Internally represented as a list of convex polygons. The number of polygons is limited to 256.
To avoid duplicating data when you have several instances of a particular mesh positioned differently, you do not use this class to represent a convex object directly. Instead, you create an instance of this mesh via the PxConvexMeshGeometry and PxShape classes.
To create an instance of this class call PxPhysics::createConvexMesh(), and PxConvexMesh::release() to delete it. This is only possible once you have released all of its PxShape instances.

| virtual PX_PHYSX_COMMON_API void PxConvexMesh::acquireReference | ( | ) | [pure virtual] |
Acquires a counted reference to a convex mesh.
This method increases the reference count of the convex mesh by 1. Decrement the reference count by calling release()
| virtual PX_PHYSX_COMMON_API const char* PxConvexMesh::getConcreteTypeName | ( | ) | const [inline, virtual] |

| PxVec3 & | localCenterOfMass | |||
| ) | const [pure virtual] |
Returns the mass properties of the mesh assuming unit density.
The following relationship holds between mass and volume:
mass = volume * density
The mass of a unit density mesh is equal to its volume, so this function returns the volume of the mesh.
Similarly, to obtain the localInertia of an identically shaped object with a uniform density of d, simply multiply the localInertia of the unit density mesh by d.
| [out] | mass | The mass of the mesh assuming unit density. |
| [out] | localInertia | The inertia tensor in mesh local space assuming unit density. |
| [out] | localCenterOfMass | Position of center of mass (or centroid) in mesh local space. |

| virtual PX_PHYSX_COMMON_API PxU32 PxConvexMesh::getReferenceCount | ( | ) | const [pure virtual] |
Returns the reference count of a convex mesh.
At creation, the reference count of the convex mesh is 1. Every shape referencing this convex mesh increments the count by 1. When the reference count reaches 0, and only then, the convex mesh gets destroyed automatically.

If the total number of vertices are more than 64 or any number of vertices in a polygon is more than 32, or convex hull data was not cooked with GPU data enabled during cooking or was loaded from a serialized collection, the convex hull is incompatible with GPU collision detection.
