description Computer graphics real-time rendering technology is developing rapidly. During the development process, the requirements for rendering realism and speed are getting higher. Physics-based rendering (PBR) uses a more physical way to simulate light, which can achieve a more realistic rendering effect and improve the reliability of rendering algorithm. In the core sampling part of PBR algorithm, a large amount of precomputation is required. To improve the computational efficiency, this paper proposes a precomputation-based Sobel algorithm with uniform spherical sampling method from the diffuse light irradiance map of PBR algorithm, which uses the Sobel algorithm with better uniformity to generate low differential sequences and uniform spherical sampling to obtain the sampling vector. In terms of sampling efficiency, it is better than the traditional sampling method. Compared with the original algorithm, the improved algorithm has basically the same rendering effect under the premise of improving reliability, and can be better used for real-time rendering.
