A structure used for describing and manipulating 2D circular arcs
Does this come out?

Public Fields

Center	Point2F The center of the arc.
Direction	CamBam.Geom.RotationDirection Direction of rotation
P1	Point2F First arc point.
P2	Point2F Second arc point.

Properties

Bulge readonly	System.Double Bulge is used in DXF polylines. It is defined as Tan of 1/4 the sweep angle Returns:
Midpoint readonly	Point2F
Radius readonly	System.Double The radius of the arc. NOTE: Calculated from distance from Center to P1 and P2
Start readonly	System.Double The start angle in degrees NOTE: Calculated from Center and P1
Sweep readonly	System.Double The sweep angle in degrees NOTE: Calculated from Center, P1 and P2
Undefined static,readonly	Arc2F

Methods

_CalcPolyArcSweep static	Double _CalcPolyArcSweep (Point2F p1, Point2F p2, Point2F pmid)
AngleWithinArc	Boolean AngleWithinArc (Double angle, Double tolerance) Checks that an angle lies within the arc Parameters: angle: angle to test in degrees Returns: true if the angle lies within the arc
ArcIntersect	Line2F ArcIntersect (Arc2F arc, Double tolerance) Finds the intersection points between two arcs. Parameters: arc: Arc to test Returns: A 2D Line where the end points are the points of intersection. If the arcs do not intersect Line2F.Undefined is returned.
ArcIntersect	Line2F ArcIntersect (Arc2F arc)
CircleIntersect	Line2F CircleIntersect (Circle2F circle, Double tolerance) Finds the intersection points between the arc and a circle. Parameters: circle: The circle to test. Returns: A 2D Line where the end points are the points of intersection. If the circle does not intersect Line2F.Undefined is returned.
CircleIntersect	Line2F CircleIntersect (Circle2F circle)
DistanceToPoint	Double DistanceToPoint (Point2F p) Calculates the shortest distance from a point to the arc Parameters: p: The point to test Returns: The scalar distance to the arc
GetArcFromMidpoint static	Arc2F GetArcFromMidpoint (Point2F p1, Point2F p2, Point2F pmid)
GetBulgeDirectionLeftRight	ArcBulgeDirection GetBulgeDirectionLeftRight ()
GetBulgeDirectionUpDown	ArcBulgeDirection GetBulgeDirectionUpDown ()
GetExtrema	Void GetExtrema (Point2F& min, Point2F& max)
GetPerimeter	Double GetPerimeter ()
Invert	Void Invert ()
IsInside	Boolean IsInside (Rect2F rect)
LineIntersect	Line2F LineIntersect (Line2F line, Double tolerance) Finds the intersection points between the arc and a line. Parameters: line: The line to test Returns: A 2D Line where the end points are the points of intersection. If the line does not intersect the arc, returns Line2F.Undefined.
NearestPoint	Point2F NearestPoint (Point2F p, Double& distance)
NearestPoint	Point2F NearestPoint (Line2F line, Double& distance, Double tolerance)
NearestPoint	Point2F NearestPoint (Arc2F arc, Double& distance, Double tolerance)
P1Tangent	Vector2F P1Tangent ()
P2Tangent	Vector2F P2Tangent ()
RadiusOffset	Boolean RadiusOffset (Double delta)
RayIntersect	Line2F RayIntersect (Line2F line, Double tolerance) Finds the intersection points between the arc and a ray Parameters: line: The ray to test Returns: A 2D Line where the end points are the points of intersection. If the line does not intersect the arc, returns Line2F.Undefined.
RegionInside	Boolean RegionInside (Rect2F rect)
RenderToPoints	Point3FArray RenderToPoints (Double tolerance)
SplitAtPoint	Arc2F[] SplitAtPoint (Point2F p)
SweepDiff	Double SweepDiff (Point2F p) Used in offset polyline calculations Parameters: p: Returns:
VectorInsideArc	Boolean VectorInsideArc (Vector2F v)
