    Procedural modeling of virtual cities has achieved high levels of realism with little effort from the user. One can rapidly obtain a large city using off-the-shelf software based on procedural techniques, such as the use ...
  • Transient Photon Beams 

    Marco, Julio; Jarosz, Wojciech; Gutierrez, Diego; Jarabo, Adrian (The Eurographics Association, 2017)
    Recent advances on transient imaging and their applications have opened the necessity of forward models that allow precise generation and analysis of time-resolved light transport data. However, traditional steady-state ...
  • Procedural Generation of Natural Environments with Restrictions 

    Gasch, Cristina; Chover, Miguel; Remolar, Inmaculada (The Eurographics Association, 2017)
    Natural environments are a very important part of virtual worlds, both for video games and for simulators, but their manual creation can be a very expensive job. The procedural creation of these, allows to generate them ...
  • Tree Variations 

    Argudo, Oscar; Andújar, Carlos; Chica, Antoni (The Eurographics Association, 2017)
    The cost-effective generation of realistic vegetation is still a challenging topic in computer graphics. The simplest representation of a tree consists of a single texture-mapped billboard. Although a tree billboard does ...
  • Transfer Learning for Illustration Classification 

    Lagunas, Manuel; Garces, Elena (The Eurographics Association, 2017)
    The field of image classification has shown an outstanding success thanks to the development of deep learning techniques. Despite the great performance obtained, most of the work has focused on natural images ignoring other ...
  • An Interactive Tool for Modeling Ancient Masonry Buildings 

    Fita, Josep Lluis; Besuievsky, Gonzalo; Patow, Gustavo (The Eurographics Association, 2017)
    We present a new pipeline of an interactive tool that combines procedural modeling of ancient masonry buildings with structural simulation. The tool has been designed for taking an input geometry of an ancient building and ...
  • Fast Stippling based on Weighted Centroidal Voronoi Diagrams 

    Gómez, Eila; Méndez, Elías; Arroyo, Germán; Martín, Domingo (The Eurographics Association, 2017)
    Stippling is an artistic technique that has been used profusely in antiquity. One of the main problems is that it requires great skill and patience to achieve excellent results due to the large number of points that must ...
  • Improved Intuitive Appearance Editing based on Soft PCA 

    Malpica, Sandra; Barrio, Miguel; Gutierrez, Diego; Serrano, Ana; Masia, Belen (The Eurographics Association, 2017)
    During the last few years, many different techniques for measuring material appearance have arisen. These advances have allowed the creation of large public datasets, and new methods for editing BRDFs of captured appearance ...
  • Direct Volume Rendering of Stack-Based Terrains 

    Graciano, Alejandro; Rueda, Antonio J.; Feito, Francisco R. (The Eurographics Association, 2017)
    Traditionally, the rendering of volumetric terrain data, as many other scientific 3D data, has been carried out performing direct volume rendering techniques on voxel-based representations. A main problem with this kind ...
  • Downsampling and Storage of Pre-Computed Gradients for Volume Rendering 

    Díaz-García, Jesús; Brunet, Pere; Navazo, Isabel; Vázquez, Pere-Pau (The Eurographics Association, 2017)
    The way in which gradients are computed in volume datasets influences both the quality of the shading and the performance obtained in rendering algorithms. In particular, the visualization of coarse datasets in multi-resolution ...
