hidden surfaces

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,

There is a clever trick with vwrays that can do exactly that. John m posted a tech note on this on his website. Google arbitrary cliping planes and vwrays, I'll bet you find it. Not going to try it on this stupid little iPhone keyboard...

I've moved over to Dokuwiki and the old links are probably stale. You'll find it here:
