Research on Unity Scene Optimization Based on Fast LoD Technique Performance Comparison on Android Mobile Platform

With the completion of Unity scene development, it is often necessary to publish the scene on all platform for different user communities to operate. However, due to the insufficient hardware performance of Android mobile devices, in order to provide players with a smoother operation experience, developers will optimize the scene before final release. This article elaborates on the process of optimizing models in a certain scene through fast LoD technique based on QEM algorithm. It demonstrates that simplifying mesh grids of models can effectively improve the smoothness of scene operation and reduce device resource consumption. Through comparative analysis, it is concluded that the fast LoD technique can achieve higher optimization efficiency and better optimization effects than common LoD technique, and it has brought better performance and experience improvement to scene operation.
