CreateCoordinateSystemFromTwoPoints


Header: AVL.h
Namespace: avl

Creates a coordinate system with two points on its axes.

Applications: Most often used to define an object alignment from results of two 1D Edge Detection scans, each of which locates one side of a rectangular object.

Syntax

void avl::CreateCoordinateSystemFromTwoPoints
(
	const avl::Point2D& inPoint1,
	const avl::Point2D& inPoint2,
	float inAngle,
	float inScale,
	float inScaleDivisor,
	avl::CoordinateSystem2D& outCoordinateSystem
)

Parameters

Name Type Range Default Description
Input value
 inPoint1 const Point2D&
Input value
 inPoint2 const Point2D&
Input value
 inAngle float
Input value
 inScale float 0.001 - 1.0f
Input value
 inScaleDivisor float 0.001 - 1.0f
Output value
 outCoordinateSystem CoordinateSystem2D&

Hints

  • PassinPoint1 and inPoint2 to computed points lying on (respectively) the X and the Y axes of a new coordinate system.
  • Optionally set inAngle to define the rotation.
  • Optionally set inScale and inScaleDivisor to obtain a custom scale.
