<div>I have select the world coordinate of a point in the object
which I read from a STL file. Now I want to place a point to represent
the point that I have selected when I click mouse button. But I have no idea how
to do this. Is vtkPointWidget ok? Or something else? Please give me some advice.
Thank you for your attention! </div>
