 By picking the *source mesh* in the object list, and den selecting **Object|Create colored mesh**, one obtains a colorization of the mesh that describes the magnitude of the changes by color intensity. Red indicates a movement against the direction of the surface normal, and blue a movement in the direction of the surface normal. Note, that depending on the approach used to create the surface, the normal vectors might point outward or inward.
