PSU made an interview with Christophe Balestra, Co-President of Naughty Dog. They talk about the necessity of Blu-ray and the power of the Cell processor, the technology behind the game and more.
PSU: How does the animation system and graphics in Drake's Fortune benefit from the Cell and SPU's?
Christophe Balestra: One of our first goals when we started Uncharted: Drake's Fortune was to push what's been done in animation for video games. We developed a brand new animation system that took full advantage of the SPU's. Nathan Drake's final animation is made of different layers like running, breathing, reloading weapons, shooting, facial expression, etc; we end up decompressing and blending up to 30 animations every frame on the SPU's.
And this is just for Nathan Drake; we have a lot more than that when you add the NPC's and enemies.
