Reduce Contour

Node Icon

Reduces the number of points of contours by calculating the area of the parallelogram defined by 3 consecutive points on the contour. One side is defined by point 1-2 and the other by 1-3. If the area of the parallelogram is less the the stopping criteria, point 2 is discarded. The process is iterative and will be continued until maximum iterations is reached, or no more points can be discarded with set stopping criteria.
