Cesium点击实体，修改参数实现实体的平移和旋转

primitives类型的实体（针对3DTileset）

复制代码

//旋转
            let mx = Cesium.Matrix3.fromRotationX(Cesium.Math.toRadians(Number(this.form.x)));
            let my = Cesium.Matrix3.fromRotationY(Cesium.Math.toRadians(Number(this.form.y)));
            let mz = Cesium.Matrix3.fromRotationZ(Cesium.Math.toRadians(Number(this.form.z)));
            let rotationX = Cesium.Matrix4.fromRotationTranslation(mx);
            let rotationY = Cesium.Matrix4.fromRotationTranslation(my);
            let rotationZ = Cesium.Matrix4.fromRotationTranslation(mz);
            //平移
            //let position = Cesium.Cartesian3.fromDegrees(Number(this.form.left), Number(this.form.right), Number(this.form.up));
            let cartesian = new Cesium.Cartesian3(this.model.position.x + Number(this.form.left), this.model.position.y + Number(this.form.right), this.model.position.z + Number(this.form.up))
            //let m = Cesium.Transforms.eastNorthUpToFixedFrame(position);
            let m = Cesium.Transforms.eastNorthUpToFixedFrame(cartesian)
            //旋转、平移矩阵相乘
            Cesium.Matrix4.multiply(m, rotationX, m);
            Cesium.Matrix4.multiply(m, rotationY, m);
            Cesium.Matrix4.multiply(m, rotationZ, m);
            console.log(this.model)
            //赋值给tileset
            this.model._root.transform = m;

其中关于平移的部分要注意，如果你输入的是经纬度，直接用注释里面的代码即可，如果你输入的多少米多少米，用我这部分即可。另外再注意一下，你点击获取的实体信息中是不存在这个"position"这个字段的，这个字段是我自己创建实体的时候添加上去的，这个尤其要注意

entity类型的实体（如glb）

复制代码

let position = this.model.position._value
            //旋转
            let heading = Cesium.Math.toRadians(this.form.x)
            let pitch = Cesium.Math.toRadians(this.form.y)
            let roll = Cesium.Math.toRadians(this.form.z)
            let hpr = new Cesium.HeadingPitchRoll(heading, pitch, roll)
            let orientation = Cesium.Transforms.headingPitchRollQuaternion(position, hpr)
            this.model.orientation._value = orientation
            //平移
            let cartesian = new Cesium.Cartesian3(position.x + Number(this.form.left), position.y + Number(this.form.right), position.z + Number(this.form.up))
            this.model.position._value = cartesian
            //缩放
            this.model.model.scale._value = this.form.scale

注意，这时候的model应该是点击地图要素获取的id不是上面那个primitive这两个要区分
