CSG_Lines CSG_Shape_Polygon_Part::Get_Shared_Edges	(	CSG_Shape_Polygon_Part *	pPart,
		bool	bVertexCheck,
		double	Epsilon = `0.`
	)

Returns all edge segments shared by this polygon part and the one provide by pPart argument as CSG_Lines object. If bVertexCheck is true vertices lying on edged segments of the other polygon part will be recognized. If not only vertices are taken into respect that are shared by both polygon parts. Due to precision issues the tolerance factor specified with Epsilon should be slightly greater than zero when using the bVertexCheck option.

double CSG_Shape_Polygon_Part::Get_Shared_Length	(	CSG_Shape_Polygon_Part *	pPart,

This function requests the edges shared by this polygon part and the one provided by the pPart argument and returns the total length. See Get_Shared_Edges() for more details.

◆ is_Neighbour()

bool CSG_Shape_Polygon_Part::is_Neighbour	(	CSG_Shape_Polygon_Part *	pPart,
		bool	bSimpleCheck = `true`
	)

Returns true if this polygon part touches that defined by pPart, i.e. the polygons share vertices or have vertices placed on the edge of the other. If bSimpleCheck is true the check is only performed until one shared vertex is found, which is sufficient if it can be expected that the polygons do not overlap.
