摘要

薄壳模型是指物体的厚度可以忽略不计的表面或结构。在三维打印中,薄壳模型的特点是重量轻、中空结构和材料用量少。薄壳模型的多功能性和视觉吸引力使其在布料仿真、人物皮肤制作以及树叶、纸张或金属片等薄壁结构等多个领域大受欢迎。然而,由于薄壳的内部操作空间极小,对无外部支撑的薄壳模型进行优化仍是一项挑战。出于同样的原因,掏空方法也不适合这项任务。事实上,薄壳调制方法需要保留双面表面的视觉外观,这进一步限制了问题空间。在本文中,我们针对薄壳模型引入了一种新的视觉差异度量,从视觉感知的角度整合了局部细节和整体形状属性。我们的方法利用全局变形和局部增厚来调节薄壳模型,同时考虑视觉显著性、稳定性和结构完整性。因此,薄壳模型(如浮雕、空心形状和布料)可以稳定地站在任意方向上,非常适合三维打印。

Shell stand: Stable thin shell models for 3D fabrication

A thin shell model refers to a surface or structure, where the object’s thickness is considered negligible. In the context of 3D printing, thin shell models are characterized by having lightweight, hollow structures, and reduced material usage. Their versatility and visual appeal make them popular in various fields, such as cloth simulation, character skinning, and for thin-walled structures like leaves, paper, or metal sheets. Nevertheless, optimization of thin shell models without external support remains a challenge due to their minimal interior operational space. For the same reasons, hollowing methods are also unsuitable for this task. In fact, thin shell modulation methods are required to preserve the visual appearance of a two-sided surface which further constrain the problem space. In this paper, we introduce a new visual disparity metric tailored for shell models, integrating local details and global shape attributes in terms of visual perception. Our method modulates thin shell models using global deformations and local thickening while accounting for visual saliency, stability, and structural integrity. Thereby, thin shell models such as bas-reliefs, hollow shapes, and cloth can be stabilized to stand in arbitrary orientations, making them ideal for 3D printing.
