Hello,everybody!!

I want to use vtkPicker and vtkRenderWindowInteractor to interact each other.
That is,I display an 3D object in RenderWindow,and I am eage to interact with it, utilize the mouse to pick two point on the object and obtain their coordinate value and data,connect them with a line.

How to realize it?
