Can a simple viewshed analysis be done with a projector?

I am looking to do a simple viewshed analysis and I’m wondering if a projector can be used for this. I would like the projector to project a color or light on to the terrain and buildings. The problem is projectors do not occlude behind geometry but instead go straight through. Is there a shader that I can use that will take into account occlusion of objects and terrain?

Ah, ok, I think we have different ideas of what a viewshed looks like :slight_smile: What you’re describing looks more like the effect in games such as Monaco. Does this help?: Facebook
