A few years ago I became interested in first person shooter games and in particular how the world levels are created and rendered in real time. At the same time I found myself in between jobs and so I embarked on an effort to learn about 3D rendering with the goal of creating my own 3D rendering engine. Since I am a developer and not an artist I didn’t have the skills to create my own models, levels, and textures. So I decided to attempt to write a rendering engine that would render existing game levels. I mainly used information and articles I found on the web about Quake 2, Half Life, WAD and BSP files. In particular I found the Michael Abrash articles that he wrote for Dr. Dobbs magazine while working at Id to be very illuminating.

The new digital radio system DAB (Digital Audio Broadcasting, nowadays often called Digital Radio) is a very innovative and universal multimedia broadcast system which will replace the existing AM and FM audio broadcast services in many parts of the world in the future. It was developed in the 1990s by the Eureka 147/DAB project. DAB is very well suited for mobile reception and provides very high robustness against multipath reception. It allows use of single frequency networks (SFNs) for high frequency efficiency.
