```
SoObjectToSegmentApproximation2d engine. The SoObjectToSegmentApproximation2d engine computes the polygonal approximation of object boundaries.
For an introduction, see section Discrete Geometry.
The SoObjectToSegmentApproximation2d engine first extracts chains from objects edges. Then it applies the dichotomous polygonal approximation. This operation consists in converting chains into segments by approximating the polygons of linear segments. It provides the outlines of the polygons.
