Description
intersection_line_circleintersection_line_circleIntersectionLineCircleIntersectionLineCircleintersection_line_circle calculates the intersection points of
a line and a circle or circular arc. The line is defined by the points
(LineRow1LineRow1LineRow1lineRow1line_row_1,LineColumn1LineColumn1LineColumn1lineColumn1line_column_1) and
(LineRow2LineRow2LineRow2lineRow2line_row_2,LineColumn2LineColumn2LineColumn2lineColumn2line_column_2). The circle is defined
by its center (CircleRowCircleRowCircleRowcircleRowcircle_row,CircleColumnCircleColumnCircleColumncircleColumncircle_column) and its radius
CircleRadiusCircleRadiusCircleRadiuscircleRadiuscircle_radius. In addition to that, a circular arc is characterized
by the angle of the start point CircleStartPhiCircleStartPhiCircleStartPhicircleStartPhicircle_start_phi, the angle of the
end point CircleEndPhiCircleEndPhiCircleEndPhicircleEndPhicircle_end_phi, and the point order
CirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrdercircle_point_order along the boundary.
If CirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrdercircle_point_order is set to 'positive'"positive""positive""positive""positive", the circular arc
is defined counterclockwise.
If CirclePointOrderCirclePointOrderCirclePointOrdercirclePointOrdercircle_point_order 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.
