Y and Z axis, so that I can place an object on this 3D plane. Can any one give me some sample examples or some ideas.
          The object can be placed in X-Y plane (i.e. ground represented with gray color). The sky should be displayed with blue color.
          Any inputs on this will be of great help.

          Thanks in advance.

Regards
Anil

I'm not sure what u mean but u can use parametric representation for a plane and try to draw it with GeometryArray class
