    • Perfect Spatial Hashing for Point-cloud-to-mesh Registration 

      Mejia-Parra, Daniel; Lalinde-Pulido, Juan; Sánchez, Jairo R.; Ruiz-Salguero, Oscar; Posada, Jorge (The Eurographics Association, 2019)
      Point-cloud-to-mesh registration estimates a rigid transformation that minimizes the distance between a point sample of a surface and a reference mesh of such a surface, both lying in different coordinate systems. ...
    • Sensitivity Analysis in Shape Optimization using Voxel Density Penalization 

      Montoya-Zapata, Diego; Acosta, Diego A.; Moreno, Aitor; Posada, Jorge; Ruiz-Salguero, Oscar (The Eurographics Association, 2019)
      Shape optimization in the context of technical design is the process by which mechanical demands (e.g. loads, stresses) govern a sequence of piece instances, which satisfy the demands, while at the same time evolving towards ...
    • Visiting Ancient Rome with a Serious Game 

      Galí, Carlos; Remolar, Inmaculada; Rebollo, Cristina (The Eurographics Association, 2019)
      The current rise of video games has made that different fields of research feel attracted to these new technologies in order to enhance their works and make their results more attractive. It is for this reason that so-called ...
    • Modal Locomotion of C. elegans 

      Mujika, Andoni; Merino, Sara; Leškovský, Peter; Epelde, Gorka; Oyarzun, David; Otaduy, Miguel Angel (The Eurographics Association, 2019)
      Caenorhabditis elegans (C. elegans) is a roundworm that, thanks to its combination of biological simplicity and behavioral richness, offers an excellent opportunity for initial experimentation of many human diseases. In ...
    • A Level-of-Detail Technique for Urban Physics Calculations in Large Urban Environments 

      Novoa, David Muñoz; Besuievsky, Gonzalo; Patow, Gustavo (The Eurographics Association, 2019)
      In many applications, such as urban physics simulations or the study of the solar impact effects at different scales, complex 3D city models are required to evaluate physical values. In this paper we present a new technique ...
    • Procedural Location of Roads Using Desire Paths 

      Real, Pablo; Martínez-Gil, Francisco; Martínez-Durá, Rafael J.; García-Fernández, Ignacio (The Eurographics Association, 2019)
      Procedural modelling of realistic environments that include elements derived from human activity can largely reduce production cost in animation, video-games and feature films. We address the problem of placing roads and ...
    • User-reconfigurable CAD Feature Recognition in 1- and 2-topologies with Reduction of Search Space via Geometry Filters 

      Corcho, Juan Camilo Pareja; Acosta, Oscar Mauricio Betancur; Ruiz, Oscar E.; Cadavid, Carlos (The Eurographics Association, 2019)
      In the context of Computer-Aided Design and Manufacturing, the problem of feature recognition plays a key role in the integration of systems. Until now, compromises have been reached by only using FACE-based geometric ...
    • View-dependent Hierarchical Rendering of Massive Point Clouds through Textured Splats 

      Trinidad, Marc Comino; Calaf, Antonio Chica; Gran, Carlos Andújar (The Eurographics Association, 2019)
      Nowadays, there are multiple available range scanning technologies which can capture extremely detailed models of realworld surfaces. The result of such process is usually a set of point clouds which can contain billions ...
    • Smooth Transitioning Between two Walking Metaphors for Virtual Reality Applications 

      Salvetti, Isadora; Rios, Alex; Nuria, Pelechano (The Eurographics Association, 2019)
      Virtual navigation should be as similar as possible to how we move in the real world, however the limitations of hardware and physical space make this a challenging problem. Tracking natural walk is only feasible when the ...
    • Prototype of an Automatic Registration System for the Remains of Archaeological Sites 

      Ruiz, José Luis López; Alvarado, Lidia Ortega; Higueruela, Francisco Ramón Feito (The Eurographics Association, 2019)
      Data acquisition in archaeological excavations is a time consuming task developed on site that must be completed later with the information stored in the database. In this paper, we introduce the work in progress for the ...
