How to best find adjacent convex hulls

[seanm92]

Hello all,

I've been trying to improve the ConvexDecompositionDemoEx by adding connectivity to the btCompoundShape. The problem I have is that I can't seem to find a good way to test if btConvexHullShapes are adjacent/touching each another. I've tried using btCollisionShape::getBoundingSphere but it seems to be too inaccurate. Any ideas would be appreciated.

Cheers,
Sean

Ok so it seems that my bounding spheres are completely incorrect for each btConvexHullShape within a btCompoundShape (see picture.. the pink is a building and the green are the bounding spheres). What is fastest way to calculate bounding spheres?

Cheers,

max(distance to each vertex from objectspace 0,0,0)

and add on the collision margin
