Description
The operator distance_sldistance_slDistanceSlDistanceSldistance_sl calculates the minimum and maximum
orthogonal distance between a line segment and a line.
As input the coordinates of two points on the line segment
(RowA1RowA1RowA1rowA1row_a1,ColumnA1ColumnA1ColumnA1columnA1column_a1,RowA2RowA2RowA2rowA2row_a2,ColumnA2ColumnA2ColumnA2columnA2column_a2)
and on the line
(RowB1RowB1RowB1rowB1row_b1,ColumnB1ColumnB1ColumnB1columnB1column_b1,RowB2RowB2RowB2rowB2row_b2,ColumnB2ColumnB2ColumnB2columnB2column_b2)
are expected. 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'"N""N""N""N".
Parameters with tuple length 1 will be repeated internally
such that the number of computed distances is always 'N'"N""N""N""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.
