Working for the Correll Lab at the University of Colorado, my senior project team was responsible for developing an interactive front-end for their swarm robotics simulation library. My contribution to the project was development of the core architecture and renderer for the front-end using Qt and OpenGL Core Profile. The resulting client interacts with the simulation library asynchronously and is capable of visualizing thousands of objects while remaining interactive.
