    • R-Buffer: A Pointerless A-Buffer Hardware Architecture 

      Wittenbrink, Craig M. (The Eurographics Association, 2001)
      We present a graphics hardware architecture that implements Carpenter's A-buffer. The A-buffer is a software renderer that uses pointer based linked lists. Our pointerless approach computes order independent transparency ...
    • R-V Dynamics Illusion: Psychophysical Phenomenon Caused by the Difference between Dynamics of Real Object and Virtual Object 

      Kataoka, Yuta; Hashiguchi, Satoshi; Shibata, Fumihisa; Kimura, Asako (The Eurographics Association, 2015)
      In Mixed-Reality (MR) space, it appeared that the sense of weight can be affected by a MR visual stimulation with a movable portion. We named this psychophysical influence caused by the difference between dynamics of the ...
    • The RACE II Engine for Real-Time Volume Rendering 

      Ray, Harvey; Silver, Deborah (The Eurographics Association, 2000)
      In this paper, we present the RACE II Engine, which uses a hybrid volume rendering methodology that combines algorithmic and hardware acceleration to maximize ray casting performance relative the total amount of volume ...
    • Radial Symmetry Detection and Shape Characterization with the Multiscale Area Projection Transform 

      Giachetti, Andrea; Lovato, Christian (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      We present a novel method to characterize 3D surfaces through the computation of a function called (multiscale) area projection transform, measuring the likelihood of points in the 3D space to be center of radial symmetry ...
    • Radiance Cache Splatting: A GPU-Friendly Global Illumination Algorithm 

      Gautron, Pascal; Krivánek, Jaroslav; Bouatouch, Kadi; Pattanaik, Sumanta (The Eurographics Association, 2005)
      Fast global illumination computation is a challenge in several fields such as lighting simulation and computergenerated visual effects for movies. To this end, the irradiance caching algorithm is commonly used since it ...
    • A Radicalized Phenomenological Transformation Of Greek/Unani Humoral Theory Into A Virtual Reality Based Game Engine 

      Khan, Muqeem (IEEE, 2015)
      This research primarily focusing on the continuity of production, survival and access related to indigenous methodologies through the use of virtual reality, serious gaming technologies and affordances. Specifically, the ...
    • Radiometric Characterization of Spectral Imaging for Textual Pigment Identification 

      Kim, Min H.; Rushmeier, Holly (The Eurographics Association, 2011)
      Digital imaging of cultural heritage artifacts has become a standard practice. Typically, standard commercial cameras, often commodity rather than scientific grade cameras, are used for this purpose. Commercial cameras are ...
    • Radiometric Transfer: Example-based Radiometric Linearization of Photographs 

      Li, Han; Peers, Pieter (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We present an example-based approach for radiometrically linearizing photographs that takes as input a radiometrically linear exemplar image and a target regular uncalibrated image of the same scene, possibly from a different ...
    • Radiosity for dynamic scenes in flatland with the visibility complex 

      ORTI, Rachel; RIVIERE, Stephane; DURAND, Fredo; PUECH, Claude (Blackwell Science Ltd and the Eurographics Association, 1996)
      The radiosity method is particularly suitable for global illumination calculations in static environments. Nonetheless, recent applications of image synthesis such as architectural simulation or lighting design require the ...
    • Radiosity for Furry Surfaces 

      Chen, Hong; Wu, En-Hua (Eurographics Association, 1991)
      Though radiosity method is an advanced rendering technique of global illumination, it is still not sufficiently to cope with many natural phenonmena such as furry surfaces. The rendering of furry surfaces has been a long ...
    • Radiosity for Large Vegetation Scenes 

      Mastal, Helmut; Tobler, Robert F.; Purgathofer, Werner (Eurographics Association, 1999)
      Calculating radiosity solutions for large scenes containing multiple plants is all but impossible using the radiosity method in its original form. With the introduction of sophisticated hierarchical and clustering algorithms ...
    • Radiosity in Flatland 

      Heckhert, Paul S. (Blackwell Science Ltd and the Eurographics Association, 1992)
      The radiosity method for the simulation of interreflection of light between diffuse surfaces is such a common image synthesis technique that its derivation is worthy of study. We here examine the radiosity method in a two ...
    • Radiosity with Well Distributed Ray Sets 

      Neumann, Laszlo; Neumann, Attila; Bekaert, Philippe (Blackwell Publishers Ltd and the Eurographics Association, 1997)
      In this paper we present a new radiosity algorithm, based on the notion of a well distributed ray set (WDRS). A WDRS is a set of rays, connecting mutually visible points and patches, that forms an approximate representation ...
    • Rail-Track Viewer - An Image-Based Virtual Walkthrough System 

      Yang, Lining; Crawfis, Roger (The Eurographics Association, 2002)
      Complex renderings of synthetic scenes or virtual environments, once deemed impossible for consumer rendering, are becoming available as tools for young artists. These renderings, due to their highquality image synthesis, ...
    • RameshCleaner: Conservative Fixing of Triangular Meshes 

      Centin, Marco; Signoroni, Alberto (The Eurographics Association, 2015)
      In this work, after a careful examination of the most common errors and flaws which typically occur in meshes produced by 3D scanning processes, we propose a set of fixing tools which solve effectively several important ...
    • Ramses: a Visual Steganographic System 

      Battiato, S.; Blasi, G. Di; Gallo, G.; Patti, S. (The Eurographics Association, 2007)
      Steganography is the art of "secret communication". Its goal is to transmit a message (information) hidden inside another visible message. The typical visible message used in many steganographic systems is a digital image ...
