C# Class R3.Geometry.Slicer

Public Methods

Method	Description
Clip ( List &tiles, Circle c, bool keepInside ) : void	Clip the drawn polygons in a set of tiles, using a circle.
SlicePolygon ( Polygon p, Circle c, List &output ) : bool	Slices up a polygon with a circle (line case not supported). The input polygon might get reversed
SlicePolygon ( Polygon p, CircleNE c, Geometry g, double thickness, List &output ) : void	Slices a polygon by a circle with some thickness. Input circle may be a line. The input polygon might get reversed

Method	Description
GetNextSegmentIndex ( Polygon walking, int idx ) : int
GetPairPoints ( List iPoints, int pair, bool increment, IntersectionPoint &iPoint1, IntersectionPoint &iPoint2 ) : void	Get a pair of intersection points.
SlicePolygonInternal ( Polygon p, Circle c, List &output ) : bool
SmallerSplicedArc ( Circle c, List iPoints, int &pair, bool increment, int &nextSegIndex ) : Segment	Helper to return the smaller spliced arc.
SplicedArc ( Polygon parent, Circle c, List iPoints, int &pair, bool increment, int &nextSegIndex ) : Segment	Helper to return a spliced arc.
SplitHelper ( Segment segmentToSplit, Vector3D iLocation, Polygon diced, List iPoints ) : Segment	Splits segmentToSplit in two based on iLocation. First new segment will be added to diced, and second new segment will be returned. If split doesn't happen, segmentToSplit will be returned.
WalkPolygon ( Polygon parent, Polygon walking, Circle c, int pair, List iPoints, bool increment ) : Polygon	Helper to walk a polygon, starting from a pair of intersection points. increment determines the direction we are walking. NOTE: when walking from i1 -> i2 along c, we should be moving through the interior of the polygon.

Clip the drawn polygons in a set of tiles, using a circle.
