Detailed Description

Ellipse Ellipse.hxx cadex/Geom/Ellipse.hxx.

Defines 3D ellipse.

An ellipse is defined by axis placement, major and minor radii. The following image depicts an ellipse example:

Ellipse

An ellipse is a periodic curve parametrized as follows: \(\mathbf{C}(t) = \mathbf{P} + R_{major}\cos(t)\mathbf{X} + R_{minor}\sin(t)\mathbf{Y}\), where

• \(\mathbf{P}\) is an origin point,
• \(\mathbf{X}\) and \(\mathbf{Y}\) are directions,
• \(R_{major}\) and \(R_{minor}\) are major and minor radii,
• \(t\) belongs to \([0, 2\pi]\).

Note that major radius is always along the X-axis and minor radius - along the Y-axis, and that the \(\mathbf{C}(0)\) point lies on the major radius.
