PROBLEM TO BE SOLVED: To provide a data generation method for three-dimensional graphics capable of displaying a three-dimensional graphics for a practical use even when a three-dimensional graphic system with a relatively low processing performance is used. SOLUTION: This is a method for obtaining data for a three-dimensional CG by sequentially reading an object data 10 and a scene data 11 frame by frame (S1), processing the data read at the step S1 by an arithmetic operation including a geometric operation and a light source calculation (S2-S6), and further optimally processing the data (S7, S8) so that the three-dimensional CG data is reduced in the volume based on the hardware restriction conditions including those relating to the processing performance of the three-dimensional graphic system. |
