Geometrical Models for Substitutions [PDF]
Experimental Mathematics, 2011 We consider a substitution associated with the Arnoux-Yoccoz interval exchange transformation (IET) related to the tribonacci substitution. We construct the so-called stepped lines associated with the fixed points of the substitution in the abelianization (symbolic) space. We analyze various projections of the stepped line, recovering the Rauzy fractal,

L-systems in Geometric Modeling [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 We show that parametric context-sensitive L-systems with affine geometry interpretation provide a succinct description of some of the most fundamental algorithms of geometric modeling of curves.

Advanced Modeling and Simulation in Engineering Sciences, 2020 This paper proposes an extension of the finite cell method (FCM) to V-rep models, a novel geometric framework for volumetric representations. This combination of an embedded domain approach (FCM) and a new modeling framework (V-rep) forms the basis for ...

Geometric models of matter [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Inspired by soliton models, we propose a description of static particles in terms of Riemannian 4-manifolds with self-dual Weyl tensor. For electrically charged particles, the 4-manifolds are non-compact and asymptotically fibred by circles over physical 3-space.

Reverse Engineering-Inspired Parametric 3D Geometry Model of Marine Propeller
Polish Maritime Research, 2023 In this study, an effective parametric 3D geometry model of a propeller was established with the aid of reverse engineering. The goal is to reduce the free parameters while automating the modelling of the propeller. The process of building the parametric
