[vtkusers] Loading VRML file into a vtkActor

[Vidyadhar]

Hi,
vtkPolyData does not store those material properties. Coloring and shading information is part of the vtkProperty associated with vtkActor which you can access in similar fashion.

  Thanks Vidyadhar. Does the vtkPolydata we get by doing this retain the coloring and shading information present in the original 3DS model?

    Hi,
    Both importers have GetRenderer methods which give access to renderer. From that you can retrieve vtkActorCollection. Traverse the collection to retrieve each actor. From actor you can retrieve its mapper (some polydata mapper) and from mapper get its input which will be the polydata mesh. I have not use this with vtkVRMLImporter but with vtk3DSImporter.

      Hi All,

      I tried out the vtkVRMLImporter test. I want to be able to load a VRML file, change its visibility, and move it around. Is there a way to get the output of the importer into a polydatamapper and then into an actor? I tried doing this with 3DS files too using vtk3DSImporter but was unsuccessful. 

      Any help would be greatly appreciated.

      Shriram
