基于UE4的铁路货车转向架三维交互仿真系统模型优化的研究及实现

Research and Implementation of the Model Optimization of 3D Interactive Simulation System for Railway Truck Bogie Based on UE4

本文研究了在虚幻引擎4(UE4)中如何优化货车转向架模型进行虚拟现实(VR)技术展示。在UE4中模型的优化质量直接决定了在VR中的交互效果。对于结构复杂、模型精细的机械结构,模型的面数通常十分庞大,在UE4中处理的数据增加,会导致画面卡顿、交互系统反馈延时,无法达到实时性。因此本文将解决基于UE4为开发平台,导入Solidworks、UG、Proe等软件创建的Nurbs模型,并在UE4中进行模型优化,以满足在UE4中达到实时性和交互性的技术要求。打通模型由CAD工业软件到UE4虚幻引擎的通道,节省模型转化的时间,提高研究效率。同时在军用仿真训练系统、科学研究和科学计算可视化、教育、培训、娱乐、商业和医学应用等各领域模拟仿真交互中提供了模型优化的方法。

This article examines how to optimize the bogie model for VR(Virtual Reality)technology presentation in Unreal Engine 4(UE4).In UE4,the optimization quality of the model directly determines the interaction effect in VR,for the mechanical structure with complex structure and fine model,the number of faces of the model is usually very large,and the data to be processed in UE4 increases,resulting in screen stuttering,feedback delay of the interactive system,and cannot achieve real-time.Therefore,this article will solve the Nurbs model created based on UE4 as the development platform,import solidworks,UG,Proe and other software,and optimize the model in UE4 to meet the technical requirements of achieving real-time and interactivity in UE4.Open up the channel from CAD industrial software to UE4 Unreal Engine,save the time of model transformation,and improve research efficiency.At the same time,it provides model optimization methods in various fields such as military simulation training systems,scientific research and scientific computing visualization,education,training,entertainment,business and medical applications.
