srbf version 1.0 Designed and Developed by: Tien-Tsin Wong Chi-Sing Leung Ping-Man Lam T. Y. Ho

Introduction

Unlike the complex spherical harmonics, a spherical radial basis function (SRBF) lighting framework is introduced to achieve real-time ultra-realistic rendering. It is mathematical simpler, intuitive, computational efficient and easy to learn. Its visual quality is comparable to spherical harmonics.

For more information about the brief idea of SRBF, please refer to our GDC 2007 presentaton. For further references, please refer to the related publication at the bottom of this page.
