内容优化

The main part of any virtual scene is geometry: meshes imported from 3rd party editor and objects created by means of UnigineEditor and built-in tools (e.g., Terrain, Grass, Water). Using objects with complex geometry and/or a great number of objects as is usually leads to application performance drop. In addition, irrational use of light sources can also raise performance issues. 任何虚拟场景的主要部分都是几何体：从第三方编辑器导入的网格以及通过UnigineEditor和内置工具（例如Terrain, Grass, Water）创建的对象。通常，使用具有复杂几何形状和/或大量对象的对象会导致应用程序性能下降。另外，不合理地使用光源也会引起性能问题。

Articles in this section describe main methods that can be used to optimize geometry and lighting in your scene, and, therefore, increase the performance of your project.本节中的文章介绍了可用于优化场景中的几何形状和照明并因此提高项目性能的主要方法。

注意

To check the performance status of the current scene, use the Performance Profiling Tools. This tool can give you a hint of what you should do to improve the performance.要检查当前场景的性能状态，请使用性能分析工具。该工具可以提示您应该如何提高性能。
