Question

为什么设置了贴地还是没有效果呢？？模型还是会跟着视角移动

  const url = "/model/springTree.s3m";
              const postitionSM = new Cesium.Cartesian3.fromDegrees(Number(object.lon), Number(object.lat), Number(object.height));
              const s3mInstanceColc = new Cesium.S3MInstanceCollection(viewer.scene.context);
              viewer.scene.primitives.add(s3mInstanceColc);

              s3mInstanceColc.add(url, {
                position: postitionSM,
                clampToObject: true
              })
