Method createConvexMesh

src/engine/PhysicsCommon.cpp:607–629

Create a convex mesh from a PolygonVertexArray describing vertices and faces The data (vertices, faces indices, ...) are copied from the PolygonVertexArray into the created ConvexMesh. * @param polygonVertexArray A pointer to the polygon vertex array to use to create the convex mesh * @param messages A reference to a vector of messages. This vector might contains errors that occured during the cr

 * @return A pointer to the created ConvexMesh instance or nullptr if errors occured during the creation
