R-Buffer: A Pointerless A-Buffer Hardware Architecture
(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-CNN based PolygonalWedge Detection Learned from Annotated 3D Renderings and Mapped Photographs of Open Data Cuneiform Tablets
(The Eurographics Association, 2023)Motivated by the demands of Digital Assyriology and the challenges of detecting cuneiform signs, we propose a new approach using R-CNN architecture to classify and localize wedges. We utilize the 3D models of 1977 cuneiform ... -
R-V Dynamics Illusion: Psychophysical Phenomenon Caused by the Difference between Dynamics of Real Object and Virtual Object
(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
(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 ... -
RadEx: Integrated Visual Exploration of Multiparametric Studies for Radiomic Tumor Profiling
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Better understanding of the complex processes driving tumor growth and metastases is critical for developing targeted treatment strategies in cancer. Radiomics extracts large amounts of features from medical images which ... -
Radial Symmetry Detection and Shape Characterization with the Multiscale Area Projection Transform
(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
(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 ... -
Radiance-Based Blender Add-On for Physically Accurate Rendering of Cultural Heritage
(The Eurographics Association, 2023)Despite the Cultural Heritage and Computer Graphics communities are increasingly joining forces to strengthen their collaboration, the study of how light interacts with monuments (e.g. weathering the surfaces or affecting ... -
A Radicalized Phenomenological Transformation Of Greek/Unani Humoral Theory Into A Virtual Reality Based Game Engine
(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
(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
(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
(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
(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
(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
(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
(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
(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, ... -
Rain Wiper: An Incremental RandomlyWired Network for Single Image Deraining
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Single image rain removal is a challenging ill-posed problem due to various shapes and densities of rain streaks. We present a novel incremental randomly wired network (IRWN) for single image deraining. Different from ... -
Rainbow: A Rendering-Aware Index for High-Quality Spatial Scatterplots with Result-Size Budgets
