    • Tone Reproduction for Interactive Walkthroughs 

      Scheel, A.; Stamminger, M.; Seidel, H.-P. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      When a rendering algorithm has created a pixel array of radiance values the task of producing an image is not yet completed. In fact, to visualize the result the radiance values still have to be mapped to luminances, which ...

    • Web-Based Remote Renderingwith IBRAC (Image-Based Rendering Acceleration and Compression) 

      Yoon, I.; Neumann, U. (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      Recent advances in Internet and computer graphics stimulate intensive use and development of 3D graphics on the World Wide Web. To increase efficiency of systems using 3D graphics on the web, the presented method utilizes ...

    • Integration of Multidimensional Interaction Devices in Real-Time Computer Graphics Applications 

      Frohlich, Torsten; Roth, Marcus (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      Modern CAD/CAM and Virtual Reality applications cannot be imagined without the new class of interaction devices allowing the user direct interaction with computer generated scenes. Integrating such devices into existing ...

    • Modeling the Motion of Dense Smoke in the Wind Field 

      Rudolf, Marcin J.; Raczkowski, Jacek (Blackwell Publishers Ltd and the Eurographics Association, 2000)
      This paper presents a volumetric animation technique for modeling the turbulent motion of very dense and turbulent smoke such as one coming from a steam engine. A new method of the wind field generation is proposed. Gas ...

    • An Adaptive Spectral Rendering with a Perceptual Control
