PxComputeHullPolygons

Defined in include/cooking/PxCooking.h

bool PxComputeHullPolygons(const physx::PxCookingParams &params, const physx::PxSimpleTriangleMesh &mesh, physx::PxAllocatorCallback &inCallback, physx::PxU32 &nbVerts, physx::PxVec3 *&vertices, physx::PxU32 &nbIndices, physx::PxU32 *&indices, physx::PxU32 &nbPolygons, physx::PxHullPolygon *&hullPolygons)

Compute hull polygons from given vertices and triangles.

Polygons are needed for PxConvexMeshDesc rather than triangles.

Please note that the resulting polygons may have different number of vertices. Some vertices may be removed. The output vertices, indices and polygons must be used to construct a hull.

The provided PxAllocatorCallback does allocate the out arrays. It is the user responsibility to deallocated those arrays.
