Description

intersection_circlesintersection_circlesIntersectionCirclesIntersectionCirclesintersection_circles calculates the intersection points of two circles or circular arcs. The points, if any, are returned in (RowRowRowrowrow,ColumnColumnColumncolumncolumn). The circles are defined by their center (Circle1RowCircle1RowCircle1Rowcircle1Rowcircle_1row,Circle1ColumnCircle1ColumnCircle1Columncircle1Columncircle_1column), and (Circle2RowCircle2RowCircle2Rowcircle2Rowcircle_2row,Circle2ColumnCircle2ColumnCircle2Columncircle2Columncircle_2column) respectively, and their radii Circle1RadiusCircle1RadiusCircle1Radiuscircle1Radiuscircle_1radius, and Circle2RadiusCircle2RadiusCircle2Radiuscircle2Radiuscircle_2radius respectively. In addition to that, a circular arc is characterized by the angle of the start point (Circle1StartPhiCircle1StartPhiCircle1StartPhicircle1StartPhicircle_1start_phi,Circle2StartPhiCircle2StartPhiCircle2StartPhicircle2StartPhicircle_2start_phi), the angle of the end point (Circle1EndPhiCircle1EndPhiCircle1EndPhicircle1EndPhicircle_1end_phi,Circle2EndPhiCircle2EndPhiCircle2EndPhicircle2EndPhicircle_2end_phi), and the point order (Circle1PointOrderCircle1PointOrderCircle1PointOrdercircle1PointOrdercircle_1point_order,Circle2PointOrderCircle2PointOrderCircle2PointOrdercircle2PointOrdercircle_2point_order) along the boundary. If Circle1PointOrderCircle1PointOrderCircle1PointOrdercircle1PointOrdercircle_1point_order is set to 'positive'"positive""positive""positive""positive", the circular arc is defined counterclockwise. If Circle1PointOrderCircle1PointOrderCircle1PointOrdercircle1PointOrdercircle_1point_order is set to 'negative'"negative""negative""negative""negative", the circular arc is defined clockwise. The same applies for Circle2PointOrderCircle2PointOrderCircle2PointOrdercircle2PointOrdercircle_2point_order. If both circles or circular arcs have a part in common IsOverlappingIsOverlappingIsOverlappingisOverlappingis_overlapping returns the value 1, otherwise 0 is returned. In this case the endpoints of the mutual arc are returned in (RowRowRowrowrow,ColumnColumnColumncolumncolumn).

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.
