I captured some early scenes from Doom 3 and applied the recently released "Rotoscope Cartoon Shader 1.0" mod and compared it with the original footage from the game. Also used a Virtual Dub filter called "MSU Cartoonizer" for another version of the cartoon effect. Links for download are shown at the end of the video. As of 8/20/06 there is a newer version of the Rotoscope mod (1.1) which has been released for Quake 4 and Prey, but not quite yet for Doom 3.
