Description
intersection_segment_circleintersection_segment_circleIntersectionSegmentCircleIntersectionSegmentCircleIntersectionSegmentCircleintersection_segment_circle calculates the intersection point of
a segment and a circle or circular arc. The segment is defined by its
endpoints (SegmentRow1SegmentRow1SegmentRow1SegmentRow1segmentRow1segment_row_1,SegmentColumn1SegmentColumn1SegmentColumn1SegmentColumn1segmentColumn1segment_column_1) and
(SegmentRow2SegmentRow2SegmentRow2SegmentRow2segmentRow2segment_row_2,SegmentColumn2SegmentColumn2SegmentColumn2SegmentColumn2segmentColumn2segment_column_2). 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.
