    • Volumetric Subdivision for Efficient Integrated Modeling and Simulation 

      Altenhofen, Christian (2020-11-05)
      Continuous surface representations, such as B-spline and Non-Uniform Rational B-spline (NURBS) surfaces are the de facto standard for modeling 3D objects - thin shells and solid objects alike - in the field of Computer-Aided ...
    • 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 ...
