Hoops Fusion: Synthesis of View-dependent Convex Occluders from a Set of Objects
(The Eurographics Association, 2022)Visibility determination is a requirement to navigate through complex scenes. Occluder fusion algorithms generate convex occluders that are contained in the umbra cast by a group of objects given an area light. Hoops are ... -
INTERCOMUNICANDO - Computer Assisted Communication for Severely Handicapped Persons
(The Eurographics Association, 2022)This paper presents project INTERCOMUNICANDO whose aim is to provide computer assisted pictogram based communication as a rehabilitation toolfor severely handicapped persons. The project developed a suite of integrated ... -
Marching Edges: A Method for lsosurface Extraction
(The Eurographics Association, 2022)Volumetric data can be represented as a rectilinear structured grid and can be displayed by the rendering of an isosurface that is built from the grid and defining a threshold value. The know marching cubes method builds ... -
MIXDesign, Tangible Mixed Reality for Architectural Design
(The Eurographics Association, 2022)MIXDesign, provides a tangible Mixed-Reality system oriented towards tasks in Architectural Design, in severa! usage scenarios, such as Conceptual Design, Client Brief or even Architectural Design education. With MIXDesign, ... -
Oetermining orientation of Laser scanned surfaces
(The Eurographics Association, 2022)Real 3D data acquired from scanning technology provide interesting 3D models for research and industrial applications. However before these models can be used, a surface needs to be jitted to a point cloud of an unknown ... -
Optimal Software-based Projector Alignment
(The Eurographics Association, 2022)We present a software-based method for alignment of projectors, both for side-by-side (mosaic) and stereo projections. The projectors are assumed to be positioned in such a way that their axes are not perpendicular to the ... -
Powering Multiprojection lmmersive Environments with Clusters of Commodity Computers
(The Eurographics Association, 2022)Multiprojection lmmersive Environments are used in many fields such as science, engineering and art. Virtual Reality (VR) oriented systems have been powered traditionally by high-end graphics workstations or supercomputers ... -

Simulating E-Garments Oressed on Personalísed Avatars
(The Eurographics Association, 2022)We present a general computational architecture that solves the problem of the production of physical-based virtual textiles and garments (so called electronic garments or e-garments), applicable in lnternet-based ... -
Sketching User Interfaces with Visual Patterns
(The Eurographics Association, 2022)This paper presents an approach to layout static components of user interfaces as hand-drawn compositions of simple geometric shapes, using sketch recognition and visual languages. The system uses a visual grammar built ... -
Surface Collision Detection for Maintenance Support in Virtual Environments
(The Eurographics Association, 2022)Detecting collision between surfaces is an important feature for supporting interactive assembly operations based on the geometric constraint-based simulation. CAD models define the geometry of components using surfaces ... -
Towards Content-Based Retrieval of Technical Orawings through High-Oimensional lndexing
(The Eurographics Association, 2022)This paper presents a new approach to classify, index and retrieve technical drawings by content. Our work uses spatial relationships, visual elements and high-dimensional indexing mechanisms to retrieve complex drawings ... -
Towards Fully Reconfígurable Multimedia Platforms
(The Eurographics Association, 2022)This paper describes a novel approach to implement multimedia access platforms: reconfigurable oriented codesign. Nowadays we observe a rapid and mutant evolution of multimedia standards and its de facto adoption into many ... -
A Virtual Collaborative Learning Environment
(The Eurographics Association, 2022)This paper presents a virtual learning environment developed for music education and includes both individual and collaborative interactive environments. This learning environment is a music composition edutainment software, ... -
Virtual Reality in Cooperative Teleoperation
(The Eurographics Association, 2022)Virtual reality enables to build systems that enhance communication by facilitating information display. ln teleoperation applications, virtual reality improves task performance thanks to intuitive manipulation and exploration ... -
Visualization Techniques in a Building Potential Simulator Using Sunlíght Access Con
(The Eurographics Association, 2022)This paper presents the use of a technique known as solar envelope in the simulation of building potential of urban plots as well as the improvement of 2D and 3D visualization techniques of simulation results. The consideration ...
