Ship emergency drills require high-fidelity restoration, multi-risk scenario reproduction, and high efficiency. Virtual simulation modeling technology possesses high-fidelity 3D modeling capabilities, enabling it to break through physical constraints and achieve repeatable and immersive drills in multi-risk scenarios. Therefore, a study on the application and path optimization of virtual simulation-based ship emergency drill technology is carried out. By integrating 3ds Max and Unity 3D, a full-element 3D refined model is constructed, encompassing virtual humans (Virtual Human), ships, and fire emergency scenarios. The cellular automaton and particle system are employed to conduct dynamic simulation of flame spread and visualize fire smoke. A path search method that combines an improved A* algorithm with navigation meshes is utilized, and a control behavior algorithm is introduced to drive the movement of virtual humans, thereby achieving intelligent optimization of evacuation and roaming paths. The results demonstrate that this technology can construct realistic and clear high-fidelity full-element 3D models, search for evacuation and roaming paths that effectively avoid obstacles, and keep the path search time within 25 ms, meeting the requirements of ship emergency drills.
