Hi evrey one,
I am on vtk 8.2, and I try on a 3d view (perspective enable) to zoom with wheel mouse on the current cursor position.
For zooming I am using the Dolly function from vtkCamera.
I’am zooming then I apply a translation to my camera director vector (postion, focal) to set the camera at the attended postion.
But the result is not good, I think this is not th good way. If some one as an idea.
