THREE-DIMENSIONAL SHAPE DATA CAPACITY REDUCTION APPARATUS, THREE-DIMENSIONAL ANIMATION REPRODUCER, THREE-DIMENSIONAL SHAPE DATA CAPACITY REDUCTION METHOD, THREE-DIMENSIONAL ANIMATION REPRODUCTION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for reducing and simplifying three-dimensional shape data by using three-dimensional animation data to be embedded in an electronic document. SOLUTION: The apparatus is for reducing a capacity of the three-dimensional shape data constituting three-dimensional animation and has: a means for reading three-dimensional the shape data and animation data; a means for analyzing the animation data to detect a possibility for reducing parts model included in a three-dimensional model; a means for analyzing the animation data to detect a possibility for simplifying the parts model included in the three-dimensional shape model; a means for deleting the parts model which can be deleted to reconstruct the whole three-dimensional model; a means for executing the simplification processing to the parts model which can be simplified to reconstitute the whole of the three-dimensional model; a means for inputting a line of sight direction of low use frequency in an interactive way; and a means for adding to the animation data information on a point of view to be unused.
