Game program for calculating the vertex information of the triangle polygon, a recording medium storing it, and the game device

摘要

PPROBLEM TO BE SOLVED: To provide a game program for adjusting the displacement quantity of one vertex information at the time of generating one vertex information from two vertex information and a recording medium for storing the game program and a game device, and to provide a game program for generating the vertex whose detail level is high from the vertex whose detail level is low. PSOLUTION: This game program is configured to make a computer function as a means which calculates the vertex information(for example, Y components representing the height of vertexes) of a triangular polygon. At the time of dividing one first triangular polygon into four second triangular polygons, a means for calculating vertex information calculates one vertex information (YSB13/SB) among six vertex information configuring those four second triangular polygons by using displacement quantity from an intermediate value between the two vertex information (YSB1/SB, YSB2/SB) among the three vertex information configuring the first triangular polygon, that is, displacement quantity based on random numbers. It is desired that the displacement quantity is adjusted by a plurality of levels representing the strength of the displacement quantity. PCOPYRIGHT: (C)2005,JPO&NCIPI
