VisNow concept was initially designed in the early 2000s by Dr Krzysztof Nowiński, based on his decades of experience in using computer graphics to visualize scientific data. The main reason VisNow was born were the limitations of the existing visualization platforms, significantly in High-Performance Computing.
VisNow is a generic framework for scientific visualization and visual data analysis. It follows a paradigm of a modular, dataflow driven system, where modules serve as functional nodes providing certain functionality in the visualization pipeline (e.g. data access, filtration, mapping, presentation), and connections between modules represent data. It is written entirely in Java programming language and is easily extendable to incorporate new modules and module libraries.
It was originally designed, developed and distributed as open-source software by the Laboratory of Visual Analysis at the Interdisciplinary Centre for Mathematical and Computational Modelling (University of Warsaw) where all the conceptual work and programming took place. Until 2020 approximately 1 million lines of code and 2,500 Java classes were developed around this project by ICM team to answer visualization and image processing needs of the scientific community.
In December 2019 visnow.org association was founded as a Non-Government Organisation in Poland with the goals of scientific visualization methods popularization, open visualization software development and promulgation and development of domain applications of visual methods, in particular within medicine and biomedicine.
Since then visnow.org confederates contributors for VisNow development and as a community supports source code and distribution of VisNow and its core libraries.
