Detailed Description

Data structure for the representation of a 2D ellipse.

The function PrimitivesDrawer::DrawEllipse draws an ellipse, given its specification in this struct. Other functions (e.g. detectors) can use this struct as well.

Member Data Documentation

float Ellipse2d::angle

The rotiation angle of the ellipse, given in radians.

Note that a positive angle will rotate the ellipse clockwise, as the y-axis of the image coordinate system is oriented downward. In the IVt, the rotation angles are consistent for all algorithms/functions that involve rotations.

Vec2d Ellipse2d::center

The center of the ellipse.

Definition at line 142 of file Structs.h.

float Ellipse2d::radius_x

The radius in horizontal direction of the ellipse (horizontal refers to when angle = 0).

Definition at line 147 of file Structs.h.

float Ellipse2d::radius_y

The radius in vertical direction of the ellipse (vertical refers to when angle = 0).
