Fast Illumination Shading Method for Immediate Radiance Rendering

High realistic rendering has been applied in many fields because it can generate realistic images. However, this kind of rendering needs a lot of computing resources, and it is difficult to achieve real-time speed, it is difficult to meet the needs of real-time application scenarios. Aiming at this problem, this paper proposes a rendering method suitable for real-time display. For the indirect light source coloring part, this paper proposes an image spatial region division to accelerate the rendering structure, which improves the rendering efficiency and avoids the problem caused by insufficient sampling points. Finally, this paper proposes a method based on ambient light shading to eliminate energy over transmission. This method mainly focuses on high-quality rendering under interactive conditions. It can realize scene roaming smoothly under the condition of conventional hardware, making the display object of complex 3D scene more realistic. The method of low-frequency global illumination energy block coloring is used to improve the rendering speed. Compared with the existing methods, our method achieves high realistic real-time rendering of complex models.
