PolylineMath3DGetFractionalEndIndexOfPolylineWithCapInsetAbsolute(IListPointD3D, Double, Boolean, Boolean, PolylinePointD3DAsClass) Method

Gets the fractional end index of a polyline with an end cap when given the absolute inset of the end cap.

Namespace: Altaxo.Geometry
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3179.0 (4.8.3179.0)
Syntax
C#
Copy
public static double GetFractionalEndIndexOfPolylineWithCapInsetAbsolute(
	IList<PointD3D> polylinePoints,
	double capInsetAbsolute,
	out bool endCapForwardAndPositionProvided,
	out bool endCapNeedsJoiningSegment,
	PolylinePointD3DAsClass endCapCOS
)

Parameters

polylinePoints  IListPointD3D
The polyline points.
capInsetAbsolute  Double
The absolute cap inset. Must be a value >= 0.
endCapForwardAndPositionProvided  Boolean
On return, if this value is true, the position and forward vector of the end cap was calculated and is returned in endCapCOS (but not the west and north vectors).
endCapNeedsJoiningSegment  Boolean
On return, if this value is true, the end cap needs a joining segment with the same direction as the start cap to seamlessly merge with the last line segment.
endCapCOS  PolylinePointD3DAsClass
On return, if endCapForwardAndPositionProvided is true, this value holds the position and forward vector of the end cap (but not the west and north vectors).

Return Value

Double
The fractional end index. A value of polylinePoints.Count-1 indicate that the new polyline should end at the original polyline end, a value of e.g. polylinePoints.Count-1.5 indicate that it should end in the middle between the next-to-last and last point, and so on.
