      In this paper, we present an extension of the Locally Controlled Spot Noise and a visualization pipeline for volumetric fuzzy details synthesis. We extend the noise model to author volumetric fuzzy details using filtered ...
    • Volumetric Textures 

      Gonzalez Clua, Esteban W.; Dreux, Marcelo (Eurographics Association, 2000)
      There are some types of nature elements that are adequately represented in Computer Graphics only through volumes. In order to visualize scenes with volumes, together with geometrical objects, it is necessary to make use ...
    • A Volumetric Virtual Environment for Catheter Insertion Simulation 

      Zorcolo, Antonio; Gobbetti, Enrico; Zanetti, Gianluigi; Tuveri, Massimiliano (The Eurographics Association, 2000)
      We present an experimental catheter insertion simulation system that provides users co-registered haptic and head-tracked stereoscopic visual feedback. The system works on patient-specific volumetric data acquired using ...
    • Volumetric Visualization Techniques of Rigid and Deformable Models for Surgery Simulation 

      Herrera Asteasu, Imanol (Herrera Asteasu, 2013-10-15)
      Virtual reality computer simulation is nowadays widely used in various fields, such as aviation, military or medicine. However, the current simulators do not completely fulfill the necessary requirements for some fields. ...
    • VolumeViewer: An Interactive Tool for Fitting Surfaces to Volume Data 

      Sowell, R.; Liu, L.; Ju, T.; Grimm, C.; Abraham, C.; Gokhroo, G.; Low, D. (The Eurographics Association, 2009)
      Recent advances in surface reconstruction algorithms [BM07,LBD08] allow surfaces to be built from contours lying on non-parallel planes. Such algorithms allow users to construct surfaces of similar quality more efficiently ...
    • A Voronoi based Labeling Approach to Curve Reconstruction and Medial Axis Approximation 

      Peethambaran, Jiju; Parakkat, Amal Dev; Muthuganapathy, Ramanathan (The Eurographics Association, 2015)
