摘要: |
为了提高基于OGRE三维仿真引擎对牵引供电系统进行三维仿真时的实时渲染效率,从减少渲染批次的角度出发,对仿真模型加载优化方法进行研究。通过分析普通模型加载方式(单个物体独立加载)、静态几何加载方式和实例几何加载方式的工作原理,并以牵引供电系统绝缘子为实验对象,分别采用三种加载方式加载不同数量的绝缘子进行对比分析,结果表明静态几何和实例几何方法能够大幅地减少渲染批次,相比于普通的加载方式可以大大地提高渲染效率。根据三种加载方式的特点,设计了仿真系统的模型加载优化方案,仿真结果表明提出的优化方案对牵引供电系统进行仿真可以减少实时渲染过程中的批次,有效地提高场景的实时渲染效率。 |

Abstract: |
In order to improve the real time rendering efficiency of three-dimensional simulation of traction power supply system based on the three-dimensional simulation engine of OGRE, from the perspective of reducing rendering batches, the simulation model loading optimization method is researched. Working principles of the normal model loading method (single object independent loading), the static geometry loading method and the instanced geometry loading method are analyzed. The three different loading methods are used to load amount of insulators of traction power supply system respectively, the result shows that compared with the normal loading method, the static geometry loading method and the instanced geometry loading method can significantly reduce the number of rendering batches and greatly improve the rendering efficiency. According to the characteristics of the three kinds of loading methods, model loading optimization scheme of the traction power supply system is designed, the simulation results show that the optimization scheme proposed here can reduce the number of batches in real time rendering and effectively improve the real time rendering efficiency. |
