    • 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 ...

    • 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 ...

    • Information Visualization using Transparent Shape Impostors 

      Seipel, Stefan (Eurographics Association, 2003)
      Transparency is a graphical effect used in visualizations to present co-located graphical glyphs. Accomplishing a visually convincing transparency effect requires complex calculations of light absorption and refraction in ...

    • Interactive Dynamic Environments Using Image-Based Modeling and Rendering 

      Davis, Timothy A.; Ficklin, Stephen P. (Eurographics Association, 2003)
      This paper presents a method for rendering a dynamic virtual environment using IBMR at interactive rates. Most IBMR methods are designed for use with static scenes and are awkward when extended temporally due to excessive ...

    • Interactive Dynamic Environments Using Image-Based Modeling and Rendering (393.4 kB) Timothy A. Davis, Stephen P. Ficklin An approach to construct augmented CAD models using acquired digital images 

      Bianconi, Francesco; Conti, Paolo (Eurographics Association, 2003)
      An approach for integrating CAD models and information associated with digital images is discussed in this paper. The main objective of the proposed framework is the construction of augmented CAD models using digital images ...

    • An Iterative Stripification Algorithm Based on Dual Graph Operations 

      Porcu, Massimiliano B.; Scateni, Riccardo (Eurographics Association, 2003)
      This paper describes the preliminary results obtained using an iterative method for generating a set of triangle strips from a mesh of triangles. The algorithm uses a simple topological operation on the dual graph of the ...

    • Mobile Augmented Reality for Environmental Management (MARE) 

      Danado, Jose; Dias, Eduardo; Romao, Teresa; Correia, Nuno; Trabuco, Adelaide; Santos, Carlos; Araujo, David; Duarte, Pedro; Rebocho, Rui; Palmeiro, Jose; Serpa, Joao; Costa, Manuel; Camara, Antonio (Eurographics Association, 2003)
      Access to real-time data while in field observations is often a requested issue in environmental management. Additionally, it is easier to see that information spatially distributed where it makes sense, leveraging users ...

    • Morphing Rational B-spline Curves and Surfaces Using Mass Distributions 

      Ju, Tao; Goldman, Ron (Eurographics Association, 2003)
      A rational B-spline curve or surface is a collection of points associated with a mass (weight) distribution. These mass distributions can be used to exert local control over the morph between two rational B-spline curves ...

    • Motion Planning and Visibility Problems using the Polar Diagram 

      Grima, C.I.; Márquez, A.; Ortega, L. (Eurographics Association, 2003)
      Motion planning and visibility problems are some of the most important topics studied in Computer Graphics, Computational Geometry and Robotics. There exits several and important results to these problems. We propose a new ...

    • Multilevel modelling and rendering of architectural scenes 

      Kushal, Akash M.; Chanda, Gaurav; Shrivastava, Kanishka; Gupta, Mohit; Sanyal, Subhajit; Sriram, T. V. N.; Kalra, Prem; Banerjee, Subhashis (Eurographics Association, 2003)
      We present a novel approach for multilevel modelling and rendering of architectural scenes using a small set of photographs. Our approach is based on interactive probing of intuitive measures like lengths, widths and heights ...

    • Occlusion Culling for Image-Based Rendering withWarping 

      Soner, I. Sen; Atalay, Volkan (Eurographics Association, 2003)
      The basic idea of the proposed algorithm is to reduce the number of depth pixels in Layer Depth Images (LDI) by culling the occluded ones before warping. The method combines the octree spatial subdivision concept with LDI ...

    • On the characterization of avatars in Distributed Virtual Worlds 

      Morillo, Pedro; Fernandez, Marcos; Orduna, Juan Manuel (Eurographics Association, 2003)
      Current Distributed Virtual Environment (DVE) systems run simulations based on a server-network architecture, where the population of avatars should be properly assigned to the servers in the DVE. This goal, called ...

    • Parallel Visibility Test and Occlusion Culling in Avango Virtual Environment Framework 

      Klimenko, Stanislav; Nikitina, Lialia; Nikitin, Igor (Eurographics Association, 2003)
      Real-time visibility test is an attractive feature for Virtual Environment (VE) applications where large datasets should be interactively explored. In such scenes most of the objects are usually occluded by other ones, and ...
