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 (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).

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

Member Function Documentation

static vtkVRMLImporter* vtkVRMLImporter::New ( ) [static]

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

Reimplemented from vtkObject.

virtual const char* vtkVRMLImporter::GetClassName ( ) [virtual]

Reimplemented from vtkImporter.

static int vtkVRMLImporter::IsTypeOf ( const char * name ) [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.

virtual int vtkVRMLImporter::IsA ( const char * name ) [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.

static vtkVRMLImporter* vtkVRMLImporter::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkImporter.

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.

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.
