@admin #5楼 大神可以帮我看下哪里不对吗。 var a = Cesium.Matrix4.fromArray(tileset._root.transform); var s = Cesium.Matrix4.getTranslation(a, new Cesium.Cartesian3); var _s = Cesium.Transforms.eastNorthUpToFixedFrame(s); var angle = Cesium.Matrix3.fromRotationX(90); var modelMatrix =Cesium.Matrix4.multiplyByMatrix3(_s, angle,new Cesium.Matrix4() ); tileset.modelMatrix = modelMatrix;
