```auto
new Cesium.Geometry({
        attributes: {
          //几何顶点属性
          position: new Cesium.GeometryAttribute({
            componentDatatype: Cesium.ComponentDatatype.DOUBLE, //数据类型
            componentsPerAttribute: 3, //定义几个为一组
            values: positions, //坐标值
          }),
          // st: new Cesium.GeometryAttribute({
          // componentDatatype: Cesium.ComponentDatatype.FLOAT, //数据类型
          // componentsPerAttribute: 2, //定义几个为一组
          // values: sts, //坐标值
          // }),
          color: new Cesium.GeometryAttribute({
            componentDatatype: Cesium.ComponentDatatype.FLOAT,
            componentsPerAttribute: 4,
            values: colors,
          }),
          alpha: new Cesium.GeometryAttribute({
            componentDatatype: Cesium.ComponentDatatype.FLOAT,
            componentsPerAttribute: 1,
            values: thas.alpha,
          }),
        },
        indices: positionIndex,
        //POINTS TRIANGLE_STRIP TRIANGLES
        primitiveType: Cesium.PrimitiveType.TRIANGLES,
        boundingSphere: Cesium.BoundingSphere.fromVertices(positions), //包围球
      })

```

is 3dtile have way to get custom data in shader like this?
