This is a continuation of a post I made yesterday. I have a lense (now not
hollow, thanks to the help I got here!), and it refracts light headed
towards the camera fine. For example, a scene is distorted when the camera
looks through it. But what I really want the lense for is to split up a
beam of light. I am trying to use a spotlight or cylindrical light, but
when they pass through the lense they are unaffected. I have tried the
caustics keyword, but it does not seem to do anything. I am wondering if
only area or point lights are affected by lenses because of some wierd way
that the spot and cylinder lights work. Is this true? The reason I ask is
that I need to simulate a fanned laser for a presentation I am doing on
structured light vision. Thank you so much... again.
