The ghosting effect (where the back parts do not show but you can see through a figure or prop) is easily done. You make it invisible to raytracing and you refract to reveal what is behind. This was documented at RDNA years ago.

What you seek here with vertical lines that are straight and parallel and even with respect to the camera by applying something to a 3D model is not possible, though. Not with lights, and not with a shader alone.

Even if I could figure out how to do it (and I probably can't), is it worth the effort? Why not render the figure into an animation, then load the animation into a movie and make raster lines using math nodes, applied to the movie node. That would be very easy - similar to the TV raster lines I did with my artistic lens.

The difference here, why you cannot use the artistic lens, is you want it to only apply to part of the scene - the part occupied by the 3D figure. That's why it is really not possible using tricks I've published before. The lines would have to be generated on the lens - where the line is there, you would have to "see" the subject, and where the the line is not there (in a gap) you would have to "see through" the subject. With no access to internals I can't think of a way to do that.

If, on the other hand, you're OK with the lines not being straight, parallel, and even with respect to the camera, but rather with respect to some arbitrary orientation plane, then this is not so hard.


Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
