Abstract:
An object movement apparatus, comprising:a collision arithmetic unit performing arithmetic including a detection of two closest points in accordance with information representative of a plurality of objects, among an object of interest of any one of the plurality of objects and other objects except the object of interest, said two closest points consisting of a closest point on a closest object located closest to the object of interest with respect to the object of interest, and a closest point on the object of interest with respect to the closest object; andan image producing unit producing a three-dimensional image including a virtual object representative of a closest line coupling the two closest points to each other in response to movement of one of the plurality of objects,wherein said image producing produces the three-dimensional image by changing the viewpoint from a first viewpoint before the movement to a second viewpoint after the movement such that the second viewpoint is determined by passing a plane normal to the closest line through a mid-point of the closest line, by forming a line normal to the plane and connecting the plane to the first viewpoint, and by defining the second viewpoint at a point on a line connecting the midpoint and the point of connection of the line normal to the plane.
