get_points_ellipseget_points_ellipseGetPointsEllipseget_points_ellipseGetPointsEllipseGetPointsEllipse returns the point
(RowPointRowPointRowPointRowPointRowPointrowPoint,ColPointColPointColPointColPointColPointcolPoint) on the specified ellipse
corresponding to the angle in AngleAngleAngleAngleAngleangle.
With the parameter AngleAngleAngleAngleAngleangle you are setting the eccentric anomaly,
which denotes the angle used for the parametric equation (see the
figure below) and refers to the main axis of the ellipse.
The ellipse itself is characterized by
the center (RowRowRowRowRowrow, ColumnColumnColumnColumnColumncolumn), the orientation of the
main axis PhiPhiPhiPhiPhiphi relative to the horizontal axis, the length of
the larger (Radius1Radius1Radius1Radius1Radius1radius1) and the smaller half
axis (Radius2Radius2Radius2Radius2Radius2radius2). The angles are measured counter clockwise in
radiants.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
Angle corresponding to the resulting point [rad].
Default value: 0
Restriction: Angle >= 0 && Angle <= 6.283185307
Row coordinate of the center of the ellipse.
Column coordinate of the center of the ellipse.
Orientation of the main axis [rad].
Restriction: Phi >= 0 && Phi <= 6.283185307
Length of the larger half axis.
Restriction: Radius1 > 0
Length of the smaller half axis.
Restriction: Radius2 >= 0
Row coordinate of the point on the ellipse.
Column coordinates of the point on the ellipse.
