Abstract: In a game device (301) for showing to a player the directions in which movement may be possible in a game where a character is moved between objects in a virtual world, an input receiving unit (305) receives an instruction input for moving a character within the object where the character is located or to another object, an index calculation unit (303) calculates an index indicating the degree to which movement will fail in a case where movement from the object where the character is located to another object is presumed, an image display unit (304) that displays an image associated with the calculated index in a location associated with the direction of the other object, and a character moving unit (306) that moves the character on the object where the character is located, or moves the character to another object, or fails to move the character to another object.

Abstract: A parts model storage unit (203) stores a plurality of parts models. A combination data storage unit (204) stores combination data prescribing a combination part composed by combining the parts models. A contour generation unit (201) generates a contour of each cell for arrangement of parts. The parts arrangement evaluation unit (205) evaluates whether the prescribed combination part can be arranged on each cell, and stores the combination data or the like that are evaluated as being arrangeable, to an arrangement candidate storage unit (206). A parts selection unit (207) selects one combination part from combination data or the like stored in the arrangement candidate storage unit (206). Then, the image rendering unit (208) renders a three-dimensional image in which the selected combination part is arranged on a cell.

Abstract: A parts selection unit (203) reads out outline information stored in an outline information storage unit (212) and selects a parts image in alignment with stored outline information. Then the parts selection unit (203) selects remaining parts so that the total work load is within a range not exceeding a predetermined allowable value, based on stored indicator information. That is, with the processing loads of successively selected parts image being calculated in the processing load calculation unit (204), a remaining parts image is selected. Image rendering unit (206) generates a three-dimensional image based on each parts image selected by the parts selection unit (203) and stored in a map storage unit (205).

Abstract: A lighting model storage unit (205) stores therein a lightning model in which a light source is provided to a model body. A parts selection unit (203) reads an outline shape stored in an outline information storage unit (201) and selects a combination of parts to be arranged to the outline shape from the parts images stored in the parts storage unit (202). A map storage unit (204) stores therein a map where the selected parts are arranged to the outline shape. A lightning model applying unit (206) applies a lightning model matching the map. An image drawing section (207) draws a three-dimensional image on the map where the parts are arranged by combining the cooler components from the light source according to the applied lighting model.

A graphics data generating processor computes the post-movement position coordinates of objects in a virtual three dimensional space, modifies the post-movement position coordinates of objects calculated thereby such that the position coordinates are kept inside a display area in which the objects are displayed, and a rendering processor renders the objects inside the display area.

Abstract: Vertices of a polygon model M0 are sorted into those on which rays are projected (visible-surface vertices M01) and those on which rays are not projected (hidden-surface vertices M02) based on normal vectors V2 of the vertices of the polygon model M0 and a light source vector V1, and shadow models (shadow volumes) M1, M2, M3 are generated by moving the hidden-surface vertices in a direction of the light source vector V1. Shadow images can be easily created by applying stenciling to these shadow models.
