This function adds and returns a new surface on a model.
Returns a new shape.
A polymesh shape will collide with other objects, but does not move, i.e. it will react as if the mass is zero. If you want to create a shape from a surface that is physically reactive, use the Shape::ConvexHull() or Shape::ConvexDecomposition() functions.
