[vtkusers] displaying 3D on the web

[Sebastien Jourdain]

Hi Ayman,

I'm surprised that the VRML importer didn't worked.
Did you linked it to an existing RenderWindow ?
Did you called Update on it ?
The Importer can not work alone, you have to provide a render window
that will be filled by the vrml file once the Update method is called
on it. Moreover, once you have the actor you can go to the mapper and
then to the dataset.

For X3D, you should check http://forge.collaviz.org/community/xiot and
maybe directly contact Kristian Sons. I know that he has done an X3D
importer for VTK.
