Detailed Description
To store and treat an ellipsoidal figure.
Constructor & Destructor Documentation
| Ellipse | ( | ) |
Default constructor.
Constructs an ellipse with semimajor axis = 1, and semiminor axis = 1
Constructor with given ellipse data.
- Parameters
-
[in] c Coordinates of center [in] a Semimajor axis [in] b Semiminor axis [in] code Code to assign to the generated figure [Default: 1]
Member Function Documentation
Return signed distance of a given point from the current ellipse.
The computed distance is negative if p lies in the ellipse, positive if it is outside, and 0 on its boundary
- Parameters
-
[in] p Point<double> instance
Reimplemented from Figure.
Operator +=
Translate ellipse by a vector a
- Parameters
-
[in] a Vector defining the translation
