I have the polygons set up so that they each have a small alpha value so that the overlaps can be seen visually. However, when alpha is very small, it is hard to tell when there is overlap between twelve polygons or thirteen polygons merely by looking at the graph since the transparency difference is so minimal. Because of this, I would like the program user to be able to specify a point in the plane, and be returned what alpha is equal to. Is this feasible? Thanks in advance, and I'll be glad to specify any additional details that are necessary. |
