Methods and systems to determine view cell occlusion, including to project objects of a 3-dimensional graphics environment to a 2-dimensional image plane with respect to the view point, to reduce sizes of corresponding object images, to generate an occluder map from the reduced-size object images, to compare at least a portion of the object images to the occluder map, and to identify an object as occluded with respect to the view cell when pixel depth values of the object image are greater than corresponding pixel depth values of the occluder map. Methods and systems to reduce an object image size include methods and systems to nullify pixel depth values within a radius of an edge pixel, and to determine the radius as a distance from the edge pixel to a second pixel so that a line between the view point and the second pixel is parallel with one or more of a line and a plane that is tangential to a sphere enclosing the view cell and a point on the object that corresponds to the edge pixel.
