Quantifying the Geometric Shell Shape between Populations of True Limpets Lottia Mesoleuca (Mollusca: Lottidae) in Colombia

open access: yesAnimals, 2020
The increasing activity in morphological studies has provided new tools to analyses the shape quantitatively, these quantitative measurements allow the researcher to examine the variation in shape and perform analysis to examine the quantitative ...

On Geometric Shape Construction via Growth Operations [PDF]

open access: yesTheoretical Computer Science, 2022
In this work, we investigate novel algorithmic growth processes. In particular, we propose three growth operations, full doubling, RC doubling and doubling, and explore the algorithmic and structural properties of their resulting processes under a geometric setting.

Wire mesh design [PDF]

open access: yes, 2014
We present a computational approach for designing wire meshes, i.e., freeform surfaces composed of woven wires arranged in a regular grid. To facilitate shape exploration, we map material properties of wire meshes to the geometric model of Chebyshev nets.

Design of general-purpose sampling strategies for geometric shape measurement [PDF]

open access: yes, 2011
Quality inspection is a preliminary step for different further analyses (process monitoring, control and optimisation) and requires one to select a measuring strategy, i.e., number and location of measurement points.

Planar shape manipulation using approximate geometric primitives [PDF]

open access: yes, 2012
We present robust algorithms for set operations and Euclidean transformations of curved shapes in the plane using approximate geometric primitives. We use a refinement algorithm to ensure consistency.

A COMPARATIVE STUDY ABOUT CARS’ LOGOS

open access: yesJournal of Industrial Design and Engineering Graphics, 2019
In this paper, we have considered as a challenge to answer to the question: Why is so important a logo for a car? Because, as we know, we can identify a car or, in many cases, a car manufacturer, only by seeing its logo.

Second-order Shape Optimization for Geometric Inverse Problems in Vision [PDF]

open access: yes, 2014
We develop a method for optimization in shape spaces, i.e., sets of surfaces modulo re-parametrization. Unlike previously proposed gradient flows, we achieve superlinear convergence rates through a subtle approximation of the shape Hessian, which is ...
