Nvidia has announced today that it will be giving away the binary version of its PhysX software development kit to registered PlayStation 3 developers for free. The move comes as part of a tools and license middleware agreement that the graphics chip company signed with Sony and will enable game makers to implement hardware-accelerated physics in their projects.

The SDK consists of a full-featured API that enables developers to increase the visual experience of their games by offering creative control over physical interactions and real-time effects previews. The technology, which was most recently adopted in the first person action-adventure title Mirror's Edge, is also compatible with Microsoft's Xbox 360 console and of course PCs fitted with a relatively new GeForce card.
