RescalePointArray

Header:	AVL.h
Namespace:	avl

Changes the distances of points from an array to a reference point.

Syntax

void avl::RescalePointArray
(
	const atl::Array<avl::Point2D>& inPoints,
	atl::Optional<const avl::Point2D&> inReferencePoint,
	float inScale,
	bool inInverse,
	atl::Array<avl::Point2D>& outPoints
)

Parameters

Name	Type	Default	Description
inPoints	const Array<Point2D>&
inReferencePoint	Optional<const Point2D&>	NIL	Point to which the distances will be changed (the mass center by default)
inScale	float	1.0f	Scaling factor
inInverse	bool		Switches to the inverse operation
outPoints	Array<Point2D>&

In-place Processing

This function supports in-place data processing - you can pass the same reference to inPoints and outPoints

Errors
