    • An Architecture For Interactive Tetrahedral Volume Rendering 

      King, Davis; Wittenbrink, Craig M.; Wolters, Hans J. (The Eurographics Association, 2001)
      We present a new architecture for interactive unstructured volume rendering. Our system moves all the computations necessary for order-independent transparency and volume scan conversion from the CPU to the graphics hardware, ...

    • Volume Graphics Modeling of Ice Thawing 

      Fujishiro, Issei; Aoki, Etsuko (The Eurographics Association, 2001)
      Image synthesis of natural phenomena is one of the fundamental research areas in volume graphics. Since the pursuit of photoreality requires physically-based computation at the cost of interactivity, much more attention ...

    • A Study of Transfer Function Generation for Time-Varying Volume Data 

      Jankun-Kelly, T.J.; Ma, Kwan-Liu (The Eurographics Association, 2001)
      The proper usage and creation of transfer functions for time-varying data sets is an often ignored problem in volume visualization. Although methods and guidelines exist for time-invariant data, little formal study for the ...

    • A Survey of Methods for Volumetric Scene Reconstruction from Photographs 

      Slabaugh, Greg; Culbertson, Bruce; Malzbender, Tom; Schafer, Ron (The Eurographics Association, 2001)
      Scene reconstruction, the task of generating a 3D model of a scene given multiple 2D photographs taken of the scene, is an old and difficult problem in computer vision. Since its introduction, scene reconstruction has found ...

    • Splatting With Shadows 

      Nulkar, Manjushree; Mueller, Klaus (The Eurographics Association, 2001)
      In this paper we describe an efficient approach to add shadows to volumetric scenes. The light emitted by the lightsource is properly attenuated by the intervening volumetric structures before it is reflected towards the ...

    • Data Level Comparison of Surface Classification and Gradient Filters 

      Kim, Kwansik; Wittenbrink, Craig M.; Pang, Alex (The Eurographics Association, 2001)
      Surface classification and shading of three dimensional scalar data sets are important enhancements for direct volume rendering (DVR). However, unlike conventional surface rendering, DVR algorithms do not have explicit ...

    • Refraction in Discrete Ray Tracing 

      Rodgman, David; Chen, Min (The Eurographics Association, 2001)
      Refraction is an important graphics feature for synthesizing photorealistic images. This paper presents a study on refraction rendering in volume graphics using discrete ray tracing. We describe four basic approaches for ...
