| Abstract(in English) | Splitting cell problem is an important problem in computational geometry, spatial database and constraint database areas. Spatial operations such as union, difference, and intersection is based on splitting cell with some hyper planes. This paper presents an algorithm to split bounded and unbounded spatial objects with hyperplanes in any dimension. The previous algorithm only works for bounded objects because it assumes that all HA-face has more than 2 sub-HA-faces. This algorithm considers the number of sub-HA-faces in the evaluation process and applies different face splitting algorithm. This algorithm also create position vector. This make it possible to compute an unbounded cells. This paper presents the implementation, and evaluations. |
