Strategies for More Energy Efficient Volume Analysis and Direct Volume Rendering Descriptor Computation
(The Eurographics Association, 2023)A study of energy use (in an x86-class environment) for computation of descriptors used in analysis and in one common scientific visualisation strategy, direct volume rendering (DVR), of volumetric data is presented. Focus ... -
A Stratification Matrix Viewer for Analysis of Neural Network Data
(The Eurographics Association, 2022)The analysis of brain networks is central to neurobiological research. In this context the following tasks often arise: (1) understand the cellular composition of a reconstructed neural tissue volume to determine the nodes ... -
Stratified Markov Chain Monte Carlo Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Markov chain Monte Carlo (MCMC) sampling is a powerful approach to generate samples from an arbitrary distribution. The application to light transport simulation allows us to efficiently handle complex light transport such ... -
Stratified Point Sampling of 3D Models
(The Eurographics Association, 2004)Point sampling is an important intermediate step for a variety of computer graphics applications, and specialized sampling strategies have been developed to satisfy the requirements of each problem. In this article, we ... -
Stratified Sampling for Stochastic Transparency
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The traditional method of rendering semi-transparent surfaces using alpha blending requires sorting the surfaces in depth order. There are several techniques for order-independent transparency, but most require either ... -
Stratified Sampling of Projected Spherical Caps
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a method for uniformly sampling points inside the projection of a spherical cap onto a plane through the sphere's center. To achieve this, we devise two novel area-preserving mappings from the unit square to ... -
StratomeX: Visual Analysis of Large-Scale Heterogeneous Genomics Data for Cancer Subtype Characterization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)Identification and characterization of cancer subtypes are important areas of research that are based on the integrated analysis of multiple heterogeneous genomics datasets. Since there are no tools supporting this process, ... -
Stream Compaction for Deferred Shading
(The Eurographics Association, 2009)The GPU leverages SIMD efficiency when shading because it rasterizes a triangle at a time, running the same shader on all of its fragments. Ray tracing sacrifices this shader coherence, and the result is that SIMD units ... -
Stream Line–Based Pattern Search in Flows
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)We propose a method that allows users to define flow features in form of patterns represented as sparse sets of stream line segments. Our approach finds similar occurrences in the same or other time steps. Related approaches ... -
A Stream Ribbon Seeding Strategy
(The Eurographics Association, 2017)Streamline seeding algorithms have a long and rich history dating back over two decades. And in recent years algorithms for stream surface placement have been developed. However, stream ribbons have been generally overlooked. ... -
Stream Surface Generation for Fluid Flow Solutions on Curvilinear Grids
(The Eurographics Association, 2001)A stream surface in a steady-state three-dimensional fluid flow vector field is a surface across which there is no flow. Stream surfaces can be useful for visualization because the amount of data presented in one visualization ... -
Stream Surface Parametrization by Flow-Orthogonal Front Lines
(The Eurographics Association and Blackwell Publishing Ltd., 2012)The generation of discrete stream surfaces is an important and challenging task in scientific visualization, which can be considered a particular instance of geometric modeling. The quality of numerically integrated stream ... -
Streamed Ray Tracing of Single Rays on the Cell Processor
(The Eurographics Association, 2010)In this paper we present an approach to efficiently trace single rays on the Cell Processor, instead of using ray packets. To benefit from the performance of this processor, a data structure is chosen which allows traversal ... -
A Streaming Algorithm for Surface Reconstruction
(The Eurographics Association, 2007)We present a streaming algorithm for reconstructing closed surfaces from large non-uniform point sets based on a geometric convection technique. Assuming that the sample points are organized into slices stacked along one ... -
Streaming and Data Enrichment
(The Eurographics Association, 2007)Data is being created at a continuously increasing rate. Scientists are drowning in their data . So much so they cannot visualize the data to see the big picture. This work-in-progress paper describes a data capture and ... -
Streaming Approach to In Situ Selection of Key Time Steps for Time-Varying Volume Data
(The Eurographics Association and John Wiley & Sons Ltd., 2022)Key time steps selection, i.e., selecting a subset of most representative time steps, is essential for effective and efficient scientific visualization of large time-varying volume data. In particular, as computer simulations ... -
Streaming Compression of Triangle Meshes
(The Eurographics Association, 2005)Current mesh compression schemes encode triangles and vertices in an order derived from systematically traversing the connectivity graph. These schemes struggle with gigabyte-sized mesh input where the construction and the ... -
A Streaming Framework for Seamless Detailed Photo Blending on Massive Point Clouds
(The Eurographics Association, 2011)We present an efficient scalable streaming technique for mapping highly detailed color information on extremely dense point clouds. Our method does not require meshing or extensive processing of the input model, works on ... -
Streaming G-Buffer Compression for Multi-Sample Anti-Aliasing
(The Eurographics Association, 2014)We present a novel lossy compression algorithm for G-buffers that enables deferred shading applications with high visibility sampling rates. Our streaming compression method operates in a single geometry rendering pass ... -
