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 ... -
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 ... -
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 ... -
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, ... -
Rainbow: A Rendering-Aware Index for High-Quality Spatial Scatterplots with Result-Size Budgets
(The Eurographics Association, 2022)We study the problem of computing a spatial scatterplot on a large dataset for arbitrary zooming/panning queries. We introduce a general framework called ''Rainbow'' that generates a high-quality scatterplot for a given ... -
Random Accessible Hierarchical Mesh Compression for Interactive Visualization
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper presents a novel algorithm for hierarchical random accessible mesh decompression. Our approach progressively decompresses the requested parts of a mesh without decoding less interesting parts. Previous approaches ... -
The Random Camera, the Coded Aperture Camera, and Other Cameras
(The Eurographics Association, 2007)I ll describe two cameras and a comparison of many cameras. In the random camera, we use a lens which creates a pseudo-random relationship between incoming light rays and resulting sensor locations. We studied various ... -
Random Discrete Colour Sampling
(The Eurographics Association, 2012)Apparently-random distributions of colours in a discrete setting have been used by many artists and craftsmen in the past century. Manual colourisation is a tedious and difficult process. Automatic colourisation, on the ... -
Random-Forest-Based Initializer for Real-time Optimization-based 3D Motion Tracking Problems
(The Eurographics Association, 2019)Many motion tracking systems require solving inverse problem to compute the tracking result from original sensor measurements, such as images from cameras and signals from receivers. For real-time motion tracking, such ... -
Randomized Selection on the GPU
(ACM, 2011)We implement here a fast and memory-sparing probabilistic top k selection algorithm on the GPU. The algorithm proceeds via an iterative probabilistic guess-and-check process on pivots for a three-way partition. When the ... -
Randomized Sub-Volume Partitioning for Part-Based 3D Model Retrieval
(The Eurographics Association, 2015)Given a query that specifies partial shape, a Part-based 3D Model Retrieval (P3DMR) system would retrieve 3D models whose part(s) matches the query. Computationally, this is quite challenging; the query must be compared ... -
Range Scans based 3D Shape Retrieval
(The Eurographics Association, 2015)The objective of the SHREC'15 Range Scans based 3D Shape Retrieval track is to evaluate algorithms that match range scans of real objects to complete 3D mesh models in a target dataset. The task is to retrieve a rank list ... -
Rapid Acquisition of Specular and Diffuse Normal Maps from Polarized Spherical Gradient Illumination
(The Eurographics Association, 2007)We estimate surface normal maps of an object from either its diffuse or specular reflectance using four spherical gradient illumination patterns. In contrast to traditional photometric stereo, the spherical patterns allow ... -
