遍历加载osgb模型，只有最后一个模型加载成功。大神帮忙看看吧

我有一个3d tiles模型贴不到地上来，其他模型都可以，就这个不行，设置都是一样的，有没有人遇到过类似的问题，也不报错，有没有什么办法可以调试？

请问各位大牛有没有方法生成osgb的LOD？

用超图的desktop 9d将obj转换为osgb后，发现没有osgb的LOD，只有一个比较大的osgb文件，加载很慢

淹没分析不就是给entity贴个水的材质，然后动态升高？

测试了，不支持vive的

cesium加载geoserver发布的epsg:4326的tms服务，不知道为啥出不来？求指教

当离散的距离线段比较小的时候，应该就是匀速的了，可以试试。

是这个吗？不管用啊

如果不在模型制作那边操作的话，可以用代码控制加载吗

ie下不支持从笛卡尔坐标系中获取添加的实体和位置信息

确实是遮挡了 我花了两条线和一个wall -> 1条悬空的线 一条贴地的线 中间是墙 cesium有没有类似于padding的属性呢

加高度是不是就成立体的了

Cesium.Ion.defaultServer="http://127.0.0.1:9080/version.json";

version.json这个文件要有

Cesium.Ion.defaultServer 把这个地址换成自己的就可以

隐藏实体： viewer.entities.getById("rain").show = false;
