Image generating device and information storage medium
First Claim
1. An image generating device generating an image seen from a given viewpoint in an object space, comprising:
- an operating means for inputting movements of a player;
means for performing calculation to move at least one moving body along a course in object space based on at least a first force being a force corresponding to kinetic energy of the movements of the player input by the operating means and a second force being a force pulling along a travel direction of the course in object space; and
means for generating an image seen from a given viewpoint in object space.

Abstract
The object is the provision of an image generating device and information storage medium such that even a player of low strength or the like can smoothly move a moving body in an object space. Based on a pedaling force PF corresponding to kinetic energy input using pedals, and a course attractive force AF pulling in the direction of progress along a course in object space, a moving body is moved along the course in the object space. The kinetic energy is obtained, for example, by a player moving an operating means with a hand or foot. The course is given vertical relief, and moving body is moved based on PF, AF, and gravity. When the moving body is on a level ground, or when the pedals are not being turned the course attractive force AF is disabled. In the case of a multi-player game in which a plurality of moving bodies are moving, the magnitude of the course attractive force AF is varied according to the distance from the moving body in first position or the rank order of the moving bodies. The present invention can be applied to a bodily sensing game such as a bicycle, boat, or animal racing game.
