数字孪生马来西亚建筑接口【压缩】
更新时间：2025-10-30 14:00:15
接口说明
该接口用于获取马来西亚槟城指定版本和细节层级的3D Tiles数据，返回JSON格式的瓦片集描述文件。
调用方式
请求参数
无
返回参数
返回值为：tileset.json ，一个 JSON 格式的文件，通常用于定义三维瓦片集（Tileset）的结构和属性。
属性详情：
asset：规范版本和工具信息。
properties：瓦片集的全局属性（如坐标系、单位、扩展字段）
boundingVolume：瓦片的物理/地理范围，用于空间查询和裁剪。
geometricError：控制瓦片渲染细节的误差值（值越大，加载的瓦片越粗糙）。
refine：瓦片细化策略，参数：ADD：叠加子瓦片到父瓦片（渐进增强），REPLACE：用子瓦片替换父瓦片。
content.uri：指向瓦片数据文件（如 .b3dm（瓦片压缩模型）、.glb（瓦片压缩模型））。
children：子瓦片集合（递归结构）
