3dtiles贴地
作者:互联网
从网上下载的大雁塔和文庙的3dtiles。一个在天空,一个在地下。。
加载模型时设置clamptoground无效。。
var height = 81.5; //根据地形设置调整高度 大雁塔:-420 tileset.readyPromise.then(function(argument) { //贴地显示 var cartographic = Cesium.Cartographic.fromCartesian(tileset.boundingSphere.center); var surface = Cesium.Cartesian3.fromRadians(cartographic.longitude, cartographic.latitude, cartographic.height); var offset = Cesium.Cartesian3.fromRadians(cartographic.longitude, cartographic.latitude, cartographic.height + height); var translation = Cesium.Cartesian3.subtract(offset, surface, new Cesium.Cartesian3()); tileset.modelMatrix = Cesium.Matrix4.fromTranslation(translation); })

//修改高度【独立方法】 // setHeight(height) { // let center = Cesium.Cartographic.fromCartesian(this.tileset.boundingSphere.center); // let surface = Cesium.Cartesian3.fromRadians(center.longitude, center.latitude, center.height); // let offset = Cesium.Cartesian3.fromRadians( // center.longitude, // center.latitude, // center.height + height // ); // let translation = Cesium.Cartesian3.subtract(offset, surface, new Cesium.Cartesian3()); // this.tileset.modelMatrix = Cesium.Matrix4.fromTranslation(translation); // }
