Three-dimensional (3D) computer simulation models are crucial components in studying remote sensing radiation transmission mechanisms, playing a significant role in forward modeling of complex surfaces and remote sensing inversion. Over the past two decades, remarkable progress has been made in 3D computer modeling research, with widespread applications in analyzing surface radiation transmission processes, validating models and algorithms, and remote sensing inversion. To fully understand the development of 3D computer simulation models, explore the differences between models, and discuss how to better apply them to daily life and production, this paper provides a comprehensive overview of 3D computer simulation models in optical remote sensing. The discussion is structured around three main aspects: model principles, applications, and development trends. Firstly, the principles of ray tracing and radiosity methods, along with existing models, are briefly introduced. Secondly, the primary applications of 3D computer simulation models in remote sensing are summarized. Finally, the future development trends of these models are discussed, analyzing the trends in 3D computer simulation model development and remote sensing applications based on issues and needs related to operational efficiency, simulation accuracy, and functional integration. With the deepening of research on remote sensing modeling of complex surfaces, advancements in computer technology, and the application of multi-source remote sensing data, especially high spatio-temporal resolution data, 3D computer simulation models will play an increasingly important role in both theoretical research and practical applications of remote sensing.
