Overrides PaintTo3D(IPaintTo3D)

Returns the Parameter of the given point projected into the plane of this ellipse (pp). For a circle or arc this is the radian of the angle of the point. For an ellipse this is the value (a), where e.x = center.x+majorradius*cos(a), e.y = center.y+minorradius*cos(a) yields a point (e) on the ellipse so that (pp) coincides with the line (center,e).

Returns the intersectionpoints of this ellipse with the provided plane toIntersectWith. The result is an array with 0 to 2 GeoPoints.

gets or sets the center of this circle or ellipse

Returns true if it is not a full circle or a full ellipse, i.e. the SweepParameter is not -2*pi and not 2*pi.

Returns true if both axis of the ellipse have the same length. It may be a circle or a circular arc.

Gets or sets the startparameter of this circular or elliptical arc. The startparameter determins the startpoint of this curve according to the formula: Center + cos(StartParameter)*MajorAxis + sin(StartParameter)*MinorAxis For elliptical arcs the startparameter is not identical to the angle of the startpoint.

Gets or sets the sweep amount of this arc. A full circle or ellipse must have a sweepparameter of either 2.0*Math.PI or -2.0*Math.PI, The sweep parameter of circular or elliptical arcs are in the range of -2.0*Math.PI < SweepParameter < 2.0*Math.PI. SweepParameter is often used in connection with startParameter
