RescalePointArray


Header: FIL.h
Namespace: fil
Module: FoundationLite

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

Syntax

C++
C#
 
void fil::RescalePointArray
(
	const ftl::Array<fil::Point2D>& inPoints,
	ftl::Optional<const fil::Point2D&> inReferencePoint,
	float inScale,
	bool inInverse,
	ftl::Array<fil::Point2D>& outPoints
)

Parameters

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

In-place Processing

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