| getCoords(lat, lng [,altitude]) | Utility method to translate spherical coordinates to cartesian. Given a pair of latitude/longitude coordinates and optionally altitude (in terms of globe radius units), returns the equivalent {x, y, z} cartesian spatial coordinates. |
| getScreenCoords(lat, lng [,altitude]) | Utility method to translate spherical coordinates to the viewport domain. Given a pair of latitude/longitude coordinates and optionally altitude (in terms of globe radius units), returns the current equivalent {x, y} in viewport coordinates. |
| toGeoCoords({ x, y, z }) | Utility method to translate cartesian coordinates to the geographic domain. Given a set of 3D cartesian coordinates {x, y, z}, returns the equivalent {lat, lng, altitude} spherical coordinates. Altitude is defined in terms of globe radius units. |
| toGlobeCoords(x, y) | Utility method to translate viewport coordinates to the globe surface coordinates directly under the specified viewport pixel. Returns the globe coordinates in the format { lat, lng }, or null if the globe does not currently intersect with that viewport location. |
