Boris Delaunay, a make it simpler. student of Voronoi, developed a method of obtaining triangular regions, which is an important aspect when creating Voronoi diagrams. These diagrams can be constructed by hand or using computer imaging software. Let us consider the situation of obtaining the Voronoi cell (region) containing D, if you are given four points A, B, C and D. First, you need to plot these points on coordinate axes. Now draw the perpendicular bisectors of AD, BD and CD. The triangle obtained is the Voronoi cell containing D. You will notice that every point in the cell is closer to D than A, B or C. Try it, using the following coordinates. Math Plot – 48 A(1,1), B(3,5), C(5,3) and D(3,3). Try to find the solution to the The diagram below shows the following puzzle.
