Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.
San Le's Free Computational Electromagnetics (SLFCEM) is a package of scientific software for use in computational electromagnetics. Command-line driven calculation engines are separate from the GUI components and can be used independently. It includes two of the basic finite elements types, 4 node quad and 3 node triangle. Each element type has a unique GUI specific to the element. Modal analysis for solving the waveguide problem is done using edge based elements. There is also code for generating edge connectivity. The algorithm used is a combination of Lanczos for tridiagonalization of the system, as well as QR to calculate the resulting eigenvalues. In addition to skyline storage and LU decomposition, calculations are also made using the Conjugate Gradient Method.
GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
ArtTk is a graphic library based on Java/Swing offering an open development toolkit intended specifically for scientific and technical applications. It provides a set of widgets and functional modules a set of support modules (helpers) permitting dynamic definition of menus and tool bars from simple XML configured files, and supporting tooltips, icons, action commands, etc.; a very adaptable generic desktop, facilitating the assembly of Swing components in a specialized GUI; an extended Grid layout to simplify the development of advanced scientific applications; and a set of scientific and technical widgets, such as a dynamic memory footprint monitor, simple key-values based fields editors, a generic color gradient editor, etc.
ViTables is a graphical browser for HDF5 and PyTables databases. It can open arbitrarily large files and browse their data and metadata in a variety of ways. Its capabilities include easy navigation through the data hierarchy, displaying of real data and its associated metadata, and simple yet powerful browsing of multidimensional data.
Fluere is a graphical software package for particle image velocimetry (PIV). Fluere is highly optimized for parallel processing and runs on multiple platforms. The goal of the project is to provide researchers and educators with high-quality velocimetry software that incorporates the latest advancements in PIV processing, while having complete knowledge of the algorithms used.
GraphInsight is visualization software that lets you explore graph data through high quality interactive representations. Data exploration and knowledge extraction from graphs is of great interest nowadays: knowledge is disseminated in social networks, and services are powered by cloud computing platforms. Data miners deal with graphs every day. Humans are extremely good at identifying patterns and outliers. Interacting visually with your data can give you better intuition and higher confidence in what you are looking for.
