Hi. I want to show a colored point cloud (vtkPointSet) returning from a custom filter. In my custom filter, I prepare the pointCloud in this way:
vtkSmartPointer<vtkPointSet> pointCloud = vtkSmartPointer<vtkPolyData>::New(); pointCloud->SetPoints(points); pointCloud->GetPointData()->SetScalars(distances); pointCloud->Update(); output->DeepCopy(pointCloud); points is a vtkPoints and distances is a vtkDoubleArray. The problem is that nothing is showing. If instead of using a vtkPointSet I use a vtkPolyData and filter it with a vtkDelaunay2D, it shows some points, but other points are left out (Do you know why is this happening?). If I use a vtkDelaunay3D, again, I see nothing. Do you know why is this happening? What do you recommend to build point clouds? I would really appreciate any suggestion. Thanks in advance, Federico
