Recently my friend Josh Hammer has been sending a TON of tweets.  He is a staunch Republican and Mitt Romney supporter.  If you want to read every news story through the GOP lens, subscribe to his Twitter feed.  He is effectively a GOP Twitter bot. In the past couple of weeks, his tweeting began to […]

Interactive Quadtrees and Well-Separated Pairs Decomposition

January 16th, 2012 · 4 Comments

While doing computational geometry research with Professor Pankaj K. Agarwal and Thomas Mølhave at Duke, we looked at using quadtrees and the well-separated pairs decomposition (WSPD) for one of our algorithms. As I was reading about the algorithms and geometric concepts, I decided to code them in Javascript and HTML5’s canvas to get more intuition […]

Announcing TerraNNI

November 9th, 2011 · No Comments

I am excited to announce that TerraNNI, the project from my undergraduate senior thesis, is being open-sourced. For those who have not heard of the project, TerraNNI is a tool for taking LIDAR data, common for geographic information systems (GIS), and creating high-resolution grid digital elevation models (DEMs).  Most GIS take DEMs as an input […]

Interactive Voronoi Diagrams with WebGL

August 2nd, 2010 · 19 Comments

Within computational geometry, the Voronoi diagram is a relatively simple concept with a wide-range of applications.  Everything from physics research to the “snap-to” feature in GUI-design uses Voronoi diagrams as a simple underlying data structure to decompose space. I have been working with Voronoi diagrams for the past few months, as my research has focused […]

CMake, OpenGL, and GLX on OS X

July 28th, 2010 · 4 Comments

As you may know, I am staying at Duke this summer for research.  My research, which I started last semester and am going to be doing for a while, focuses on scalable algorithms.  While that is pretty broad, I am currently working on using the graphics card to speed up processing. Again, here are some […]
