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
