    Make sure to also watch this similar method: kzread.info/dash/bejne/qpqmxcltmcu1lrA.html

    You could also use @P = fromNDC(cam,@P) after setting P.z to a distance value of let's say 2.0. Then the silhouette is transformed back into the camera view having a distance of 2.0 from your camera. No need for the aspect correction afterwards, though. :)

    cool, something like projection on screen. This is cleanest method I ever seen. Is there a way to make cuts on a geometry using texture? I mean not subdivided geometry that we could vertex split, but single triangle for example?

    cool! this method does run into some issues with complex meshes, triangulate 2d can fail. also have to handle edge cases for holes

    Yes, you are correct. The hole SOP can perhaps handle inside holes. If triangulating causes problems, you could look into transfering the distance to the flattened mesh to a new grid and do the cutting there.
