WPF3D关于HelixToolkit-3D呈现的交互处理
关于HelixToolkit-这个3D呈现的交互处理推荐使用，因为功能比较强大一个开源3D库，根据MIT许可证获得许可。MIT许可证非常宽松，允许在专有软件中使用。该库基于 .NET，目前专注于 WPF 平台。HelixToolkit是.NET Framework的一个开源3D图形库，它主要用于创建和操作3D图形1。HelixToolkit包含许多实用的3D图形工具，例如3D视图、3D模型、3D场景、3D渲染、3D动画等，它们可以帮助开发者快速创建出高质量的3D图形应用程序1。HelixToolkit的文档和教程可以在官方网站上找到，开发者可以根据需要查看和使用地址：https://github.com/helix-toolkit Nuget安装<Grid><h:HelixViewport3D ShowViewCube="True"
