Title: Implicit-surface processing method
Inventor: NAKASE JUNKO
IPC: G06T15/40
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide an implicit-surface processing method capable of executing an exact implicit-surface processing with less processing quantity in a three- dimensional graphics processing. SOLUTION: Representative values of X, Y, Z coordinates to represent objects are calculated from apex coordinates of plural polygons to constitute the objects (100), position relation between respective objects is fixed by comparing the representative values of the X, Y, Z coordinates of respective obtained objects and a Z buffer application area is extracted (102). When overlap of the representative values is detected in all of three directions as X, Y, Z, the implicit-surface processing (210) is performed by a Z buffer method and when no overlap is detected, the implicit-surface processing (202) by overwriting is performed. Thus, the area in which a Z buffer is used is reduced to the absolute minimum, comparison between values of Z coordinates and an update processing by using the Z buffer is reduced.
