“…The complexity of the design process and the variety of quantitative and qualitative factors impacting the quality of a mould make interactive design tools particularly interesting. Among the works listed in the table, only two [NAI*18, SJG19] allow direct user control over the aesthetics and design choices of the mould generation process.…”

“…Stein et al . [SJG19] proposed another interactive tool for the creation of shapes that can be created using a two‐piece mould with a single planar cut. Given the very restrictive constraints of rigid moulding coupled with the requirement of having a single planar cut, arbitrary shapes are commonly unfeasible under these assumptions.…”

Moulding refers to a set of manufacturing techniques in which a mould, usually a cavity or a solid frame, is used to shape a liquid or pliable material into an object of the desired shape. The popularity of moulding comes from its effectiveness, scalability and versatility in terms of employed materials. Its relevance as a fabrication process is demonstrated by the extensive literature covering different aspects related to mould design, from material flow simulation to the automation of mould geometry design. In this state-of-the-art report, we provide an extensive review of the automatic methods for the design of moulds, focusing on contributions from a geometric perspective. We classify existing mould design methods based on their computational approach and the nature of their target moulding process. We summarize the relationships between computational approaches and moulding techniques, highlighting their strengths and limitations. Finally, we discuss potential future research directions.

“…Axis-Alignment in Polycube Maps. Axis-alignment is an important property for many geometry processing tasks, such as [Muntoni et al 2018;Stein et al 2019]. Especially, this concept is one of the main instruments in the construction of polycube maps [Tarini et al 2004], including defining polycube segmentations [Fu et al 2016;Livesu et al 2013;Zhao et al 2018] and the cost function for polycube deformations [Gregson et al 2011;].…”

Fig. 1. Cubic stylization deforms a given 3D shape into the style of a cube while maintaining textures and geometric features. This can be used as a non-realistic modeling tool for creating stylized 3D virtual world. We obtain 3D assets from sketchfab.com by smeerws and Jesús Orgaz licensed under CC BY 4.0.We present a 3D stylization algorithm that can turn an input shape into the style of a cube while maintaining the content of the original shape. The key insight is that cubic style sculptures can be captured by the as-rigidas-possible energy with an ℓ 1 -regularization on rotated surface normals.Minimizing this energy naturally leads to a detail-preserving, cubic geometry. Our optimization can be solved efficiently without any mesh surgery. Our method serves as a non-realistic modeling tool where one can incorporate many artistic controls to create stylized geometries.
