Detailed Description

This class represents 3D elliptical arcs and full ellipses in 3D space.

Remarks: The angle of a point on an ellipse is measured by projecting the point along a vector perpendicular to the major axis onto a circle whose center is the center of this ellipse and whose radius is the major radius of this ellipse. The angle between the major axis of the ellipse and a vector from the center of the ellipse to the intersection point with the circle, measured counterclockwise about the crossproduct of the major and minor axes, is the angle of the point on the ellipse.

Remarks: All angles are expressed in radians.; The result of this method should not be used as a curve parameter. The angles and its corresponding parameter may differ.

◆ startPoint()

OdGePoint3d OdGeEllipArc3d::startPoint ( ) const

Returns the start point of this elliptical arc.

Returns: An instance of the OdGePoint3d class.

◆ tangentAt()

OdGeVector3d OdGeEllipArc3d::tangentAt ( double param ) const

Returns the tangent vector at the point specified by param.

Parameters

param [in] Parameter corresponding to the point at which to compute the tangent.
