### 说明 ###

因为公司的产品规划，最近在研究数字孪生方向的产品，看到51word的云渲染路线实现三维GIS+游戏引擎的跨界融合手里的超图瞬间不香了；

不过没多久看到超图官网已经出了相应的拓展插件今天准备试试。之前有关注过cesium有和ue公司 宣布合作开发一套基于ue的三维插件实现在ue4中构建三维球加载3dtileset数据 ，不过一直没消息。

基于Cesium for Unreal演示效果: [地址][Link 1]

### 基于UE的效果示例 ###

### 步骤 ###

1. 安装Epic Games软件，安装成功之后注册账号下载安装ue虚幻引擎

备注 : 这里安装的是最新版的4.25 需要将系统的visual studio 升级到2019

2. 超图官网下载super\_ue插件

下载地址:[https://www.supermap.com/en-us/html/down.html][https_www.supermap.com_en-us_html_down.html]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDkwMjUyNw_size_16_color_FFFFFF_t_70 1][]

下载解压里边有bin脚本目录和ue插件目录，需要分别配置和创建，具体详细操作流程在第三个pdf文件中

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDkwMjUyNw_size_16_color_FFFFFF_t_70 2][]

3.下载 supermap-idesktop桌面端和supermap-iserver服务端

这里主要是用于桌面端处理自己的数据切成s3m数据通过isever发布服务，然后通过超图拓展的ue plugin插件加载到ue引擎中

新建工作空间 - 加载数据源 -生成切片缓存 - 发布服务数据

也可以直接发布整个工作空间到iserver上

4.通过前面的配置将超图三维插件导入到ue引擎中，导入基础配置和项目设置等启动

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDkwMjUyNw_size_16_color_FFFFFF_t_70 4][]

5. 使用插件创建关卡可以通过搜索super \* 插件拖动到场景中创建超图的三维服务

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDkwMjUyNw_size_16_color_FFFFFF_t_70 5][]

6. 然后通过supermap\_chinese空间加载三维服务，其他控件详细说明参考pdf文件

加载在线必应底图，点击运行

构建三维球

加载切片服务，这里用的是超图的在线示例数据

没数据。。

看了下文档需要平面数据需要添加xyz坐标然后定位过去

添加超图已经导入的UI控件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDkwMjUyNw_size_16_color_FFFFFF_t_70 9][]

加载scp顶层文件然后定位过去

基本效果

### 基于Unity的效果示例 ###

说明： 安装步骤参考UE4，主要是超图的服务注册，这里不做叙述。
