SpatialExtensionsDirectionUnitVectorSmooth Method

Finds the local reach direction as the direction from the locally surrounding digi points. The vector returned is a unit vector.

This returns a smoothly varying unit vector: On the center of the line between two digipoints, the direction of the line is returned. On a digipoint the average of the line before and after the digipoint is returned. In between the center of the line and the digipoint the direction varies linearly.
