转发:用cesium做了个雨量插值,有兴趣的可以看看
viewer.scene.globe.depthTestAgainstTerrain = true时标绘会被遮挡,false 时标绘会随着视角,飘动,既不想被遮挡,也不想随视角变换移动,怎么破?
Cesium.Math.setRandomNumberSeed(1234);
var viewer = new Cesium.Viewer('cesiumContainer', { infoBox : false });
var entities = viewer.entities;

});
entities.add({

cesium加载kml数据,大概2000条,从官网上考的。请问官网为什么加载后那么流畅,我的cesium加载后就内存不足崩溃了?
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?
