[vtkusers] How to use vtkVRMLImporter?

[Scheurer, Christian]

Hello Everybody,

i want to use vtkVRMLImporter to import normal VRML files and display the 3D model (here a point cloud).
The VRML files i use do not have any DEF nodes, so i cannot use 

vtkObject *GetVRMLDEFObject (const char *name)

and cast to vtkPoints!

Does anybody has an idea how to use the following functions?

void enterNode (const char *)
void exitNode ()
void enterField (const char *)
void exitField ()
void useNode (const char *)

Can i use these functions to get the point coordinates from the vrml files?

Best Regards,
Christian
