Description

points_to_pluecker_linepoints_to_pluecker_linePointsToPlueckerLinePointsToPlueckerLinepoints_to_pluecker_line converts the 3D line given by the two points (Point1XPoint1XPoint1Xpoint1Xpoint_1x, Point1YPoint1YPoint1Ypoint1Ypoint_1y, Point1ZPoint1ZPoint1Zpoint1Zpoint_1z) and (Point2XPoint2XPoint2Xpoint2Xpoint_2x, Point2YPoint2YPoint2Ypoint2Ypoint_2y, Point2ZPoint2ZPoint2Zpoint2Zpoint_2z) to Plücker coordinates (LineDirectionXLineDirectionXLineDirectionXlineDirectionXline_direction_x, LineDirectionYLineDirectionYLineDirectionYlineDirectionYline_direction_y, LineDirectionZLineDirectionZLineDirectionZlineDirectionZline_direction_z) and (LineMomentXLineMomentXLineMomentXlineMomentXline_moment_x, LineMomentYLineMomentYLineMomentYlineMomentYline_moment_y, LineMomentZLineMomentZLineMomentZlineMomentZline_moment_z). For the definition of Plücker coordinates, see “Solution Guide III-C - 3D Vision”. All input tuples must be of same length.

Let denote the first point (Point1XPoint1XPoint1Xpoint1Xpoint_1x, Point1YPoint1YPoint1Ypoint1Ypoint_1y, Point1ZPoint1ZPoint1Zpoint1Zpoint_1z) and the second point (Point2XPoint2XPoint2Xpoint2Xpoint_2x, Point2YPoint2YPoint2Ypoint2Ypoint_2y, Point2ZPoint2ZPoint2Zpoint2Zpoint_2z) on the line. To compute the line direction , the vector and its length are computed. If , the points do not define a line and an error is returned. The line direction is given by . The line moment is given by the cross product .

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.
