旋转及缩放模型核心代码

if(rx){const mx = Cesium.Matrix3.fromRotationX(Cesium.Math.toRadians(rx));const rotate= Cesium.Matrix4.fromRotationTranslation(mx);Cesium.Matrix4.multiply(m, rotate, m);}if(ry){const my = Cesium.Matrix3.fromRotationY(Cesium.Math.toRadians(ry));const rotate= Cesium.Matrix4.fromRotationTranslation(my);Cesium.Matrix4.multiply(m, rotate, m);}if(rz){const mz = Cesium.Matrix3.fromRotationZ(Cesium.Math.toRadians(rz));const rotate= Cesium.Matrix4.fromRotationTranslation(mz);Cesium.Matrix4.multiply(m, rotate, m);}if(scale){const _scale = Cesium.Matrix4.fromUniformScale(scale);Cesium.Matrix4.multiply(m, _scale, m);}tileSet._root.transform = m;
