A new approach to simplify orthogonal pseudo-polyhedra
(OPP) and binary volumes is presented. The method is incremental and
produces a level-of-detail (LOD) sequence of OPP. Any object of this
sequence contains the previous objects and, therefore, it is a bounding
orthogonal approximation of them. The sequence finishes with the minimum
axis-aligned bounding box (AABB). OPP are represented by the
Extreme Vertices Model, a complete model that stores a subset of their
vertices and performs fast Boolean operations. Simplification is achieved
using a new approach called merging faces, which relies on the application
of 2D Boolean operations. We also present a technique, based on the
model continuity, for a better shape preservation. The method has been
tested with several datasets and compared with two similar methods.
