Description

test_self_intersection_xldTestSelfIntersectionXld tests whether the input contours or polygons in XLDXLDxld intersect or touch themselves. The output array DoesIntersectdoesIntersectdoes_intersect contains a 11 if the corresponding input contour or polygon intersects or touches itself and 00 otherwise.

If the input parameter CloseXLDcloseXLDclose_xld is set to 'true'"true", open contours or polygons are closed before the check is performed by simply connecting the first and the last contour or polygon point with a line segment.

Attention

A contour or polygon touches itself if a contour or polygon point lies exactly on a contour or polygon segment. However, whether a point lies exactly on a contour or polygon segment or not can practically not be decided because of numerical reasons.

Execution information

Execution information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).

• Multithreading scope: global (may be called from any thread).

• Automatically parallelized on tuple level.

Parameters
