Abstract
A method of sight distance analysis comprising: acquiring a scene-graph representation comprising three dimensional entities; acquiring at least one three dimensional object representation within the scene graph environment; acquiring a target object representation; selecting at least one camera position; positioning the acquired target object representation in the scene graph representation at a distance from the selected at least one camera position; and determining a visibility factor for the positioned target object representation.
