Polygon_Intersection 1.0

This function computes n-times intersection region of shapes collection and allows to identify every intersection region in which shapes intersect.The function takes one argument as input, a structure S containing geometrical descriptions of shapes, and delivers one output argument, a structure containing the different shape intersections, with the shape indexes involded in the intersection and the associated area. The second argument is optional. Display_result is a binary value which indicates whether the result should be displayed (1) or not (0).Input: S : Structure containing geometrical description of polygons. S(i) contains all information relative to the i-th shape S(i).P(j) gives access to the geometrical description of the j-th element of the i-th shape. XData : S(i).P(j).x : Vector YData : S(i).P(j).y : Vector Hole : S(i).P(j).hole : Binary value (1= hole, 0= fill). This binary variable indicates whether the consider polygon S(i).P(j) is a hole or not. Hole are represented with dotted lines on figures.Output: Geo : Structure containing geometrical description of the intersection polygons, their area, and shape indexes used to compute the intersection. Geo(i).index contains the polygon indexes Geo(i).P contains the geometry of the polygon P is a structure containing XData & YData of polygons. XData : Geo(i).P(j).x : Vector YData : Geo(i).P(j).y : Vector Hole : Geo(i).P(j).hole : Binary value (1 = hole, 0= fill) Geo(i).area contains the area of the i-th shape
