Abstract: The optimization of traditional three-dimensional simulation model is time-consuming, laborious, occupying a large amount of memory and losing frames and reporting errors in rendering. Targeting these problems, this paper proposes a three-dimensional lightweight modeling method based on selfish herd intelligent optimization algorithm, called 3DL-SHO, according to the type of redundancy of three-dimensional model, which intelligently reduces the amount of scene data, speeds up the optimization of the model, and facilitates mapping baking on the basis of ensuring the accuracy of three-dimensional data. The optimization experiments of BIM system and power plant three-dimensional simulation system show that all batch operations of 3D Max can be executed quickly and efficiently through the proposed method implemented by MAXScript, which greatly improves the efficiency of modeling and optimization.
