Hi Peer, ok I see now - I had previously thought the rays would start at the camera point and go forward. You may need them to be a little longer if they're starting behind the camera point. Also the factory system may not be expecting to have a factory call both calculate() and also be used with update()/commit() as well with the same factory.

Does the attached version work any better for you?

Michael,

Thanks for teaching me that calculate() and commit() shouldn't be used on the same factory and for showing how to add the factory output to the geometryDatabase in another way.
