Radiosité temps réel...
"Most likely the single most important aspect of cinematography is lighting. Lighting contributes considerably to the emotional response an audience has watching a motion picture." (Wikipedia)
No-one would claim the visual quality of video games has yet reached that of film, but the challenges faced by the cinematographer and the game artist are the same: to achieve consistent, realistic lighting that creates the desired mood.
The cinematographer is typically forced to experiment with extra lights and occluders off-camera in order to achieve presentable results. With current technology, the game artist is obliged to do the same, in what can be a frustrating and time-consuming process that ultimately only decreases the possibilities for interactivity.
With Enlighten, realism comes for free. Light from all sources in the scene is accurately computed in real-time; and not just the first bounce, but the whole global solution. With a fully immersive environment guaranteed, the artist is free to concentrate on quality.
And since the lighting calculations are fully configurable, he can even change the laws of physics... what the cinematographer wouldn't give for the possibilities offered by Enlighten!
Why is Real-Time Radiosity Important?
Current game lighting technology requires large numbers of lights. Artists use additional lights to fill in areas that, in reality, are lit by light reflected off other surfaces in the scene. With dynamically computed radiosity one can achieve far greater realism with only a handful of light sources. Enlighten brings physically correct dynamic lighting to this generation of game development.
Enlighten computes all bounced lighting and global illumination in real time – the first time this has ever been possible. By removing the need for artists to painstakingly mimic realistic lighting, time to create artwork is dramatically reduced. And with frame rates over 100fps Enlighten can be incorporated into any game setting.
