Intersection contour
Is it possible to display only the points that two or more 3d objects
have in common? For example, I have a plane intersecting a sphere and want to show only the circle representing the points that both have in common.

Hi Jerry,
There is no built-in way to do this. This could probably be accomplished through a plugin, but I'm still not exactly sure what you want. Do you have some sample screenshot of the effect you are referring to?

I think Jerry is looking for the intersection of two meshes. It's easy for primitives like [ sphere & plane ], but can get pretty tricky when the meshes are more complicated.
Pictured here is [ sphere & cube ] and the contour is already getting to be a strange shape. If either mesh is not manifold (would leak water), then the intersection space is no longer manifold either.  Except in the most trivial cases, it's not something you can/should try to do in real time with moving objects. However, there are sometimes some interesting z-buffer tricks which can emulate this kind of work in limited scenarios. Last edited by halley; 03-11-2006 at 08:32 AM.
