Introduction
Developers of 3D graphics applications have always had difficulty creating realistic computer generated characters, objects and environments that can be interacted with in real time. The limitation has been a lack of available processing power combined with the restricted flexibility afforded by existing graphics hardware. There has always been a trade-off between performing operations on the CPU, which allows more flexibility due to its general and programmable nature, and the graphics processor, which allows better performance due to its hardwired and heavily optimized architecture. While the rapidly increasing speed of graphics processors has enabled a significant amount of progress, and while they have been steadily taking over many of the tasks formerly handled by the CPU, there are many interesting and useful graphical techniques that have remained out of reach
because they require a combination of speed and flexibility that neither existing CPUs or graphics processors could adequately provide.What is needed is a technology that combines the speed and optimizations of a dedicated graphics processor with the flexibility and programmability of a CPU, allowing a virtually infinite range of visual effects at interactive frame rates. The first attempts at introducing this kind of technology were successful in increasing the number of effects available to developers, but still suffered from a number of limitations in terms of both versatility and performance. SMARTSHADER technology, developed by ATI, removes these limitations to free developers imaginations
