ICircle_DG Interface

Oriented 3D circle with center at the origin of its local frame as specified by Init*(). Axis consides with Z axis of the local frame.

A standalone circle can be created via IObjectGenerator_DG.Create<ICircle_DG>() > ICircle_DG query.

Implements also: ICurve_DG, IGeometricObject_DG, IObject_DG.

void Init(PointDg center, VectDg axis, double radius)


void Init(IFrame_DG frame, double radius)

Defines this as a circle at the origin of the x and y plane of frame.


void Init(PointDg point0, PointDg point1, PointDg point2)


void Init(PointDg endArc0, PointDg endArc1, VectDg normal, double radius)

Defines this as circle of an arc in plane with normal in direction of normal. normal is adjusted to make it perpendicular to [endArc0, endArc1] direction.


PointDg GetPoint(double angle)


VectDg GetTangent(double angle)


void Copy(ICircle_DG circle)


ICircle_DG Clone()

Returns a new copy of this.
