How to Determine whether the feature is in the current view

CesiumJS

I now have 3D Tiles of the pipe network. I want to determine whether each pipe, i.e. feature, is in the current field of view. Is there any good way to do this?

getViewExtend() {
let params = {};
let extend = viewer.camera.computeViewRectangle();

    //3D获取方式
    params.maxx = Cesium.Math.toDegrees(extend.east);
    params.maxy = Cesium.Math.toDegrees(extend.north);

    params.minx = Cesium.Math.toDegrees(extend.west);
    params.miny = Cesium.Math.toDegrees(extend.south);

    return params; 
};

[/quote]Thanks！This is the rectangular area of ​​the camera’s view, but the feature has no boundingVolumn. How can I tell whether it is in the camera’s view?
