Abstract
A method of rendering a three-dimensional point cloud in a two-dimensional display includes inputting the three-dimensional point cloud that includes three-dimensional coordinates of a set of points, creating a depth buffer for the three-dimensional point cloud that includes depth data for the set of points from a viewpoint location. The method further includes determining a foreground depth buffer by, for each respective pixel area of the two-dimensional display, determining a foreground depth by detecting a closest point to the viewpoint location among a subset of the set of points corresponding to the respective pixel area, and assigning a depth of the closest point as the foreground depth for the respective pixel area. The method further includes filtering the depth buffer to obtain a filtered depth buffer by removing points that are not in the foreground, and outputting the filtered depth buffer to the two-dimensional display.
