|1. (WO2018221722) 3D MODEL GENERATION DEVICE, 3D MODEL GENERATION METHOD, 3D MODEL GENERATION PROGRAM, STRUCTURE, AND STRUCTURE MANUFACTURING METHOD|
|Applicants:||THE UNIVERSITY OF TOKYO
|Title:||3D MODEL GENERATION DEVICE, 3D MODEL GENERATION METHOD, 3D MODEL GENERATION PROGRAM, STRUCTURE, AND STRUCTURE MANUFACTURING METHOD|
Provided is a 3D model generation device that generates 3D model data of a structure which has a cross-section shape that is suited to layered shaping and which has a density distribution that continuously changes according to the amount of voids. The 3D model generation device comprises: a determination unit that determines the value of a first parameter which varies spatially so that the value decreases as the density of a structure 100 increases and the value increases as the density decreases; and a generation unit that generates, in accordance with an inequality containing a periodic function in which the value is determined depending on the first parameter using a coordinate value that indicates a point in space as a variable, 3D model data which designates whether to layer a shaping material at the point in space.
