THREE-DIMENSIONAL COMPUTER GRAPHIC SYSTEM

摘要

PROBLEM TO BE SOLVED: To simplify the data processing job that is needed for arranging the attendant objects on the main body surface of a three-dimensional shape according to a prescribed arranging method. SOLUTION: The texture information including the arrangement information on the attendant objects included in the texture image data is stored in a texture information storage part 106 in order to obtain the shape data on the attendant objects which are adaptive to the three-dimensional shape of a main body based on the mapping information showing the correspondence between the main body surface of a three-dimensional shape and the texture image data, the three-dimensional shape information on the attendant objects and the arrangement information on the attendant objects. Then the arrangement information included in the texture information corresponding to the mapping information read at a mapping information reading part 103 is read at an attendant object three-dimensional shape information reading part 107. A conversion part 105 converts the attendant object three-dimensional shape information for arrangement of the attendant objects based on the mapping information and the arrangement information. Thus, the shape data on the attendant objects are obtained.
