o thousands of objects are often displayed in scenes, without a GPU those objects have to share the limited processing power of the CPU, forcing software developers to budget processing tasks. Now with an NVIDIA GPU transform calculations are offloaded from the CPU, allowing more detailed objects with higher polygon counts to be processed more quickly. With transformation a jungle scene can have lots of trees and bushes—rather than just a single tree—and each tree can consist of many leaves created by thousands of polygons. Since the GPU relieves the CPU of the burden of calculating the transforms, you will be able to view scenes rich with complex objects that look real and move like their real-life counterparts. Not only will the objects and characters be complex, but many more can exist. How does lighting work?The human eye is more sensitive to changes in brightness than it is to changes in color—which means that an image with lighting effects communicates more information to a viewer more efficiently. The discrete lighting engine on an NVIDIA GPU calculates distance vectors from lights to objects and from objects to a viewer's eyes within 3D scenes. Lighting calculations are an effective way to add both subtle and not-so-subtle changes in brightness to 3D objects in a manner that mimics real-world lighting conditions. 32-bit Z-Buffer/StencilThe GeForce2 Ultra uses 32-bit Z-Buffer/Stencil technology .Double Data RateThe GeForce2 Ultra most notable feature is its speed. The card features 64MB of Double Data Rate SGRAM (DDR). DDR allows for data to be fetched on both the rising and falling edges of the clock thus doubling the effective transfer rate of the clock, the ability at which the memory is able to collected by processor. The 64MB of DDR has a clock speed of 233MHZ, but because of it’s ability to send information on the rising and falling edges of the clock it really has a clock speed of 466MHz. 32-bit...
