| Abstract: | In this paper,the theories of spherical harmonics(SH) and its properties are studied,and the spatial geometric structures and characteristics of SH are displayed in several ways intuitively.As a kind of linear basis,the SH function is applied to the pre-computed process of the light transport.The rendering effects can be improved by optimizing the properties of the existing algorithms.And the real-time controlling of certain illumination environment can be realized with the required rendering speed. |
