Due for imminent release to PS3 developers, PlayStation 3 Edge has been put together by three first-party technology teams within Sony, the WWS Europe Advanced Technology Group, WWS America ICE team (a technology group based at Naughty Dog that specialises in graphics systems and tools for the PlayStation 3), and WWS America Tools and Technology group.
Edge is described as "a set of cutting edge technologies. Rather than an overarching engine, these teams have chosen to create specialized systems that demonstrate best practices of SPU and RSX utilization" in the description of a recently announced GDC session which will formally take the wraps off the new technology.
The GDC session, hosted by Mark Cerny (Cerny Games), Jon Olick (lead programmer, Naughty Dog) and Vince Diesi (principal programmer, SCE Worldwide Studios) looks at advanced graphics tools and technologies for PS3 development an will also show delegates "a unique tool for RSX performance analysis, extensively used in the tuning of first party titles".
