My favorite commercial of all times is the Sony Bravia ad, with the bouncing balls. Crytek (the devs behind Crysis) showed of their own version at GDC. They render the whole thing realtime in their engine, and it’s quite impressive. Here are both versions for comparison.
Sony Bravia. Color like no other.
Crytek Cryengine 2. Realtime like no other
The Cryengine 2 demo shows hundreds of bouncing teapots with realtime physics and shadows. Now that we’re getting close to photorealism and realistic physics – dare we dream that AI will be the next big thing?
