[Radiance-general] hidden surfaces

[Dave Bosworth]

Hello All - 

I'm wondering if anyone knows a clever way to allow surfaces to contribute to a rendering, but not appear in the final view.  That is, instead of using a clipping plane, is there a means to "hide" specific surfaces?  I need to pull off certain surfaces and look into the room, but the plan is sort of squiggley, and a simple cutting plane doesn't do a very good job.

thank you,
