THREE-DIMENSIONAL DATA MANAGEMENT DEVICE AND THREE-DIMENSIONAL DATA PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To practically reduce voxel data.;SOLUTION: A three-dimensional data management device 10 comprises a combined pattern storage table 12a for storing combinations of model states of lower nodes to an upper node as combined patterns, a combined pattern extraction part 13b for extracting existing combined patterns from hierarchical nodes of octal tree voxel data to the combined pattern storage table 12a, and a data conversion processing part 13c for converting the voxel data into voxel data including pattern data according to the combined patterns stored in the combinatorial pattern storage table 12a.;COPYRIGHT: (C)2007,JPO&INPIT
