A special sub-family of polygon partition problems arises when the large polygon is a rectilinear polygon (also called: orthogonal polygon). In this case, the most important component shape to consider is the rectangle. Rectangular partitions have many applications. In VLSI design, it is necessary to decompose masks into the simpler shapes available in lithographic pattern generators, and similar mask de… WebIn this case, consider processing input data by partition by identifying a relevant polygon feature class in the Cartographic Partitions environment setting. Portions of the data defined by partition boundaries will be processed sequentially.

WebJust as the simplest polygon is the triangle, the simplest polyhedron is the tetrahedron: a pyramid with a triangular base. We can generalize the 2D notion of polygon triangulation to 3D: a tetrahedralization of a polyhedron is a partition of its interior into tetrahedra whose edges are diagonals of the polyhedron.
