WebIn addition, call the distance between the camera and the two points L. The camera's field of view ( F O V) (or angle of view as is more common in photography) can be calculated by. F O V = 2 arctan ( d 2 F) which, for a scene at distance L corresponds to a scene dimension W equal to. W = 2 ⋅ L ⋅ tan ( F O V / 2) = L d F. Web31 de jan. de 2013 · Each geometry has a computeBoundingBox function. So you can do: var bbox = geometry.computeBoundingBox (); for each geometry that you are interested in and then use the bbox.center () to get the center of your geometry.
