Description
intersection_circle_contour_xldintersection_circle_contour_xldIntersectionCircleContourXldIntersectionCircleContourXldIntersectionCircleContourXldintersection_circle_contour_xld calculates the intersection points
of a circle or circular arc and the XLD ContourContourContourContourcontourcontour.
The circle is defined by its center
(CircleRowCircleRowCircleRowCircleRowcircleRowcircle_row,CircleColumnCircleColumnCircleColumnCircleColumncircleColumncircle_column) and its radius
CircleRadiusCircleRadiusCircleRadiusCircleRadiuscircleRadiuscircle_radius. In addition to that, a circular arc is characterized
by the angle of the start point CircleStartPhiCircleStartPhiCircleStartPhiCircleStartPhicircleStartPhicircle_start_phi, the angle of the
end point CircleEndPhiCircleEndPhiCircleEndPhiCircleEndPhicircleEndPhicircle_end_phi, and the point order
CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrdercircle_point_order along the boundary.
If CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrdercircle_point_order is set to 'positive'"positive""positive""positive""positive""positive", the circular arc
is defined counterclockwise.
If CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrdercircle_point_order is set to 'negative'"negative""negative""negative""negative""negative", the circular arc
is defined clockwise.
The intersection points, if any, are returned in
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn).
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
