RTGames - Computer Games Based on Ray Tracing


Recently, realtime ray tracing has been developed to the point where it is becoming a possible alternative to the current rasterization approach for interactive 3D graphics. With the availability of a first prototype graphics board purely based on ray tracing, we have all the ingredients for a new generation of 3D graphics technology that could have significant consequences for computer gaming. However, hardly any research has been looking at how games could benefit from ray tracing based graphics.

The RTGames working group tries to fill this gap with the development of computer games based on ray tracing. With these academic studies, we evaluate the process of adapting existing rasterization based games (partly using original game content) to ray tracing. Additionally we evaluate new ways how computer games could look like if they where directly developed to use ray tracing.

The games where developed using OpenRT, an API similar to OpenGL, which transparently hides the actual implementation of the ray tracer. Like the MESA-System for OpenGL, OpenRT includes a highly optimized software ray tracer, which runs on a single CPU as well as on a cluster of PC (with linear speed-up per CPU). Alternatively to the software ray tracer, with SaarCOR a first prototype of a graphics board purely based on ray tracing is available.

Game Projects:
 
Project Oasen Q3RT Ray City
Genre Flying Ego-Shooter Racing
Status Playable Playable Tech-Demo


We are very much interested in evaluating new ways for computer games and therefore like to cooperate with the gaming industry. Thus if you are in such a position, please send us an email!
