[Paraview] File format for primatives

[Stephen Sintay]

I am looking for a file format that will support input of primitives 
such as sphere. The VRMl2 (*.wrl) format appears to support this, but 
this format is superceeded by X3D and I am having difficulty finding 
documentation for the old format. Their does not appear to be a paraview 
reader for X3D.

Are there other file formats that will support primitives? Sphere, cube, 
cone, etc... Or does anyone know where to find some documentation for 
the VRML2 file format that paraview has a reader for?

Thanks

Steve
