This is tricky to explain, so hopefully the images explains it better. They are mock ups of my idea in 2D and 3D respectively.
I would like to visualize how an object blocks the “emission” of another. I would however like this blocking to be visualized along the “emission path” of the other object. You can then see what straight paths are available within the “emitting” object from a point source imagined in its center to its boundaries. Oh, and I also would like this to be dynamic - so I can move the “emitting” object.
Now, I’m open for any and all suggestions. 2D, 3D, maybe some clever use of light sources and just have them shadow some other object. Is this doable?
