[vtkusers] vtkCatmullClarkFilter HELP PLEASE!!

[minococciolo at libero.it]

Hello everybody,
I'm trying to use vtkCatmullClarkFilter to create a 
quadrangular mesh.
Unfortunately, the documentation about it on the web is 
quite null. Is there someone who can help me? 
I'm using C++ with Visual C++ 
Express 2005, but every example or source code in tcl, python etc. is good.

Thank you very much.

#include....

int main(int argc, char** argv)
{
	// First we'll 
create some points.
	//
	vtkPoints *points = vtkPoints::New();
	points-
>InsertPoint(0, 0.0, 0.0, 0.0);
	points->InsertPoint(1, 0.0, 1.0, 0.0);
	points-
>InsertPoint(2, 1.0, 1.0, 0.0);
	points->InsertPoint(3, 1.0, 0.0, 0.0);


vtkCellArray *strips = vtkCellArray::New();
	strips->InsertNextCell(4);
	strips-
>InsertCellPoint(0);
	strips->InsertCellPoint(1);
	strips->InsertCellPoint(2);
	
strips->InsertCellPoint(3);

vtkPolyData *profile = vtkPolyData::New();
	
profile->SetPoints(points);
	profile->SetPolys(strips);

*cc = vtkCatmullClarkFilter::New();
	cc->SetNumberOfSubdivisions(4);

	vtkPolyDataMapper *map = 
vtkPolyDataMapper::New();
	map->SetInput(cc->GetOutput());
	
	vtkActor *strip = 
vtkActor::New();
	strip->SetMapper(map);
	strip->GetProperty()->SetColor

	// Create the usual rendering stuff.

	vtkRenderWindow *renWin = vtkRenderWindow::New();
	
renWin->AddRenderer(ren1);
	vtkRenderWindowInteractor *iren = 
vtkRenderWindowInteractor::New();
	iren->SetRenderWindow(renWin);

	// Add the 
actors to the renderer, set the background and size
	//
