Abstract
A three-dimensional data shaping apparatus defines a working region, as a region of specific size and shape within a reference three-dimensional space, with a corresponding display picture being generated. A user can move the working region, using an input device such as a mouse, to select a specific part of a work object that is represented by a set of constituent data elements within the reference space, and execute shaping of the selected part. Determination of a selected part is performed in two judgement stages, i.e. a first stage in which a judgement is made as to interference between the working region and a number of fixed-size small regions into which the three-dimensional space is considered to be divided, and a second stage in which a judgement is made as to interference between the working region and only those constituent elements of the work object which correspond, according to predetermined criteria, with those of the small spaces for which interference has been found in the first judgement stage.
