CreateCoordinateSystemFromTwoPoints


Creates a coordinate system with two points on its axes.

Syntax

C++
C#
 
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
inPoint1 const Point2D&
inPoint2 const Point2D&
inAngle float
inScale float 0.001 - 1.0f
inScaleDivisor float 0.001 - 1.0f
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.
