Save camera position

CesiumJS

I want to save camera position on scene, what props do i need to save (with headingpitchrange) and how to restore position? I did read similar topics, but they are outdated and doesnt work.

I guess you need to save and restore camera position and orientation.

// save
const camera = viewer.camera;
const cameraPositionCartographic = camera.positionCartographic;

let view = {
    longitude: CesiumMath.toDegrees(cameraPositionCartographic.longitude),
    latitude: CesiumMath.toDegrees(cameraPositionCartographic.latitude),
    height: cameraPositionCartographic.height,
    heading: CesiumMath.toDegrees(camera.heading),
    pitch: CesiumMath.toDegrees(camera.pitch),
    roll: CesiumMath.toDegrees(camera.roll)
};

const jsonView = JSON.stringify(view);

// restore
view = JSON.parse(jsonView);

const destination = Cartesian3.fromDegrees(view.longitude, view.latitude, view.height);
const orientation = {
    heading: CesiumMath.toRadians(view.heading),
    pitch: CesiumMath.toRadians(view.pitch),
    roll: CesiumMath.toRadians(view.roll)
};

viewer.camera.flyTo({
    destination,
    orientation
});

I’ve tried do the same but with wrong orientation i guess, so it doesnt work:

...

orientation: {
  direction: new Cartesian3(direction.x, direction.y, direction.z),
  up: new Cartesian3(up.x, up.y, up.z),
},

...

Your example do the thing, thank you
