Chapter 24. High-Quality Filtering
Kevin Bjorke NVIDIA
GPU hardware can provide fast, filtered access to textures, but not for every texel format, and only with a few restrictive types of texture filtering. For many applications, building your own image-filtering method provides greater quality and flexibility. Understanding the quality and speed trade-offs between hardware and procedural filtering is crucial for these applications.
The same considerations used for filtering images apply also to 3D rendering, especially when models are textured: we are transforming 3D data (and potentially texture information) into a new 2D image. Understanding this transformation is key to drawing antialiased images.
Hybrid filtering approaches, which use hardware ...
