Highlighting areas of an object in contact with another?
Hey all. First time posting yet a long-time lurker on here.
No point in babbling, onto the question. I'm wondering how you would highlight on an object — a sphere for example — the areas that are touching other objects. To further the sphere example, let's assume there's a plane as well. So the sphere is placed a bit off center along the horizontal plane. What I'd want is for the outsides of the sphere to be highlighted, and given a special glow-y texture of some sort.
This has just been one little trouble I've had while I've been thinking through the next step for a small project I've been working on.
I appreciate any help, and if you need me to clarify my example (it made sense in my head!) feel free to ask.
Thanks much.

You can iterate through the points of contact in a collision situation and draw those, they're a member of the Collision object passed to the OnCollisionEnter etc...
