PROBLEM TO BE SOLVED: To display splash state without increasing loads and without impairing virtual reality by displaying plural polygons to which a texture for expressing a splash is stuck at different angles. SOLUTION: One polygon provided with vertexes 0-3 is successively enlarged. Further, to the polygon, a splash pattern is stuck. A transparent texture is stuck to the polygon other than an area where the splash pattern is stuck. For the splash pattern, in the case of the splash of snow, the texture for expressing the splash of the snow whose base tone is white is stuck. One polygon to which the splash pattern is stuck is enlarged and successively displayed. Thus, the pseudo state of successively spreading the splash is displayed. By repeating the enlargement of the display polygon and the change of a display angle, a splash state with movement is displayed. |
