With this program you can select a point light-source with the mouse (just left-click where you want when the mouse cross-hairs appear), and you will see the curve created by the envelope of reflected light rays from the surface of the chosen curve. It achieved by accurately estimating the derivative of the curve at each point the light hits it, from which I calculate the Unit Normal vector to the curve at that point, from which I can work out the correct reflected ray.Using Catacaustic Curves application you will be able to draw different types of catacaustic curves, depending and according to the input parameters. This version is the first release on CNET Download.com.
