[vtkusers] About Visualization of 3D points

[Rong Xu]

Hi,

I encountered a problem about the visualization of 3D points. I read a *.stl
file and got a vtkPolyData. Then I can use vtkPolyDataMapper, vtkActor,
vtkRenderer, vtkRenderWindow, and vtkRenderWindowInteractor to visualize a
3D surface from that *.stl file.

Another idea I want to just visualize 3D points from vtkPolyData. I know I
can use the method vtkPolyData::GetPoints() to get 3D points. But I don't to
how to visualize these vtkPoints. Does anyone give me an example or advice
for this problem?

I will appreciate for your help ! Thank you!
