white_dune is a graphical VRML97/X3D editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development.

With white_dune you can create/change 3D objects and animate them (in a easy way if you choose the -4kids GUI).
The result can be shown in any webgl enabled web browser or can be converted to the RIB format for movie creation.
