Constants

const ENU_FRAME

Frame constant for the East-North-Up (ENU) coordinate frame, with X pointing east, Y pointing north, and Z pointing up (away from the ellipsoid surface).

const CAMERA_FRAME

Frame constant for a camera-convention frame relative to the ENU frame, oriented with "+Y" up and "-Z" forward (matching three.js camera conventions).

const OBJECT_FRAME

Frame constant for an object-convention frame relative to the ENU frame, oriented with "+Y" up and "+Z" forward (matching three.js object conventions).
