在VTK中从2D标签到3D空间中的一个点画一条线

Question

I am working with 3D visualisation using VTK. I would like a attach a line between a point in 3D space to fixed label (in 2D space) on VTKRenderWindow.

I have no idea what possibly I can do. Any hint on that would be much appreciated.

If someone has worked with Polyworks than it would be exactly something like that.

Answer 1

One possibility is to use a vtkFollower object and vtkFollower.SetCamera(vtkCamera) (see here ).
