Object operation device, method, and computer-readable storage medium storing object operation program

摘要

An object operation device for operating an object displayed on a display device, the object operation device includes a coordinate system generation unit that generates a local coordinate system for each of a plurality of points set around a reference object that is a reference of an operation when a target object is moved three-dimensionally by the operation, a move destination coordinates calculation unit that calculates move destination coordinates of the target object corresponding to a move command value of the target object inputted through an input device based on the local coordinate system of each of the generated plurality of points, and a moving process unit that moves the target object to the calculated move destination coordinates.

1. An object operation device for operating an object displayed on a display device, the object operation device comprising:
a coordinate system generation unit that generates a plurality of local coordinate systems respectively corresponding to a plurality of points set around a reference object that is a reference of an operation when a target object is moved three-dimensionally by the operation; a move destination coordinates calculation unit that calculates move destination coordinates of the target object corresponding to a first move command value of the target object inputted through an input device, based on a first local coordinate system corresponding to a first point that is nearest to a coordinate of the target object among the plurality of points; and a moving process unit that moves the target object to the calculated move destination coordinates, wherein the coordinate system generation unit obtains a potential value according to a distance from the reference object, and generates the local coordinate system for each of the plurality of points set in the form of a grid around the reference object, based on first, second, and third axes, the first axis being orthogonal to an isosurface formed by linking together the points having the equal potential values, the second and third axes being orthogonal to each other on the isosurface.
