Abstract
An environment includes different objects that are each made up of one or more 3-dimensional volumes. These volumes can overlap one another, resulting in situations in which a particular volume that is overlapped is redundant and can be removed from the set of volumes describing the environment. A two-phase approach is applied in determining whether a particular volume is redundant. In the first phase, a candidate list of source volumes is quickly generated with a small amount of computational effort. In the second phase, the source volumes on the candidate list are analyzed to determine whether the particular volume is fully overlapped by one or a combination of the source volumes.
