    • Efficient Sampling of Textured Scenes in Vertex Tracing 

      Ullmann, Thomas; Preidel, Thomas; Bruderlin, Beat (Eurographics Association, 2003)
      We present vertex tracing, an adaptive progressive ray tracing approach for efficient sampling of the radiance function, based on refinement in object space and subsequent reconstruction, using standard 3D graphics accelerator ...

    • Uncertainty Visualization Methods in Isosurface Rendering 

      Rhodes, Philip J.; Laramee, Robert S.; Bergeron, R. Daniel; Sparr, Ted M. (Eurographics Association, 2003)
      We describe two techniques for rendering isosurfaces in multiresolution volume data such that the uncertainty (error) in the data is shown in the resulting visualization. In general the visualization of uncertainty in data ...

    • Implicit Surface Reconstruction and uniform Sampling by Striped Marching Triangles 

      Leborán, Víctor; Pardo, Xose M. (Eurographics Association, 2003)
      The synthesis of computer models from real objects is a usual procedure in medical image processing and reverse engineering. In both cases, the main issues are to reach a topologically consistent and geometrically precise ...

    • Inelastic Scattering and Participating Media.Application to the ocean 

      Cerezo, Eva; Seron, Francisco J. (Eurographics Association, 2003)
      A system, developed to treat general participating media, is generalized to make it capable of considering volumetric inelastic processes such as fluorescence. The system is based on the discrete ordinates method, and can ...

    • High quality images from 2.5D video 

      Berretty, Robert-Paul; Ernst, Fabian (Eurographics Association, 2003)
      Given a 2D video stream with an accompanying depth channel, we render high quality images from viewpoints close to the original one. This is for instance required to generate a 3D impression on stereoscopic or multiview ...

    • Reconstruction of Animatable Personalized 3D Faces by Adaptation-based Modeling 

      Zhang, Yu; Sim, Terence; Tan, Chew Lim (Eurographics Association, 2003)
      We present an efficient method for the construction of an animatable 3D facial model of a specific person with minimal user interaction. The method is based on adapting an anatomy-based prototype facial model that is ...
