Coordinate information updating device

摘要

An object can be displayed on a screen of a two-dimensional coordinate system based on xyz-coordinate values of the object in a three-dimensional coordinate system, operation information of a two-dimensional coordinate system with respect to the object can be received from an input device, and whether the operation information is in accordance with a predetermined rule or not is determined. If the operation information is not in accordance with the predetermined rule, xy-coordinate values of the object can be updated in accordance with the operation information. If the operation information is in accordance with the predetermined rule, a z-coordinate value of the object can be updated in accordance with the operation information.

1. A system, comprising:
a storage unit configured to store a coordinate value of an object in a three-dimensional coordinate system, the object configured to be displayed on a two-dimensional display; an input interface configured to receive operation information of a two-dimensional coordinate system, the operation information usable to update xy-coordinate values of the three-dimensional coordinate system with respect to the object; an operation information determination unit configured to determine whether the operation information is in accordance with a particular rule; and an update unit configured, based on a result of the determination of the operation information determination unit, to: update the xy-coordinate values of the three-dimensional coordinate system with respect to the object in accordance with the operation information, in response to the operation information not being in accordance with the particular rule, and update a z-coordinate value of the three-dimensional coordinate system with respect to the object in accordance with the operation information to adjust a shape or position of the object in a z-coordinate direction and not update the xy-coordinate values of the three-dimensional coordinate system, in response to the operation information being in accordance with the particular rule.
