[vtkusers] Re: Example Medical3 doesnt run

[Pedro Patron]

I've be able to make it runs this way:

	vtkImageDataGeometryFilter *saggitalSection = 	
vtkImageDataGeometryFilter::New();
	saggitalSection->SetExtent(32, 32, 0, 63, 0, 92);
	saggitalSection->SetInput(v16->GetOutput());

	vtkPolyDataMapper *saggitalMapper = vtkPolyDataMapper::New();
	saggitalMapper->SetInput(saggitalSection->GetOutput());
	//saggitalMapper->ScalarsVisibleOn();
	saggitalMapper->SetScalarRange(0,2000);
	saggitalMapper->SetLookupTable(bwLut);

	vtkActor * saggital = vtkActor::New();
	saggital->SetMapper(saggitalMapper);

Instead of the original:

	vtkImageMapToColors *saggitalColors = vtkImageMapToColors::New();
	saggitalColors->SetInput(v16->GetOutput());
	saggitalColors->SetLookupTable(bwLut);

	vtkImageActor *saggital = vtkImageActor::New();
	saggital->SetInput(saggitalColors->GetOutput());
	saggital->SetDisplayExtent(32,32, 0,63, 0,92);

Does anyone know the problem with the second form?
How is the better way to do it?

Thank you in advance.
