Detailed Description

This class implements construction algorithms for gp_Elips2d. Supported constructions include:

• ellipse from major axis (or local 2D coordinate system) and radii;
• ellipse from center and two points.

Constructor & Destructor Documentation

gce_MakeElips2d() [1/3]

gce_MakeElips2d::gce_MakeElips2d	(	const gp_Ax2d &	MajorAxis,
		const double	MajorRadius,
		const double	MinorRadius,
		const bool	Sense = true )

Creates an ellipse with the major axis, the major and the minor radius. The location of the MajorAxis is the center of the ellipse. The sense of parametrization is given by Sense. It is possible to create an ellipse with MajorRadius = MinorRadius.

Note

Construction fails with gce_InvertRadius if MajorRadius < MinorRadius.

Construction fails with gce_NegativeRadius if MajorRadius < 0.0.

Parameters

[in]	MajorAxis	major axis placement
[in]	MajorRadius	major radius value
[in]	MinorRadius	minor radius value
[in]	Sense	orientation flag

gce_MakeElips2d() [2/3]

gce_MakeElips2d::gce_MakeElips2d	(	const gp_Ax22d &	A,
		const double	MajorRadius,
		const double	MinorRadius )

Axis defines the Xaxis and Yaxis of the ellipse which defines the origin and the sense of parametrization. Creates an ellipse with the AxisPlacement the major and the minor radius. The location of Axis is the center of the ellipse. It is possible to create an ellipse with MajorRadius = MinorRadius.

Note

Construction fails with gce_InvertRadius if MajorRadius < MinorRadius.

Construction fails with gce_NegativeRadius if MajorRadius < 0.0.

Parameters

[in]	A	local coordinate system
[in]	MajorRadius	major radius value
[in]	MinorRadius	minor radius value

gce_MakeElips2d() [3/3]

gce_MakeElips2d::gce_MakeElips2d	(	const gp_Pnt2d &	S1,
		const gp_Pnt2d &	S2,
		const gp_Pnt2d &	Center )

Creates an ellipse from center and two points.

Note

S1 defines major radius direction and value.

Minor radius is computed as distance from S2 to major axis.

Construction fails with gce_NullAxis when computed minor radius is null.

Construction fails with gce_InvertAxis when computed minor radius exceeds major radius.

Parameters

[in]	S1	first point
[in]	S2	second point
[in]	Center	center point
