GPU Gems 2: Programming Techniques for High-Performance Graphics and General-Purpose Computation

Chapter 27. Advanced High-Quality Filtering

Justin Novosaddiscreet

Advanced filtering methods have been around for a long time. They were developed primarily for scientific applications such as analyzing MRIs and satellite images. Thanks to recent advances in GPU technology, these methods can be made available to PC users who simply want their computer graphics to look as nice as possible.

This chapter provides a general overview of GPU-based texture-filter implementation issues and solutions, with an emphasis on texture interpolation and antialiasing problems. We explore a series of high-quality texture-filtering methods for rendering textured surfaces. These techniques can be used to perform several common imaging tasks such as resizing, warping, ...
