3D model deformations with arbitrary control points
(2016-06-01)
Article
Open AccessCage-based space deformations are often used to edit and animate images and geometric models. The deformations of the cage are easily transferred to the model by recomputing fixed convex combinations of the vertices of the ... -
3D triangular mesh to represent the left ventricle volume of the heart
(2002-07-01)
Research report
Open AccessThis report describes an algorithm for the generation of unstructured tetrahedral meshes from two triangular meshes: the internal and external walls of an object. The tetrahedral mesh thus obtained represents the volume ... -
A general illumination model for molecular visualization
(2018-06)
Article
Open AccessSeveral visual representations have been developed over the years to visualize molecular structures, and to enable a better understanding of their underlying chemical processes. Today, the most frequently used atom-based ... -
A multi-projector CAVE system with commodity hardware and gesture-based interaction
(2017-01-12)
Research report
Open AccessSpatially-immersive systems such as CAVEs provide users with surrounding worlds by projecting 3D models on multiple screens around the viewer. Compared to alternative immersive systems such as HMDs, CAVE systems are a ... -
A Parser-based tool to assist instructors in grading computer graphics assignments
(European Association for Computer Graphics (Eurographics), 2019)
Conference report
Open AccessAlthough online e-learning environments are increasingly used in university courses, manual assessment still dominates the way students are graded. Interactive judges providing a pass/fail verdict based on test sets are ... -
A Survey on curve and surface fairing
(1998-09)
Research report
Open AccessSculptured or free-form surface design is a broadly used tool in industry. This report studies the existing automatic fairing methods for curves and surfaces. A classification is established and advantages and drawbacks ... -
A Tool for N-way analysis of programming exercises
(European Association for Computer Graphics (Eurographics), 2020)
Conference report
Open AccessProgramming exercises are a corner stone in Computer Science courses. If used properly, these exercises provide valuable feedback both to students and instructors. Unfortunately, the assessment of student submissions through ... -
A topological comparison of surface extraction algorithms
(2021-10-22)
Research report
Open AccessIn many application areas, it is useful to convert the discrete information stored in the nodes of a regular grid into a continuous boundary model. Isosurface extraction algorithms differ on how the discrete information ... -

Open AccessIn many application areas, it is useful to convert the discrete information stored in the nodes of a regular grid into a continuous boundary model. Isosurface extraction algorithms di er on how the discrete information in ... -
Adaptive on-the-fly molecular ribbons generation
(European Association for Computer Graphics (Eurographics), 2015)
Conference lecture
Open AccessMolecular dynamics simulations are of key importance in the drug design field. One common used representation to visualize these simulations is the Ribbons representation, which gives to the expert a good overview of the ... -
Approximation of a variable density cloud of points by shrinking a discrete membrane
(North Holland, 2005-12)
Article
Restricted access - publisher's policyThis paper describes a method to obtain a closed surface that approximates a general 3D data point set with nonuniform density. Aside from the positions of the initial data points, no other information is used. Particularly, ... -
Approximation of a variable density cloud of points by shrinking a discrete membrane
(2002-12)
Research report
Open AccessThis paper describes a method to obtain a closed surface that approximates a general 3D data point set with non-uniform density. Excluding the initial data points, any other previous information is not used (as, for ... -

Automatic code generation for ATLAS communications drivers
(1999-12)
Research report
Open AccessATLAS is a software development platform created in our Department. Among other benefits, it provides support to easily distribute applications over a network. In these applications, communications issues among the different ... -
Biharmonic fields and mesh completion
(2015-11)
Article
Open AccessWe discuss bi-harmonic fields which approximate signed distance fields. We conclude that the bi-harmonic field approximation can be a powerful tool for mesh completion in general and complex cases. We present an adaptive, ... -
Classification of a point with respect to a polyhedron vertex

Computing maximal tiles and application to impostor-based simplification
(North Holland, 2004-08)
Article
Restricted access - publisher's policyThe computation of the largest planar region approximating a 3D object is an important problem with wide applications in modeling and rendering. Given a voxelization of the 3D object, we propose an efficient algorithm to ...
