UltraGrid: Real-time Image Compression

Summer 2007

Technologies: C, OpenGL, pthreads
This project's goal was to implement real-time image compression for UltraGrid, a high definition (1080i) video conferencing application. I utilized Luc Renambont's FastDXT library, in conjunction with OpenGL fragment shaders to achieve this. The DXT compression reduced bandwidth requirements from 1.5 Gb/s to 250 Mb/s. A paper describing the work in detail will be available shortly.


IsoView: Real-time Remote Vizualization

Fall 2005 - Spring 2006

IsoView Screenshot Technologies: C++, OpenGL
This project involved re-writing sections of the existing IsoView client, which depended on VTK to a pure OpenGL implementation. The client allows for users to remotely connect to running Cactus simulations and visuzalize their data in real-time.
