3) We begin with first point of entering list I1. We take next point on list for P until we get exiting point I0. We go to list for Q and take next point I2. As I2 is exiting ...
Weiler - Atherton algorithm We use this algorithm to find union or intersection of not crossed polygons We have two polygons P and Q, vertices are given in order
1 ) We calculate intersections of sides and put them in two lists : P0 ; I1 ; I0 ; P1 ; I2 ; I3 ; P2 ; I4 ; P3 ; I5 ; P4 for polygon P Q0 ; Q1 ; I0 ; I2 ; Q2 ; Q3 ; I5 ; I4 ; I3 ; I1 for polygon Q 2 ) We have also list of entering points for P : I1 ; I2 ; I4 3) We begin with first point of entering list I1 We take next point on list for P until we get exiting point I0 We go to list for Q and take next point I2 As I2 is exiting for Q, we go to list for P As I3 is exiting for P, we go to list for Q We retrieve point for begining I1 First common area is polygon I1 I0 I2 I3 4) We delete entering points in this area I1 and I2 from entering list 5) We take last point in entering list I4 We find on P list P3 then I5 As I5 is exiting we go to Q list and find I4 Second common area is I4 P3 I5 As entering list of points is empty, we have all common areas If polygons are crossed, this algorithm give false results because we cannot decide if a point is entering or existing for the polygon. We can use this algorithm to find union of areas, we have only to exchange entering and exiting properties. You can test this algorithm with embedded svg above
Painter's Algorithm. ⢠Sort polygons by farthest depth. ⢠Check if polygon is in front of any other. ⢠If no, render it. ⢠If yes, has its order already changed backward?Missing:
