updating a geometry does explicitly support changing the number of triangles, so an object might start with a plane surface and later grow a pyramid. The updateVerices etc functions are all written to check the number of data points and reallocate if there was a change. Dependent data (faceNormalData, _vertexNormals) remain the same and cause an error.
