Research on 3D rendering effect of substation based on OSG

Substation 3D visualization is one of the important links to realize the digital transformation of China’s power grid. The existing 3D model engine is difficult to meet the real-time state dynamic display of many devices in the complex scene of substation. In this paper, an improved OSG 3D rendering engine for 3D visualization of substation is designed, and a dynamic data interaction method between 3D rendering engine and auxiliary equipment is proposed. The scene management function is optimized, and the optimized mapping and lighting effect models are selected. The experimental results show that the rendering effect of the engine designed in this paper is more real and gorgeous than ordinary OSG, and the processing efficiency is higher, which can meet the needs of 3D visualization display of substation.
