Improving the Sensitivity of Statistical Testing for Clusterability with Mirrored-Density Plots
(The Eurographics Association, 2020)For many applications, it is crucial to decide if a dataset possesses cluster structures. This property is called clusterability and is usually investigated with the usage of statistical testing. Here, it is proposed to ... -
Improving Topological Segmentation of Three-dimensional Vector Fields
(The Eurographics Association, 2003)We present three enhancements to accelerate the extraction of separatrices of three-dimensional vector fields, using intelligently selected "sample" streamlines. These enhancements reduce the number of needed sample ... -
Improving View Independent Rendering for Multiview Effects
(The Eurographics Association, 2022)This paper describes improvements to view independent rendering (VIR) that make it much more useful for multiview effects. Improved VIR's (iVIR's) soft shadows are nearly identical in quality to VIR's and produced with ... -
The Impulse Graph: A New Dynamic Structure For Global Collisions
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In interactive virtual environments and dynamic simulations, collisions between complex objects and articulated bodies may occur simultaneously at multiple points or regions of interference. Many solutions to the collision ... -
The Impulse Particle-In-Cell Method
(The Eurographics Association and John Wiley & Sons Ltd., 2024)An ongoing challenge in fluid animation is the faithful preservation of vortical details, which impacts the visual depiction of flows. We propose the Impulse Particle-In-Cell (IPIC) method, a novel extension of the popular ... -
Impulse Responses for Precomputing Light from Volumetric Media
(The Eurographics Association, 2019)Modern interactive rendering can rely heavily on precomputed static lighting on surfaces and in volumes. Scattering from volumetric media can be similarly treated using precomputation, but transport from volumes onto ... -
In at the Deep End: An Activity-Led Introduction to Creative Computing with Interactive Computer Graphics
(The Eurographics Association, 2011)Misconceptions about the nature of the computing discipline(s) pose a serious problem to faculties that offer computing degrees, as students enrolling on their programmes come to realise that their expectations are not met ... -
In at the Deep End: An Activity-Led Introduction to First Year Creative Computing
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Misconceptions about the nature of the computing disciplines pose a serious problem to university faculties that offer computing degrees, as students enrolling on their programmes may come to realise that their expectations ... -

In Praise of an Alternative BRDF Parametrization
(The Eurographics Association, 2015)In this paper, we extend the work of Neumann et al. [NNSK99] and Stark et al. [SAS05] to a pair of 4D BRDF parameterizations with explicit changes of variables. We detail their mathematical properties and relationships to ... -
In Situ and Post Processing Workflows for Asteroid Ablation Studies
(The Eurographics Association, 2017)Simulation scientists need to make decisions about what and how much output to produce. They must balance their ability to efficiently ingest the analysis with their ability to get more analysis. We study this balance as ... -
In Situ Methods, Infrastructures, and Applications on High Performance Computing Platforms
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The considerable interest in the high performance computing (HPC) community regarding analyzing and visualization data without first writing to disk, i.e., in situ processing, is due to several factors. First is an I/O ... -
In Situ Pathtube Visualization with Explorable Images
(The Eurographics Association, 2013)In situ processing is considered to be the most plausible data analysis and visualization solution for extreme-scale simulations. Explorable images were introduced as an in situ visualization method to enable interactive ... -
In the Eye of the Beholder - Perception of Indeterminate Art
(The Eurographics Association, 2007)How do we interpret an object - a scene - a painting? Perception research and art illuminate from different angles how the vast amount of information in our visually perceived environment is processed by the viewer to form ... -
In-Situ 3D Sketching Using a Video Camera as an Interaction and Tracking Device
(The Eurographics Association, 2010)In this paper, we present a novel method for in-situ 3D sketching of polyhedral scenes. A video camera is used as both an interaction and a tracking device, which makes the system particularly suitable for handheld devices ... -
In-situ Sampling of a Large-Scale Particle Simulation for Interactive Visualization and Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We describe a simulation-time random sampling of a large-scale particle simulation, the RoadRunner Universe MC3 cosmological simulation, for interactive post-analysis and visualization. Simulation data generation rates ... -
In-the-wild Material Appearance Editing using Perceptual Attributes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Intuitively editing the appearance of materials from a single image is a challenging task given the complexity of the interactions between light and matter, and the ambivalence of human perception. This problem has been ... -
IN2CO - A Visualization Framework for Intuitive Collaboration
(The Eurographics Association, 2016)Today, the need for interaction and visualization techniques to fulfill user requirements for collaborative work is ever increasing. Current approaches do not suffice since they do not consider the simultaneous work of ... -
IN2TUNNEL - Terapia de Exposição para Fobia de Atravessar Túneis
(The Eurographics Association, 2020)O uso da Realidade Virtual na Terapia de Exposição (RVTE) permite que um paciente seja exposto à situação temida, sem recorrer a uma exposição real o que é particularmente vantajoso quando a reprodução da situação real é ...
