Part IV. Image Processing
When most people think of GPU power, they focus on purely 3D applications, yet the pictures we actually see on our monitors are 2D. Programmable pixel shaders provide personal computers with unprecedented image-processing power, extending our abilities for both 2D and 3D development.
Graphic designers and illustrators have long used complex controls in still-image photo-editing applications, but such programs can process only one picture at a time. The newest GPUs can perform these previously slow operations at interactive rates, allowing us to apply the full power of complex compositing and color-control applications not ...
