A novel approach to represent 3-D isothetic scenes using XYZ trees

XYZ-tree is a hybrid data structure between object space and volume enumeration representation schemes. It is useful for isothetic polygons/polyhedrons and rectangles/rectangular parallelopipeds in 2/3-d. It is a compact and efficient data structure for representing city scape, VLSI circuits, printed circuit boards, etc. Trees may be combined using Boolean operators.
