Thanks to a new tools and middleware license agreement between NVIDIA and Sony, game developers may find the PlayStation 3 to be a more attractive platform. As a result of the agreement, registered PS3 developers will now have access to the NVIDIA PhysX technology software development kit (SDK). The SDK will be a free download for use on the SCEI Developer Network. The NVIDIA PhysX SDK gives developers, animators, level designers, and artists creative control over character and object physical interactions.
