VisNow - a generic data visualization platform

VisNow is a generic visualization platform in Java technology, developed by the Laboratory of Visual Analysis at the Interdisciplinary Centre for Mathematical and Computational Modelling at the University of Warsaw.
It is a modular data flow driven platform enabling users to create schemes for data visualization, visual analysis, data processing and simple simulations. Motivated by 'Read and Watch' idea, VisNow shows the data as soon and fast as possible giving further opportunity for processing and more in-depth visualization. In a few steps it can create professional images and movies as well as discover unknown information hidden in datasets.

VisNow, not trying to be yet another visualization tool, is targeted at overcoming the drawbacks of other similar software platforms. It is subject to the following keynotes:

  • Clear and legible desktop
  • Network creation support
  • Multifunctional modules
  • Module-Object-Interface connection

VisNow v1.3.1 available

Saturday, 09 November 2019

VisNow v1.3.1 is available for download NOW! Go to the download section to get the installers for Linux, Windows or macOS.


This is still VisNow in the full version with all functionalities. Within this release, we've focused on improving the support for large regular fields and fixed a bunch of bigger and smaller bugs. 

Major changes: Improved large data support; The new interface in component calculator module; Added support of coordinate units; Added support of large 3D fields in the image reader; Lots of bugfixes.

Major bugfixes: Solved thread deadlock on newer Linux systems; Solved number of issues on newer macOS systems; Fixed some bugs in the stationary flow visualization module; Fixed interpretation of 16-bit DICOMs.

VisNow tutorial at Supercomputing Frontiers Europe 2019 conference

Tuesday, 05 March 2019

Supercomputing Frontiers conference is coming next week to Warsaw, Poland again - as SCFE 2019. This second release of SCFE conference again will become a place of visionary look at the future of supercomputing. The tutorials programme this year covers programming with Julia, programming with Adios and introduction to visualization with VisNow. Participants of our training will be able to work with VisNow v1.3 version, with a number of new functionalities like physical units support, new probing modules or integrated flow visualization module.

Visualization workshop for Cardinal Stefan Wyszynski University

Monday, 22 October 2018

Ph.D. students from the Cardinal Stefan Wyszynski University in Warsaw, Faculty of Mathematics and Natural Sciences, School of Exact Sciences, took part in the scientific data visualization workshop organized by the Interdisciplinary Centre for Mathematical and Computational Modelling. The participants had the opportunity to use VisNow to learn on best practices in scientific visualization on real-world case studies. "I'm highly impressed by the ICM Technology Centre and the classes. Both presentations and practical activities with VisNow were prepared and presented professionally" said one of the participants.  

VisNow tutorial at Supercomputing Frontiers Europe 2018 conference

Thursday, 15 March 2018

Supercomputing Frontiers conference was held for the first time in Warsaw, Poland as SCFE 2018. Its is the place to be for visionary look at the future of supercomputing. Between many tutorials (including quantum computing by D-Wave or programming with Julia) VisNow also found its place. Participants were able to work with VisNow v1.3-RC1 (release candidate) version, coming soon to full release, and providing a number of new functionalities like physical units support, new probing modules or integrated stationary flow visualization module.

VisNow at SC17 conference

Monday, 20 November 2017

VisNow was present at SuperComputing 2017 conference in Denver in three flavors - ICM booth and two live demos. Based on fast global connections a globally distributed visualization was presented in first demo, based on NICE DCV engine with VisNow as a visualization layer. In the second demo VisNow enabled a 3D insight into a deep learning network decision process in Achilles tendon imaging.
