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
Warning:
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 (Tcl, 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).

Member Function Documentation

void vtkVRMLImporter::enterNode const char *   
 

Needed by the yacc/lex grammar used

virtual const char* vtkVRMLImporter::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImporter.

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.

virtual int vtkVRMLImporter::IsA const char *    type [virtual]
 

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.

Reimplemented from vtkImporter.

int vtkVRMLImporter::IsTypeOf const char *    type [static]
 

Return 1 if this class type 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.

Reimplemented from vtkImporter.

vtkVRMLImporter* vtkVRMLImporter::New   [inline, static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

void vtkVRMLImporter::PrintSelf ostream &    os,
vtkIndent    indent
[virtual]
 

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.

vtkVRMLImporter* vtkVRMLImporter::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImporter.
