      Recent advances in GPU technology have produced a shift in focus for real-time rendering applications, whereby improvements in image quality are sought in addition to raw polygon display performance. Rendering effects such ...

    • Real-time Obscurances with Color Bleeding (the three cubes demo) 

      Méndez, Àlex; Sbert, Mateu; Catà, Jordi (Eurographics Association, 2003)
      Here we present an animation that demonstrates the power of the obscurances technique and how it can be used in a video-game context when moving objects are in the scene. Obscurances is a powerful technique that simulates ...

    • Morphing Rational B-spline Curves and Surfaces Using Mass Distributions 

      Ju, Tao; Goldman, Ron (Eurographics Association, 2003)
      A rational B-spline curve or surface is a collection of points associated with a mass (weight) distribution. These mass distributions can be used to exert local control over the morph between two rational B-spline curves ...

    • Improved Indirect Photon Mapping withWeighted Importance Sampling 

      Szirmay-Kalos, Laszlo; Szecsi, Laszl (Eurographics Association, 2003)
      This paper offers a novel approach to the indirect photon mapping method. The placement of photons acting as virtual light sources is regarded as a cheap sampling scheme, allowing for the reuse of a complete shooting path ...

    • The Virtual Painting Paintbox 

      Sobczyk, D.; Boyer, V.; Bourdin, J-J. (Eurographics Association, 2003)
      We present VPUP8 a new kind of paint boxes. It includes a model for the simulation of physic dynamics involved in the painting process and a human-machine interface to manage the position and the moves of the user. Usually ...

    • A New 3D Spring for Deformable Object Animation 

      Jeong, Il-Kwon; Lee, Inho (Eurographics Association, 2003)
      A new3D spring for deformable object animation is proposed. Currently mass-spring system is most widely used in a deformable object animation as well as cloth animation. In order to perform a realistic cloth animation using ...

    • Advanced Shading Techniques 

      Diepstraten, Joachim (Eurographics Association, 2003)
      Focus of this talk: • Per-pixel point light Blinn-Phong lighting • Per-pixel realistic metal-BRDF • Per-pixel anisotropic lighting • Procedural textures • Different reflection/environment mapping techniques • “Faked“ translucency

    • Image-based Extraction of Material Reflectance Properties of a 3D Rigid Object 

      Erdem, M. Erkut; Erdem, I. Aykut; Atalay, Volkan (Eurographics Association, 2003)
      In this study, we concentrate on the extraction of reflectance properties of a 3D rigid object from its 2D images and the other aim of this work is rendering the object in real-time with photorealistic quality in varying ...

    • A Refereed Server for Educational CG Content 

      Figueiredo, Frederico C.; Eber, Dena E.; Jorge, Joaquim A. (Eurographics Association, 2003)
      Computer graphics has evolved considerably over the past few decades. As computer science, digital arts, and other areas of study that use computer graphics continue to evolve and gain new substance, educators have come ...

    • Parallel Visibility Test and Occlusion Culling in Avango Virtual Environment Framework 

      Klimenko, Stanislav; Nikitina, Lialia; Nikitin, Igor (Eurographics Association, 2003)
      Real-time visibility test is an attractive feature for Virtual Environment (VE) applications where large datasets should be interactively explored. In such scenes most of the objects are usually occluded by other ones, and ...

    • Lip-Synching in Sourdough 

      Davis, Timothy A.; Johnson, Rebecca (Eurographics Association, 2003)
      This animation relates the story of a seemingly sweet doughy spokesman that has now gone sour. Through his crusty demeanor and somewhat greasy antics, our hero discovers that if you try to have your cake and eat it too, ...

    • VR Game Interfaces for Interaction onto 3D Display 

      Choi, Jeong-Dan; Jang, Byung-Tae; Hwang, Chi-Jeong (Eurographics Association, 2003)
      This paper describes the VR game interfaces for interaction onto 3D display. The challenge we are interested in is how to build and use a low cost 3D display that satisfies semi-immersive requirements and how to coordinate ...
