METHOD OF GEOMETRIC SIMPLIFICATION OF 3D POLYGONAL OBJECTS Тозик В. Т., Alexander Mezhenin
The article deals with the method of geometric simplification of 3D polygonal object models for reducing the amount of data that leads to an increase in the rates of both transmission and visualization. The proposed simplification method of the three-dimensional polygonal objects uses edge collapse operations. Additional checks are aimed for eliminating the effect of a degenerate polygonal mesh. To assess the quality of polygonal network simplification the Hausdorff dimension is proposed to use.
