A Study on Natural 3D Shape Manipulation in VR
(The Eurographics Association, 2018)
Current immersive modeling environments use non-natural tools and interfaces to support traditional shape manipulation operations. In the future, we expect the availability of natural methods of interaction with 3D models ...
CageLab: an Interactive Tool for Cage-Based Deformations
(The Eurographics Association, 2018)
Posing a digital character by acting on the vertices of a coarse control cage is, after skeleton-based, probably the most widely used technique for digital animation. While skeleton-based techniques have been deeply ...
Simplification of Shapes for Fabrication with V-Groove Milling Tools
(The Eurographics Association, 2018)
We introduce here a pipeline for simplifying digital 3D shapes with the aim of fabricating them using 2D polygonal flat parts. Our method generates shapes that, once unfolded, can be fabricated with CNC milling machines ...
Indicators Basis for Functional Shape Analysis
(The Eurographics Association, 2018)
Step functions are widely used in several applications from geometry processing and shape analysis. Shape segmentation, partial matching and self similarity detection just to name a few. The standard signal processing tools ...
Computational Fabrication of Macromolecules to Enhance Perception and Understanding of Biological Mechanisms
(The Eurographics Association, 2019)
We propose a fabrication technique for the fast and cheap production of 3D replicas of proteins. We leverage silicone casting with rigid molds, to produce flexible models which can be safely extracted from the mold, and ...
Feature-based Characterisation of Patient-specific 3D Anatomical Models
(The Eurographics Association, 2019)
This paper aims to examine the potential of 3D shape analysis integrated to machine learning techniques in supporting medical investigation. In particular, we introduce an approach specially designed for the characterisation ...
HT-based Recognition of Patterns on 3D Shapes Using a Dictionary of Mathematical Curves
(The Eurographics Association, 2019)
Characteristic curves play a fundamental role in the way a shape is perceived and illustrated. To address the curve recognition problem on surfaces, we adopt a generalisation of the Hough Transform (HT) which is able to ...
Recognition, Modelling and Interactive Manipulation of Motifs or Symbols Represented by a Composition of Curves
(The Eurographics Association, 2020)
In this work we introduce a method for the recognition, modelling and interactive manipulation of graphical motifs, symbols or artistic elements that are represented by a composition of plane curves. Our method bases on ...
A First Step Towards Cage-based Deformation in Virtual Reality
(The Eurographics Association, 2020)
The advent of low cost technologies makes the use of immersive virtual environments more interesting for several application contexts. 3D models are largely used in such environments for providing feelings of immersion and ...
Approximating Shapes with Standard and Custom 3D Printed LEGO Bricks
(The Eurographics Association, 2021)
In this paper, we present a work-in-progress aimed at developing a pipeline for the fabrication of shapes reproducing digital models with a combination of standard LEGO bricks and 3D printed custom elements. The pipeline ...
