• Pareto-Based Perceptual Metric for Imperceptible Simplification on Mobile Displays 

  Wu, Fan; Agu, Emmanuel; Lindsay, Clifford (The Eurographics Association, 2007)

  Graphics on mobile devices has become popular because untethered computing is convenient and increases pro- ductivity. Mobile displays come in different resolutions that affect the scene Level-of-Detail (LoD) that users ...

• Fast Hierarchical 3D Distance Transforms on the GPU 

  Cuntz, Nicolas; Kolb, Andreas (The Eurographics Association, 2007)

  This paper describes a fast approximate approach for the GPU-based computation of 3D Euclidean distance transforms (DT), i.e. distance fields with associated vector information to the closest object point. Our hierarchical ...

• Real-Time 3D Lettering with a 2D Font Engine 

  Heise, Sebastian; Loviscach, Jörn (The Eurographics Association, 2007)

  Standard texturing shows a number of problems with 3D objects such as road signs, labels, or books. If letters are displayed at too large a scale, textures show blurred instead of hard edges; if letters are displayed at ...

• Liquid Diffusion Model that Accounts for a Variety of Dyeing Parameters 

  Yuki, Morimoto; Tanaka, Masayuki; Tsuruno, Reiji; Tomimatsu, Kiyoshi (The Eurographics Association, 2007)

  This paper describes a method for simulating and visualizing dyeing based on weave patterns and the physical parameters of the threads and the dye. We apply Fick s second law with a variable diffusion coefficient, which ...

• Painterly Effects Rendering with Focus Based Level of Detail 

  Levente, Kovács; Tamás, Szirányi (The Eurographics Association, 2007)

  We present a novel method for automatically creating scalable and portable 2D non-photorealistically rendered (NPR) images with painterly effects, with level of detail control. The novelty of the approach lies both in using ...

• Adaptive Abstraction of 3D scenes in Real-Time 

  Redmond, Niall; Dingliana, John (The Eurographics Association, 2007)

  We present an approach for creating abstracted renderings of 3D scenes in real-time. We create painterly renderings with edge detail using varying levels of abstraction dependent on regions of interest within a scene. Image ...

• Simultaneous Visualization of Preoperative Planning Models and Intraoperative 2D Ultrasound for Liver Surgery 

  Hansen, Christian; Köhn, Alexander; Zidowitz, Stephan; Peitgen, Heinz-Otto; Ritter, Felix (The Eurographics Association, 2007)

  This paper introduces new techniques for simultaneous visualization of preoperative planning models and intraoperative 2D ultrasound for open liver surgery. The driving motivation for our work is to improve the visual ...

• Fast Hierarchical Methods to Detect Collisions between Deformable Objects: A Comparison 

  Madera, Francisco; Day, A. M.; Laycock, S. D. (The Eurographics Association, 2007)

  The time complexity of a collision detection algorithm can be reduced to logarithmic in the number of tests performed when the objects are decomposed into a Bounding Volume (BV) tree hierarchy. It is well known that the ...

• Object-Oriented Shader Design 

  Kuck, Roland (The Eurographics Association, 2007)

  We present an extremely lightweight object-oriented framework for writing shaders. It provides a way to invoke methods of objects from the shading language and to use references of objects as normal variables. Classes are ...
