This dialog allows you to thin points by region. Regions can be:
-Rectangles
-Polygons
-Corridors
For each region, point thinning is controlled by a # Skipped. The # Skipped is the number of points skipped after a point is read.
Examples:
# skipped = 0 ==> all points are included (100%)
# skipped = 1 ==> one is read and one is skipped (50%)
# skipped = 2 ==> one is read and two are skipped (33%)
It is possible to create several regions with different spacing in each. Points are thinned according to the first region which contains them. Regions can be inside or outside. A Default region always exists.
