1. A concise explanation of the problem you’re experiencing.
I’d like to know if a Cartesian3 point is inside a boundingsphere, is it possible?
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
let boundingSphere = new Cesium.BoundingSphere(bdCenter, radius);
let point = Cesium.Cartesian3.fromDegrees(longitude, latitude);
/// I should check in point is inside boundingsphere
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
I’m expanding the boundingsphere on the basis of the camera view, and I should know if the camera is looking to a point that is inside this boundingsphere
4. The Cesium version you’re using, your operating system and browser.
