3D Modeling in a Web Browser to Formulate Content-Based 3D Queries
(The Eurographics Association, 2009)We present a framework for formulating domain-dependent 3D search queries suitable for content-based 3D search over the web. Users are typically not willing to spend much time to create a 3D query object. They expect to ... -
Collaborative High-fidelity Rendering over Peer-to-peer Networks
(The Eurographics Association, 2014)Due to the computational expense of high-fidelity graphics, parallel and distributed systems have frequently been employed to achieve faster rendering times. The form of distributed computing used, with a few exceptions ... -
Dynamic Scheduling for Progressive Large-Scale Visualization
(The Eurographics Association, 2015)The ever-increasing compute capacity of high-performance systems enables scientists to simulate physical phenomena with a high spatial and temporal accuracy. Thus, the simulation output can yield dataset sizes of many ... -
Dynamically Scheduled Region-Based Image Compositing
(The Eurographics Association, 2016)Algorithms for sort-last parallel volume rendering on large distributed memory machines usually divide a dataset equally across all nodes for rendering. Depending on the features that a user wants to see in a dataset, all ... -
Efficient Remote Rendering Using Equirectangular Projection
(The Eurographics Association, 2017)Presenting high quality Virtual Reality (VR) experiences on head-mounted displays (HMDs) requires significant computational requirements. To ensure a high-fidelity experience, the displayed images must be highly accurate, ... -
Exploratory Performance Analysis and Tuning of Parallel Interactive Volume Visualization on Large Displays
(The Eurographics Association, 2015)We present an exploratory approach to performance analysis and tuning of interactive parallel volume visualization for large displays. While traditional approaches target non-interactive applications and focus on separate ... -
Extending X3D for Distributed Multimedia Processing and Control
(The Eurographics Association, 2009)Web-based applications of interactive 3D computer graphics are showing a tendency to get more interconnected and visually complex. Virtual communities like Second Life demand realism not only in terms of realistic rendering, ... -
Hardware Accelerated Medical Data Visualisation on the Web
(The Eurographics Association, 2012)This paper proposes a way to develop high-quality real-time web-based medical 3D data visualisation. Isosurface extraction is used as an example to discuss how to use programmable Graphics Processing Units (GPUs) and shaders ... -
Hardware-Accelerated Multi-Tile Streaming for Realtime Remote Visualization
(The Eurographics Association, 2018)The physical separation of compute resource and end user is one of the core challenges in HPC visualization. While GPUs are routinely used in remote rendering, a heretofore unexplored aspect is these GPUs' special purpose ... -
High-Performance Mesh Partitioning and Ghost Cell Generation for Visualization Software
(The Eurographics Association, 2016)Post-processing large datasets efficiently in parallel requires good load balancing of geometry supplied to the visualization pipeline. When datasets are not pre-partitioned or cannot be read back from simulation output ... -
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 ... -
Interactive Exploration of Gigantic Point Clouds on Mobile Devices
