RescaleSegment3D

Header:	FIL.h
Namespace:	fil

Lengthens or shortens a segment in 3D relatively.

Syntax

void fil::RescaleSegment3D
(
	const fil::Segment3D& inSegment3D,
	ftl::Optional<const fil::Point3D&> inReferencePoint,
	float inScale,
	bool inInverse,
	fil::Segment3D& outSegment3D
)

Parameters

Name	Type	Default	Description
inSegment3D	const Segment3D&		Input segment in 3D
inReferencePoint	Optional<const Point3D&>	NIL	The point to which all distances change linearly (the mass center by default)
inScale	float	1.0f	Scaling factor (negative values invert the segment)
inInverse	bool		Switches to the inverse operation
outSegment3D	Segment3D&

Errors
