    • Topological Construction and Visualization of Higher Order 3D Vector Fields 

      Weinkauf, Tino; Theisel, Holger; Hege, Hans-Christian; Seidel, Hans-Peter (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present the first algorithm for constructing 3D vector fields based on their topological skeleton. The skeleton itself is modeled by interactively moving a number of control polygons. Then a piecewise linear vector field ...

    • Virtual Drypoint by a Model-driven Strategy 

      Tasaki, Daisuke; Mizuno, Shinji; Okada, Minoru (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      In this paper we propose a method to synthesize a virtual copperplate print image based on physical model as a non-photorealistic rendering in Computer Graphics. In particular we pick out the drypoint from many existing ...

    • VOTS: VOlume doTS as a Point-Based Representation of Volumetric Data 

      Grimm, Soeren; Bruckner, Stefan; Kanitsar, Armin; Groeller, Eduard (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      We present Volume dots (Vots), a new primitive for volumetric data modelling, processing, and rendering. Vots are a point-based representation of volumetric data. An individual Vot is specified by the coefficients of a ...

    • Way-Finder: guided tours through complex walkthrough models 

      Andujar, C.; Vazquez, P.; Fairen, M. (The Eurographics Association and Blackwell Publishing, Inc, 2004)
      The exploration of complex walkthrough models is often a difficult task due to the presence of densely occluded regions which pose a serious challenge to online navigation. In this paper we address the problem of algorithmic ...
