APPLET
The purpose of the applet is to demonstrate
edge flipping in triangulations and visualize what happens when you flip an
edge.
To begin:
 Click on the canvas to create
vertices. You can create as many vertices as you like. Each
time a new vertex the original triangulation is altered to add the new
vertex but the delaunay triangulation is created each time.
 At any time you can select the "voronoi"
diagram to see the voronoi diagram of the vertices and ensure that the
initial triangulation is the delaunay triangulation.
 Delete any vertex by pressing the alt key
and clicking on the vertex to be deleted.
To Flip Edges:
 Select the "Flip Edges"
button.
 Select the edge to flipped. This can
be done by clicking on the vertices of the edge.
 When finished edge flipping select the
"flip edges" button again.
Continuing:
 The "Clear" button clears the
graph and thus, you can begin creating a new graph.
 Select the "Flip Edges" button to
start edgeflipping at any point. When finished edge flipping
select the "Flip Edges" to bring you back to the "Create
Graph" mode.
