[vtkusers] Re : vtkMultiBlockDataSet and SetInputConnection

[R M]

Hi,

I had seen the vtkCompositeDataGeometryFilter but, the problem in my case, is that the ouput is one polydata (so one polydatamapper and one actor). And, I want the option to make visible or not one of the block on my geometry. That 's why I haven't use vtkCompositeDataGeometryFilter.

Thank you.

Here is what I have been using for several years.

eb1 is my multi-block dataset.

VTK_CREATE(vtkCompositeDataGeometryFilter, geom1);
geom1->SetInputConnection(0, eb1->GetOutputPort(0));
geom1->Update();

VTK_CREATE(vtkPolyDataMapper, mapper1);
mapper1->SetInputConnection(geom1->GetOutputPort(0));

VTK_CREATE(vtkActor, actor1);
actor1->SetMapper(mapper1);
