Methods and systems for determining lighting values, including providing a set of points around a 3D geometry, the set of points being independent of the 3D geometry, determining a depth map of the 3D geometry with respect to a view point by projecting the 3D geometry according to the view point, and determining visibility values for the set of points by comparing the set of points to the depth map of the 3D geometry.
