Description
intersection_segment_circleintersection_segment_circleIntersectionSegmentCircleIntersectionSegmentCircleIntersectionSegmentCircle
calculates the intersection point of
a segment and a circle or circular arc. The segment is defined by its
endpoints (SegmentRow1SegmentRow1SegmentRow1SegmentRow1segmentRow1
,SegmentColumn1SegmentColumn1SegmentColumn1SegmentColumn1segmentColumn1
) and
(SegmentRow2SegmentRow2SegmentRow2SegmentRow2segmentRow2
,SegmentColumn2SegmentColumn2SegmentColumn2SegmentColumn2segmentColumn2
). The circle is defined
by its center (CircleRowCircleRowCircleRowCircleRowcircleRow
,CircleColumnCircleColumnCircleColumnCircleColumncircleColumn
) and its radius
CircleRadiusCircleRadiusCircleRadiusCircleRadiuscircleRadius
. In addition to that, a circular arc is characterized
by the angle of the start point CircleStartPhiCircleStartPhiCircleStartPhiCircleStartPhicircleStartPhi
, the angle of the
end point CircleEndPhiCircleEndPhiCircleEndPhiCircleEndPhicircleEndPhi
, and the point order
CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrder
along the boundary.
If CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrder
is set to 'positive'"positive""positive""positive""positive", the circular arc
is defined counterclockwise.
If CirclePointOrderCirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrder
is set to 'negative'"negative""negative""negative""negative", the circular arc
is defined clockwise.
The intersection points, if any, 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.
