Physics engine
abstract:A physics engine is computer software that provides an approximate simulation of certain physical systems, such as rigid body dynamics (including collision detection), soft body dynamics, and fluid dynamics, of use in the [of computer graphics], [[video games and film. Their main uses are in video games (typically as middleware), in which case the simulations are in real-time.
It promises not just new birds and cute little masks for the existing ones, but a revamped physicsengine with shifting gravity focused around asteroids and planets rather than one consistent force.
What you see in the diagram above is that the framework maintains the in and out points of the WebKit flow, but takes a detour in the middle using its own physicsengine, render engine and rules framework to replace the native WebCore functions.
The graphics haven't been completely updated (the cars are basically still just standard polygons), but the UI is cleaner, a physicsengine has been added in with power-ups and other goodies, and there is a really robust replay system, which lets players save their best shots and stunts on video, and edit and upload those to YouTube and other video sharing services.
