Information processing method and apparatus for deposition

Abstract

An object of this invention is to enable to appropriately carry out deposition due to a design change of an object. This invention comprises the steps of: calculating a difference between three dimensional data representing a form of an object before a design change and three dimensional data representing a form of the object after the design change; and generating deposition data for a shortage portion in the form of the object before the design change by using the calculated difference data, when cutting the object to make the form after the design change. Thus, it is possible to correctly grasp information concerning the deposition necessary to machine the object to make the form after the design change, and to avoid waste of deposition material and cutting work after the deposition. Moreover, this invention may further comprise a step of calculating a region for one or a plurality of deposition layers based on an attribute of a deposition material. Because the maximum thickness of one deposition layer or the like differs according to the attribute of the deposition material, it is useful in the deposition process to obtain regional information for each layer when the deposition is carried out by putting the deposition layers on top of each other.
