    • PC-based Real-time Texture Painting on Real World Objects 

      Iwakiri, Yuya; Kaneko, Toyohisa (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The problem of texture mapping on real world objects has attracted attention11,8 recently. A work by Lensch et al.9 addressed the problem of locating a camera position in the celestial sphere and then mapping the acquired ...

    • Rendering: Input and Output 

      Rushmeier, H. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Rendering is the process of creating an image from numerical input data. In the past few years our ideas about methods for acquiring the input data and the form of the output have expanded. The availability of inexpensive ...

    • Rendering Pearlescent Appearance Based On Paint-Composition Modelling 

      Ershov, Sergey; Kolchin, Konstantin; Myszkowski, Karol (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across ...

    • Flexible Image-Based Photometric Reconstruction using Virtual Light Sources 

      Gibson, Simon; Howard, Toby; Hubbold, Roger (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Photometric reconstruction is the process of estimating the illumination and surface reflectance properties of an environment, given a geometric model of the scene and a set of photographs of its surfaces. For mixed-reality ...

    • A Dynamic Motion Control Technique for Human-like Articulated Figures 

      Oshita, Masaki; Makinouchi, Akifumi (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      This paper presents a dynamic motion control technique for human-like articulated figures in a physically based character animation system. This method controls a figure such that the figure tracks input motion specified ...

    • Why Games Will Be the Preeminent Art Form of the 21stCentury 

      Hecker, Chris (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Computer games share many artistic and technical characteristics with films of the early 1900s. Games' artistic evolution is hampered by the lack of artistic respect from society at large, and the lack of technical standards ...

    • Interactive Rendering with Coherent Ray Tracing 

      Wald, Ingo; Slusallek, Philipp; Benthin, Carsten; Wagner, Markus (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      For almost two decades researchers have argued that ray tracing will eventually become faster than the rasterization technique that completely dominates todays graphics hardware. However, this has not happened yet. Ray ...

    • Automatic Lighting Design using a Perceptual Quality Metric 

      Shacked, Ram; Lischinski, Dani (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Lighting has a crucial impact on the appearance of 3D objects and on the ability of an image to communicate information about a 3D scene to a human observer. This paper presents a new automatic lighting design approach for ...

    • Global Illumination as a Combination of Continuous Random Walk and Finite-Element Based Iteration 

      Szirmay-Kalos, Laszlo; Csonka, Ferenc; Antal, Gyorgy (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The paper introduces a global illumination method that combines continuous and finite-element approaches, pre-serving the speed of finite-element based iteration and the accuracy of continuous random walks. The basic idea ...

    • Incremental Updates for Rapid Glossy Global Illumination 

      Granier, Xavier; Drettakis, George (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We present an integrated global illumination algorithm including non-diffuse light transport which can handle complex scenes and enables rapid incremental updates. We build on a unified algorithm which uses hierarchical ...

    • Perceptually Guided Corrective Splatting 

      Haber, Jorg; Myszkowski, Karol; Yamauchi, Hitoshi; Seidel, Hans-Peter (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      One of the basic difficulties with interactive walkthroughs is the high quality rendering of object surfaces with non-diffuse light scattering characteristics. Since full ray tracing at interactive rates is usually impossible, ...

    • A Camera Engine for Computer Games: Managing the Trade-Off Between Constraint Satisfaction and Frame Coherence 

      Halper, Nicolas; Helbing, Ralf; Strothotte, Thomas (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      Many computer games treat the user in the "1st person" and bind the camera to his or her view. More sophistication in a game can be achieved by enabling the camera to leave the users' viewpoint. This, however, requires new ...

    • Walk-Through Illustrations: Frame-Coherent Pen-and-Ink Style in a Game Engine 

      Freudenberg, Bert; Masuch, Maic; Strothotte, Thomas (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In this paper we show how a game engine designed to generate photorealistic images can be extended to produce non-photorealistic and hybrid renditions. We introduce new hardware-based methods to accomplish pen-and-ink ...

    • An Adaptive Method for Indirect Illumination Using Light Vectors 

      Serpaggi, Xavier; Peroche, Bernard (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      In computer graphics, several phenomema need to be taken into account when it comes to the field of photo-realism. One of the most relevant is obviously the notion of global, and more precisely indirect, illumination. In ...

    • Instant Visibility 

      Wonka, Peter; Wimmer, Michael; Sillion, Francois X. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      We present an online occlusion culling system which computes visibility in parallel to the rendering pipeline. We show how to use point visibility algorithms to quickly calculate a tight potentially visible set (PVS) which ...

    • Linear Interval Estimations for Parametric Objects Theory and Application 

      Buehler, Katja (Blackwell Publishers Ltd and the Eurographics Association, 2001)
      The new concept of parametrized bounding volumes for parametric objects is proposed to replace the common compact bounding volumes like axis aligned bounding boxes and parallelepipeds. Linear Interval Estimations (LIEs) ...

    • Tensor Topology Tracking: A Visualization Method for Time-Dependent 2D Symmetric Tensor Fields 

      Tricoche, X.; Scheuermann, G.; Hagen, H. (Blackwell Publishers Ltd and the Eurographics Association, 2001)
