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).
