  @inproceedings{v.20201195, abstract = {While visualisation often strives for abstraction, the interactive exploration of large scientific data sets like densely sampled 3Dfields or massive particle data sets still benefits from rendering their graphical representation in large detail on high-resolutiondisplays such as Powerwalls or tiled display walls driven by multiple GPUs or even GPU clusters. Such visualisation systemsare typically rather unique in their setup of hardware and software which makes transferring a visualisation application fromone high-resolution system to another one a complicated task. As more and more such visualisation systems get installed,collaboration becomes desirable in the sense of sharing such a visualisation running on one site in real time with another high-resolution display on a remote site while at the same time communicating via video and audio. Since typical video conferencesolutions or web-based collaboration tools often cannot deal with resolutions exceeding 4K, with stereo displays or with multi-GPU setups, we designed and implemented a new system based on state-of-the-art hardware and software technologies totransmit high-resolution visualisations including video and audio streams via the internet to remote large displays and back.Our system architecture is built on efficient capturing, encoding and transmission of pixel streams and thus supports a multitudeof configurations combining audio and video streams in a generic approac}, author = {Frieß, Florian and Müller, Christoph and Ertl, Thomas}, booktitle = {Proceedings of the Eurographics Symposium on Vision, Modeling, and Visualization (VMV)}, doi = {10.2312/vmv.20201195}, editor = {Krüger, Jens and Niessner, Matthias and Stückler, Jörg}, isbn = {978-3-03868-123-6}, pages = {127-135}, publisher = {The Eurographics Association}, title = {Real-Time High-Resolution Visualisation}, url = {https://doi.org/10.2312/vmv.20201195 }, year = 2020 }

  @article{9224182, abstract = {Collaborative exploration of scientific data sets across large high-resolution displays requires both high visual detail as wellas low-latency transfer of image data (oftentimes inducing the need to trade one for the other). In this work, we present a system thatdynamically adapts the encoding quality in such systems in a way that reduces the required bandwidth without impacting the detailsperceived by one or more observers. Humans perceive sharp, colourful details, in the small foveal region around the centre of the fieldof view, while information in the periphery is perceived blurred and colourless. We account for this by tracking the gaze of observers,and respectively adapting the quality parameter of each macroblock used by the H.264 encoder, considering the so-called visual acuityfall-off. This allows to substantially reduce the required bandwidth with barely noticeable changes in visual quality, which is crucial forcollaborative analysis across display walls at different locations. We demonstrate the reduced overall required bandwidth and the highquality inside the foveated regions using particle rendering and parallel coordinate}, author = {Frieß, F. and Braun, M. and Bruder, V. and Frey, S. and Reina, G. and Ertl, T.}, doi = {10.1109/TVCG.2020.3030445}, journal = {IEEE Transactions on Visualization and Computer Graphics}, pages = {1-10}, title = {Foveated Encoding for Large High-Resolution Displays}, url = {https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9224182}, year = 2020 }

We give a brief summary of related work for context and then focus on a comprehensive overview of the core architecture of the framework. This is followed by the existing and novel features and techniques in MegaMol that define its current functionality. MegaMol has originally been developed to support the visualization and analysis of particle-based data sets that, for instance, come from molecular dynamics simulations. Meanwhile, the software has evolved beyond that. New algorithms and techniques have been implemented to handle many diverse tasks, including information visualization. Additionally, improvements have been made on the software engineering side to make MegaMol more accessible for domain scientists, like an easy-to-handle scripting interface.}, author = {Gralka, Patrick and Becher, Michael and Braun, Matthias and Frieß, Florian and Müller, Christoph and Rau, Tobias and Schatz, Karsten and Schulz, Christoph and Krone, Michael and Reina, Guido and Ertl, Thomas}, doi = {10.1140/epjst/e2019-800167-5}, issn = {1951-6401}, journal = {The European Physical Journal (Special Topics)}, number = 14, pages = {1817--1829}, title = {MegaMol -- a comprehensive prototyping framework for visualizations}, url = {https://doi.org/10.1140/epjst/e2019-800167-5}, volume = {227: Particle Methods in Natural Science and Engineering}, year = 2019 }

This reduces the overall size of the image while preserving details. Our application determines the encoding settings in two steps. In the first step, we predict the quality and size of the tiles for different encoding settings using a convolutional neural network. In the second step, we assign the optimal encoder setting to each tile, so that the overall size of the image is lower than a predetermined threshold. Commonly, for tiles that contain complicated structures, a high quality setting is used in order to prevent major information loss, while quality settings are lowered for others to keep the size below the threshold. We demonstrate that we can reduce the overall size of the image while preserving the details in areas of interest using the example of both particle and volume visualisation applications.}, author = {Frieß, Florian and Landwehr, Mathias and Bruder, Valentin and Frey, Steffen and Ertl, Thomas}, booktitle = {Proceedings of the IEEE Symposium on Large Data Analysis and Visualization - Short Papers (LDAV)}, doi = {10.1109/LDAV.2018.8739215}, ee = {https://doi.org/10.1109/LDAV.2018.8739215}, isbn = {978-1-5386-6873-3}, pages = {87-91}, publisher = {IEEE}, title = {Adaptive Encoder Settings for Interactive Remote Visualisation on High-Resolution Displays}, url = {https://ieeexplore.ieee.org/document/8739215}, year = 2018 }
