Description
The operator distance_ssdistance_ssDistanceSsDistanceSsdistance_ss calculates the minimum and maximum
distance between two line segments. As input the coordinates of the
start and end point of the
first line segment (RowA1RowA1RowA1rowA1row_a1,ColumnA1ColumnA1ColumnA1columnA1column_a1,
RowA2RowA2RowA2rowA2row_a2,ColumnA2ColumnA2ColumnA2columnA2column_a2) and of the second line segment
(RowB1RowB1RowB1rowB1row_b1,ColumnB1ColumnB1ColumnB1columnB1column_b1,RowB2RowB2RowB2rowB2row_b2,ColumnB2ColumnB2ColumnB2columnB2column_b2)
are used.
The parameters DistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max return
the result of the calculation. If the line segments are intersecting,
DistanceMinDistanceMinDistanceMindistanceMindistance_min returns zero.
Parameter Broadcasting
This operator supports parameter broadcasting.
This means that each parameter can be given as a tuple of length
1 or N.
Parameters with tuple length 1 will be repeated internally
such that the number of computed distances is always N.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on internal data level.
