摘要

PROBLEM TO BE SOLVED: To realize three-dimensional display fitted to shape understanding at high speed while interactivity is maintained at the time of performing an interactive operation such as a visual point change operation in display of a three-dimensional model.;SOLUTION: A calculation part 1 calculates an area value of a plotting region when the three-dimensional shape is projected on a two-dimensional region. The calculated area value of the plotting region is stored in a storage part 2. An order of display when the three-dimensional shape is displayed is sorted in a sorting part 3 in accordance with the stored area value and a visual point which is set in a visual point setting part 4. The three-dimensional shape is displayed in accordance with a sorted order in a display part 5.;COPYRIGHT: (C)2004,JPO
