convex hull in maya?

malcolm

Hey I'm looking for a way to create convex hulls for collision in maya. We have havoc but their tool is really bad, no real time editing. Anyone got a convex hull solution in maya?

As far as I know the latest or any version I have seen for Havoc content tools in both max and maya, convex hull is on by default. You have to make sure you add "Ridged Body" to your collision model first before you can change the collision type (IE. Mesh, Box, Convex etc..).

Sorry, what I meant was we have to build collision volumes for our props and I'm looking for a quick way to generate a convex hull ideally by selecting verts on a model in maya. Havok comes with an auto generate convex hull from selected model but you can't add or subtract verts once the hull is generated you have to delete it and generate a new one to changes the verts it uses.

I think there's a maya plugin for PhysX that might be usefull..... Not 100% sure, but might be worth checking out.

I'd be interested in something like this for max, if anyone knows of anything...

If you're up to the scripting, this algorithm works great:

Unfortunately I can't share my implementation.
