CompaRing: Reducing Costs of Visual Comparison
(The Eurographics Association, 2016)Comparison is a frequent task when analyzing data. In visualization, comparison tasks are naturally carried out based on a visual representation of the data. Visual comparison allows us to gain insight where plain computations ... -
Comparison and Evaluation of Viewpoint Quality Estimation Algorithms for Immersive Virtual Environments
(The Eurographics Association, 2015)The knowledge of which places in a virtual environment are interesting or informative can be used to improve user interfaces and to create virtual tours. Viewpoint Quality Estimation algorithms approximate this information ... -
Comparison and Integration of Erosion Evaluation Methods for Rheumatic Degenerative Diseases
(The Eurographics Association, 2020)Monitoring the development of degenerative rheumatic diseases is at the core of an efficient medical evaluation of the patient. Acquiring information on the pathology progression, indeed, helps to personalize the therapy ... -
Comparison between two Three-Dimensional Edge Operators applied in a 3D Navigation Approach
(Eurographics Association, 1998)This paper will compare two 3D surface detection and normal estimation operators applied on a rough voxel database. These approaches can be applied as virtual endoscopy for the exploriation of 3D medical image volumes. The ... -
Comparison of Audio and Visual Cues to Support Remote Guidance in Immersive Environments
(The Eurographics Association, 2020)Collaborative virtual environments provide the ability for collocated and remote participants to communicate and share information with each other. For example, immersive technologies can be used to facilitate collaborative ... -
Comparison of Different Types of Visemes using a Constraint-based Coarticulation Model
(The Eurographics Association, 2010)A common approach to producing visual speech is to interpolate the parameters describing a sequence of mouth shapes, known as visemes, where visemes are the visual counterpart of phonemes. A single viseme typically represents ... -
A Comparison of Digital Modelling Techniques Analyzing a Section of Qhapaq Ñan
(IEEE, 2015)Total Station has been one of the most common acquisition devices for achieving maps through topographic survey. Nowadays, Terrestrial Laser Scanner (TLS) and Photogrammetry are commonly used to generate accurate meshes. ... -
A Comparison of Error Indicators for Multilevel Visualization on Nested Grids
(Springer and The Eurographics Association, 1999)Multiresolution visualization methods have recently become an indispensable ingredient of real time interactive post processing. Here local error indicators serve as criteria where to refine the data representation on the ... -
Comparison of Four Subjective Methods for Image Quality Assessment
(The Eurographics Association and Blackwell Publishing Ltd., 2012)To provide a convincing proof that a new method is better than the state of the art, computer graphics projects are often accompanied by user studies, in which a group of observers rank or rate results of several algorithms. ... -
A Comparison of GPU Tessellation Strategies for Multisided Patches
(The Eurographics Association, 2018)We propose an augmentation of the traditional tessellation pipeline with several different strategies that efficiently render multisided patches using generalised barycentric coordinates. The strategies involve different ... -
Comparison of GPU-based Methods for Handling Point Cloud Occlusion
(The Eurographics Association, 2021)Three-dimensional point clouds have conventionally been used along with several sources of information. This fusion can be performed by projecting the point cloud into the image plane and retrieving additional data for ... -
A comparison of linear consistent correction methods for first-order SPH derivatives
(ACM Association for Computing Machinery, 2023)Awell-known issue with the widely used Smoothed Particle Hydrodynamics (SPH) method is the neighborhood deficiency. Near the surface, the SPH interpolant fails to accurately capture the underlying fields due to a lack of ... -
A Comparison of Methods for Generating Poisson Disk Distributions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Poisson disk distributions have many applications in the field of computer graphics. Besides sampling, Poisson disk distributions are used in object distribution, non-photorealistic rendering and procedural texturing. Over ... -
Comparison of Mixed Linear Complementarity Problem Solvers for Multibody Simulations with Contact
(The Eurographics Association, 2018)The trade-off between accuracy and computational performance is one of the central conflicts in real-time multibody simulations, much of which can be attributed to the method used to solve the constrained multibody equations. ... -
Comparison of Modern Omnidirectional Precise Shadowing Techniques Versus Ray Tracing
(© 2022 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2022)This paper presents an in depth comparison of state‐of‐the‐art precise shadowing techniques for an omnidirectional point light. We chose several types of modern shadowing algorithms, starting from stencil shadow volumes, ... -
Comparison of Morphological Pyramids for Multiresolution MIP Volume Rendering
(The Eurographics Association, 2002)We recently proposed a multiresolution representation for maximum intensity projection (MIP) volume rendering based on morphological adjunction pyramids which allow progressive refinement and have the property of perfect ... -
Comparison of Multiple Weighted Hierarchies: Visual Analytics for Microbe Community Profiling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We propose visual analytics techniques to support concurrent comparison of hundreds of cumulatively weighted instances of a single hierarchy. This includes a node-link representation of the hierarchy where nodes depict the ... -
