生产线三维可视化解决方案就是通过物联网、虚实联动和三维建模等先进技术，以一个3D立体模型展现出来，可以让我们很直观的看到生产线的运作以及对数据的监控。3D运用数据孪生技术可以让工业3D物联网管理系统的界面变得非常的简单易看，并且能够及时的将异常信息传达给监控人员，以便于监控人员在识别到异常信息的时候能够及时解决问题，从而提高监控效率。

引擎加载（引擎场景、灯光、相机）

生产线仿真

通过Wis3D平台建立生产线数字化模型，动态模拟产线生产过程，快速实现产能验证与产线设计方案的分析并提供优化解决方案。

三维仿真特点：

基于3D生产线规划方案仿真，验证布局方案对产能影响分析

确定生产线极限产能

确定人员需求

仿真确定故障之后生产线的调控应对能力

评估不同生产方案以确定最优最切合实际的方案

确定最合适的生产策略

缓存、设备/人员利用率分析

考虑排产计划、设备OEE、存储区设置以及生产纲领等因素综合评估并给出优化改善建议。

工厂仿真的价值

通过对整个工厂进行仿真，可以及早发现规划中的缺陷和错误，使工厂规划质量得到保证
