Nvidia has a video that features a demo they created called “Glowball,” which draws its namesake from the feature character: a brilliant lit, bouncing ball. The ball serves as the light source. As it rolls, it casts its effect on different objects. This shows off the power of true dynamic lighting, rendered in real-time with physics (no canned animations here, folks). Thanks to Project Kal-El, Glowball’s true dynamic lighting brings more life and interactivity to a 3D environment. This marks the first time this type of lighting is feasible on a mobile device. Glowball 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.
