PROBLEM TO BE SOLVED: To suppress discontinuity between a two-dimensional(2D) image and the peripheral objects of 3D virtual reality world by deforming the 2D image while using a novel pyramid-shaped panel structure, and adjusting the disappear point of the image corresponding to the move of a user. SOLUTION: A screen/panel is divided into four triangular areas 145-1 to 145-4. The point, where four areas cross, is located at a disappear point P (S140). A current viewpoint V of the user is determined and a vector T-is projected from an ideal viewpoint IVP toward the current position V of the user. Each time the user moves, a new disappear point P' is calculated according to the relational expression of P'=P+T-. Four triangular areas 145-1 to 145-4 are deformed inside the 3D space of 3D virtual world (S155). The texture mapping of correspondent images displayed in the areas 145-1 to 145-4 is respectively performed on the pyramid-shaped panels 145-1 to 145-4 (S160). |
