Detailed Description

imports VRML 2.0 files.

vtkVRMLImporter imports VRML 2.0 files into VTK.

Warning: These nodes are currently supported: Appearance IndexedFaceSet Box IndexedLineSet Color Material Cone Shape Coordinate Sphere Cylinder Transform DirectionalLight; As you can see this implementation focuses on getting the geometry translated. The routes and scripting nodes are ignored since they deal with directly accessing a nodes internal structure based on the VRML spec. Since this is a translation the internal data structures differ greatly from the VRML spec and the External Authoring Interface (see the VRML spec). The DEF/USE mechanism does allow the VTK user to extract objects from the scene and directly manipulate them using the native language (Python, Java, or whatever language VTK is wrapped in). This, in a way, removes the need for the route and script mechanism (not completely though). Texture coordinates are attached to the mesh is available but image textures are not loaded. Viewpoints (camera presets) are not imported.

Thanks:: Thanks to Russ Coucher of Areva for numerous bug fixes and a new test.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImporter.

virtual void vtkVRMLImporter::SetFileName ( const char * )

virtual

Specify the name of the file to read.

virtual char* vtkVRMLImporter::GetFileName ( )

virtual

Specify the name of the file to read.

virtual void vtkVRMLImporter::SetShapeResolution ( int )

virtual

Specify the resolution for Sphere, Cone and Cylinder shape sources.

Default is 12.

virtual int vtkVRMLImporter::GetShapeResolution ( )

virtual

Specify the resolution for Sphere, Cone and Cylinder shape sources.

Default is 12.

vtkObject* vtkVRMLImporter::GetVRMLDEFObject ( const char * name )

In the VRML spec you can DEF and USE nodes (name them), This routine will return the associated VTK object which was created as a result of the DEF mechanism Send in the name from the VRML file, get the VTK object.

You will have to check and correctly cast the object since this only returns vtkObjects.
