-Geometric separators project for CSE 4095 (Computational Geometry).
+This program is based off the paper [Geometric Separators and the Parabolic Lift](http://donsheehy.net/research/sheehy13geometric.pdf) by Don Sheehy. It implements a new algorithm to calculate a geometric separator for a set of 2D input points.

+This Processing program will allow you to input a number of 2D points and will calculate the geometric separator for the input set. It will graphically show the centerpoint and the spherical separator projected down to the 2D plane.
+
+Usage:
+------
+
+There are three buttons on the application window: **Calculate**, **Reset**, and **Randomize**.
+You can click anywhere on the canvas to add input points. Then, use the **Calculate** button, which will show the centerpoint (if it can) and the separator projected down to the 2D plane. If you don't have specific points, you can use the **Randomize** button to add 25 random points to the canvas. To remove added points, just click **Reset**.
+
+Note: The centerpoint is estimated using Radon Points - according to Radon's Theorem, we can only find a partition for sets of 5 points, so we must only have powers of 5 for our input set.
