PhyreEngine (also known as Phyre Engine) is a free to use, cross platform (Windows, PSP, PS Vita and PS3) game engine from Sony Computer Entertainment. By 2011 PhyreEngine had been adopted by dozens of game studios to power almost fifty games for the PlayStation Store or on Blu-ray Discs.
PhyreEngine is distributed as an installable package that includes both full source code and PC Windows tools, provided under its own flexible use license that allows any PS3 game developer, publisher or Tools & Middleware company to create software based partly or fully on PhyreEngine on any platform.
The engine uses sophisticated parallel processing techniques that are optimized for the Synergistic Processor Unit (SPU) of the Cell Broadband Engine of PS3, but can be easily ported to other multi-core architectures.
PhyreEngine supports OpenGL and Direct3D, in addition to the low level PS3 LibGCM library. It also provides fully functional "game templates" as source code, including support for Havok Complete XS, NVIDIA PhysX and Bullet for physics.
