The modifier keeps the rest of the anchor vertices in fixed positions, and calculates the best possible locations of all the remaining vertices to preserve the original geometric details.<br /> <br /> <br /> This modifier captures the geometric details with the uses of differential coordinates. The differential coordinates captures the local geometric information how curvature and direction of a vertex based on its neighbors.<br /> <br /> <br /> {{Note<br /> |1=Note<br /> |2=You must define a {{Literal|Anchors Vertex Group}}.

The objective of the system is to find the rotation of the differential coordinates preserving the best possible geometric detail. The system retains details better if more repetitions are used.
