I’m trying to make a disco ball. I don’t care as much about the appearance of the disco ball itself (though it would be nice if you could tell it was a disco ball), but I would like it to have the correct effect on the scene (pieces of light dancing around the room.) Here’s an example:
I don’t really know where to begin, but I figured I’d try first to do it like in real life: a mirrored UV sphere with a spot lamp shining on it.
I’ve been able to make the ball reflect its surroundings, but unable to have it “shoot” the light rays off in different directions.
I looked into caustics a little bit, because I thought that might be the correct thing to use, but have come to the conclusion that Blender 2.48a Internal cannot do caustics. I’m going to experiment with YafRay to see if I can get some caustics going.
Am I on the right path? Does anyone know how I can achieve the desired effect? Thanks!
