[The Glowball Demo] also leverages the accelerometer inside the device, affecting real-time movements of drapes throughout the game. As the user tilts the device, the gravity in the scene changes and drapes respond accordingly. The movements are calculated using physics and are simulated across Project Kal-El’s four CPU cores. Again, no canned animations. As the ball rolls through the drapes, they respond how you’d expect them to in real life. In addition, as the ball collides into the jack-in-the-boxes and barrels, the scene responds. Notice how the visual quality degrades when only two CPU cores are used. It’s clear that the quad-core processor in Project Kal-El is required for this level of realism.
