  Liu, Xinguo; Sloan, Peter-Pike; Shum, Heung-Yeung; Snyder, John (The Eurographics Association, 2004)

  We introduce a method based on precomputed radiance transfer (PRT) that allows interactive rendering of glossy surfaces and includes shadowing effects from dynamic, "all-frequency" lighting. Specifically, source lighting ...

• A Novel Hemispherical Basis for Accurate and Efficient Rendering 

  Gautron, Pascal; Krivanek, Jaroslav; Pattanaik, Sumanta; Bouatouch, Kadi (The Eurographics Association, 2004)

  This paper presents a new set of hemispherical basis functions dedicated to hemispherical data representation. These functions are derived from associated Legendre polynomials. We demonstrate the usefulness of this basis ...

• Spherical Harmonic Gradients for Mid-Range Illumination 

  Annen, Thomas; Kautz, Jan; Durand, Frédo; Seidel, Hans-Peter (The Eurographics Association, 2004)

  Spherical harmonics are often used for compact description of incident radiance in low-frequency but distant lighting environments. For interaction with nearby emitters, computing the incident radiance at the center of an ...

• Feature-Based Textures 

  Ramanarayanan, G.; Bala, K.; Walter, B. (The Eurographics Association, 2004)

  This paper introduces feature-based textures, a new image representation that combines features and samples for high-quality texture mapping. Features identify boundaries within an image where samples change discontinuously. ...

• Smooth Reconstruction and Compact Representation of Reflectance Functions for Image-based Relighting 

  Masselus, Vincent; Peers, Pieter; Dutré, Philip; Willemsy, Yves D. (The Eurographics Association, 2004)

  In this paper we present a new method to reconstruct reflectance functions for image-based relighting. A reflectance function describes how a pixel in a photograph is observed depending on the incident illumination on the ...

• Progressively-Refined Reflectance Functions from Natural Illumination 

  Matusik, Wojciech; Loper, Matthew; Pfister, Hanspeter (The Eurographics Association, 2004)

  In this paper we present a simple, robust, and efficient algorithm for estimating reflectance fields (i.e., a description of the transport of light through a scene) for a fixed viewpoint using images of the scene under ...

• Combining Higher-Order Wavelets and Discontinuity Meshing: a Compact Representation for Radiosity 

  Holzschuch, N.; Alonso, L. (The Eurographics Association, 2004)

  The radiosity method is used for global illumination simulation in diffuse scenes, or as an intermediate step in other methods. Radiosity computations using Higher-Order wavelets achieve a compact representation of the ...

• Bixels: Picture Samples with Sharp Embedded Boundaries 

  Tumblin, Jack; Choudhury, Prasun (The Eurographics Association, 2004)

  Pixels store a digital image as a grid of point samples that can reconstruct a limited-bandwidth continuous 2-D source image. Although convenient for anti-aliased display, these bandwidth limits irreversibly discard important ...

• A Self-Reconfigurable Camera Array 

  Zhang, Cha; Chen, Tsuhan (The Eurographics Association, 2004)
