Unity zSpace 开发

1.下载 zSpace 开发环境

官网地址

1.1 zCore Unity Package

• zSpace 开发核心
• 必须

1.2 zView Unity Package

• 主要用途：在zSpace设备外接显示屏或投影时，将zSpace设备的3D画面转为2D画面进行展示（zSpace显示3D，外接设备显示2D）
• 按需下载

2. 导入工程

将下载好的 zCore Unity Package 导入到 Unity

3. 发布设置

1. Edit—ProjectSettings—Player—OtherSetting—Rendering—ColorSpace 改为 Gamma
2. Edit—ProjectSettings—Player—OtherSetting—AutoGraphicsAPIforWindows 取消勾选
3. Edit—ProjectSettings—Player—OtherSetting—GraphicsAPIsforWindows-添加OpenGLCore，其他全部删除
   
4. Edit—ProjectSettings—Player—XRSetting 中勾选 Virtual Reality Supported
5. Edit—ProjectSettings—Player—XRSetting—Virtual Reality SDKs 删除其他项添加 Stereo Display (non head-mounted)
   

4.功能实现

4.1 用触控笔来实现对模型的拖拽：
