Abstract:
1. A computer-readable storage medium storing a program used for generating an image of an object space viewed from a given viewpoint, the program causing a computer to function as: a contact event determination section which determines whether or not a contact event in which a first model object and a second model object come in contact in the object space has occurred; and a vertex shader section which moves vertices of a contact plane of the second model object with the first model object when the contact event determination section has determined that the contact event has occurred, wherein a given reference plane is set for the first model object, and height information of a surface of the first model object with respect to the reference plane is set in a grid pattern by using height map data; and wherein the vertex shader section fetches the height information of grid points corresponding to a contact plane of the first model object with the second model object by referring to the height map data, and moves the vertices of the contact plane of the second model object based on the fetched height information of the grid points.
