Cut a circle hole interactively

[Thanatossan]

I try interactive cut a circle hole in the mesh that depends on camera angle like this example https://github.com/marcomusy/vedo/blob/master/examples/basic/cut_freehand.py

except, I want to only click once (not draw a spline) and create a circle around the cursor to cut the mesh.

I tried to create a cylinder and had a problem with the axis of the cylinder doesn't align well with the camera angle.

Would you please give me an idea, of how to achieve this in Vedo?

Hi you can get the camera angle and create a cylinder from

        poc = np.array(plt.camera.GetPosition())
        foc = np.array(plt.camera.GetFocalPoint())
        cyl = Tube([poc, foc])
