| description | To enable partially regulating physical properties of a three-dimensional shape without changing the quality of a fabrication material.SOLUTION: A generation device 10 of three-dimensional shape data expresses a three-dimensional shape by a plurality of voxels, and acquires three-dimensional shape data in which a physical property value is set in each of the plurality of voxels. The generation device sets a three-dimensional threshold value matrix in which threshold values are arranged in a three-dimensional region corresponding to a predetermined basic shape, and calculates presence/absence of fabrication for each of the plurality of voxels on the basis of the plurality of physical property values of voxels and the three-dimensional threshold value matrix.SELECTED DRAWING: Figure 1
【課題】造形材料の材質を変更せずに三次元形状の物性を部分的に調整することができる。【解決手段】三次元形状データの生成装置１０は、三次元形状を複数のボクセルで表すと共に、複数のボクセルの各々に物性値が設定された三次元形状データを取得し、予め定めた基本形状に対応して閾値が三次元領域に配置された三次元閾値マトリクスを設定し、複数のボクセルの物性値と、三次元閾値マトリクスと、に基づいて、複数のボクセルの各々について造形の有無を算出する。【選択図】図１ |
