ProjectPointOnCircle

Header:	FIL.h
Namespace:	fil

Projects a point onto a circle.

Syntax

void fil::ProjectPointOnCircle
(
	const fil::Point2D& inPoint,
	const fil::Circle2D& inCircle,
	fil::Point2D& outProjectionPoint
)

Parameters

	Name	Type	Default	Description
	inPoint	const Point2D&
	inCircle	const Circle2D&
	outProjectionPoint	Point2D&

Description

Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when the input point and the center of the input circle are almost equal.

Examples

ProjectPointOnCircle performed on point and circle.
