Wavelet Applications for Rendering

This document explores the intricate applications of wavelet techniques in rendering 3D graphics. It covers the basics of rendering, including direct illumination and path tracing, with notable insights from experts like Ren Ng and Pat Hanrahan from Stanford University. The outline features a detailed review of Haar wavelets, discussion on triple product integrals for all-frequency relighting, and advanced techniques such as wavelet importance sampling. This comprehensive overview aids in understanding how wavelet theory enhances graphic rendering and image quality in modern applications.
