Constructor & Destructor Documentation

Circle()

Circle	(	Point2Dd	center,
		double	radius
	)

Create a circle.

Parameters

center	center of the circle
radius	radius of the circle

Member Function Documentation

Contains()

bool Contains

(

Point2Dd

pt

)

Check whether a point is inside or outside a circle.

Parameters

pt	point to be checked

Returns

bool if pt lies inside the circle, false otherwise

IsOnRadius()

bool IsOnRadius	(	Point2Dd	pt,
		double	epsilon
	)

Check whether a point is on the radius of a circle (or at least within a small epsilon thereof).

Parameters

pt	point to be checked
epsilon	maximum allowable deviation

Returns

true if pt lies within epsilon length units of this circle's radius
