Virtual methods were used in the `MeshConnectivity` classes for the internal ray casting system. However, using virtual methods in the execution environment is being deprecated. This change replaces the virtual object with an object containing a `Variant`. The `Variant` holds one of the supported mesh connectivities and selects the correct one at runtime rather than jumping into a virtual method.
