NVIDIA UltraShadow Technology The demand for virtual reality like gaming has forced the fast pace of 3D hardware development. With the explosion of first-person games like Counter-Strike and Battlefield 1942; players are becoming accustomed to life like visuals and 3D environments. Improving on and extending this 3D metaphor is NVIDIA’s UltraShadow Technology. Just imagine being able to see the shadow of your opponent on the wall, as he creeps around the corner; or even the shadow of his gun on the ground next to you. With UltraShadow Technology, these features will become a reality. The ability to create realistic shadows of objects in a 3D environment is one of the key components to realistic virtual worlds. And environment with real shadows has the capability to take games to a whole different level. Shadow effects; particularly those that involve multiple light sources acting on the same object, are incredibly complicated to generate correctly. The light sources must be analyzed for every relative point of an object and the effects themselves must be rendered for each frame. NVIDIA’s UltraShadow Technology allows programs the ability to create shadows more quickly and efficiently; allowing them to even fine-tune shadows within specific critical regions to elicit maximum realism. By incorporating these powerful effects directly in the GPI, NVIDIA provides game developers the means to create stunning virtual worlds and at the same time free up valuable CPU time that could be better spent of game physics and AI - bringing us one step farther along down the road to real to life virtual computing. |

“The
new NVIDIA® GeForce™ FX 5900 Ultra and GeForce FX 5900 graphics
processing units (GPUs) introduce NVIDIA UltraShadow™ technology,
accelerating the computations for determining shadow interactions within
an immersive environment. By contributing to the next generation of complex
effects, UltraShadow enables high-quality, cinematic realism for today’s
leading-edge games like Doom III™ from id Software and Abducted
from Contraband Entertainment.” –NVIDIA
