Ultimately, the innovative techniques combined in NVIDIA’s UltraShadow II technology will empower developers with more programming flexibility and the hardware muscle they need to create unprecedented effects in their games and 3D applications. ![]() UltraShadow II also works perfectly with NVIDIA® Intellisample™ technology to ensure that shadow edges are properly antialiased.Īdvanced games use UltraShadow II to create photorealistic shadows, contributing to compelling digital experiences. With the ability to fine-tune shadows within critical regions, developers create incredible visualizations that mimic reality, and still achieve awesome performance for fast-action games. By defining a bounded portion of a scene (called "depth bounds"), and focusing calculations only on the area most affected by the light source, developers can greatly accelerate the shadow generation process. Today’s leading-edge game developers want to design complex digital light sources and realistic shadows, as illustrated in this scene from DOOM 3.Īdditionally, NVIDIA UltraShadow II gives developers the ability to calculate shadows much more quickly by eliminating unnecessary areas from consideration. The technology advancements in UltraShadow II also deliver a 4× performance increase (compared to the previous generation) for passes involving shadow volumes. Thus, emerging next-generation games, that employ multiple light sources with many visible objects in each scene-such as DOOM 3™ from id Software-will see dramatic improvements in execution speeds. With UltraShadow II hardware, the more passes that are required for the lighting and shadow calculations in a scene, the more significant the performance improvement, with the most complex scenes achieving the most noticeable results. With a system powered by a GeForce 6 or GeForce 7 Series GPU, anytime a game or application calculates shadows, UltraShadow II will enhance the overall performance. ![]() The NVIDIA® GeForce™ 6 and GeForce 7 Series of GPUs deliver the patent-pending NVIDIA® UltraShadow™ II technology, which can be applied to today’s games to build stunning visual effects and to create distinctive digital environments. For every frame in a game, every light source must be analyzed relative to every object, potentially bogging down the PC and affecting your gameplay. ![]() But the complex interactions between light sources, objects, and characters involve elaborate programming. Accurate shadows are critical for realistic and believable scenes in games.
