A library and reference application for viewing and analysing raster and vector geospatial data.

The software package 'relax' is designed for the study of molecular dynamics through the analysis of experimental NMR data. Organic molecules, proteins, RNA, DNA, sugars, and other biomolecules are all supported. It supports exponential curve fitting for the calculation of the R1 and R2 relaxation rates, calculation of the NOE, reduced spectral density mapping, the Lipari and Szabo model-free analysis, study of domain motions via the N-state model and frame order dynamics theories using anisotropic NMR parameters such as RDCs and PCSs, the investigation of stereochemistry in dynamic ensembles, and the analysis of relaxation dispersion data.

Cca-forum unifies the Common Component Architecture tools and tutorial. It includes the CCA specifications, the Ccaffeine framework for HPC, and related tools. These support multilanguage scientific and parallel computing.

WaveSorter emphasizes dynamic visualization and versatility. Slider controls let the user select any coefficient or sample from any of several transforms, which can then be plotted to either axis of a 2D histogram (scatterplot). Within the waveform space, cursor-based controls let the user select subregions of the waveform space or individual waveforms to view. The user may cluster waveforms manually or via one of several popular clustering programs. The classification along with waveform properties (width, etc.) can be saved to disk in simple text files. WaveSorter is written in C++, utilizes the GNU Scientific Library for all computation, and is highly parallelized; on modern hardware it can handle files containing several 100,000s of waveforms per channel with almost no noticeable loss in GUI fluidity and <1sec lags for files with >1,000,000 waveforms per channel. It can be run in batch mode. It supports a wide array of binary file formats as well as ASCII text.

CanFestival focuses on providing an ANSI-C platform independent CANOpen stack that can be implemented as master or slave nodes on PCs, Real-time IPCs, and Microcontrollers. A WxPython based CanOpen Object Dictionary editor GUI is also provided.

TerraVision is a real-time multi-threaded 3D terrain visualization system. It can browse massive terrain and other data sets that are streamed over the Web. It also supports overlaying rich 3D models on the terrain to represent buildings, icons, etc.

EasyChem is designed to draw chemical molecules in an intuitive way, with a very high quality (designed for book-publishing). Exporting is done to various formats (PostScript, Fig, LaTeX, etc.) to help you integrate your drawing in any software you use.

Avenzoar is a one-year exploration of renal cell carcinoma morphology and its related single nucleotide polymorphisms (SNPa) as a method of automating diagnosis of cancer by using a computer-aided decision tree controlled by analytical statistics.

FElt is an open source system for finite element analysis, primarily for mechanical problems. FElt includes command line tools, an X11 interface for pre- and post-processing, and a Windows editor interface with some post-processing capabilities.

Viewstl is an open source way to view Stereo Lithography Files as shaded on-screen images. Ascii STL files and dynamic rotation, scaling, and panning are currently supported. Written in C using OpenGL, GLU and GLUT.

Ultrascale Visualization Climate Data Analysis Tools (UV-CDAT), is a powerful and complete front-end to a rich set of visual-data exploration and analysis capabilities well suited for climate-data analysis problems.

Varkon is a very powerful parametric 2D/3D CAD, modeling and application development tool for engineering, design, architecture, etc. It does 2D drafting, 2D and 3D modeling, sculptured surface modeling, and even animations. See our website for details.

A 2D scientific plotting library built on cairo. Provides uniform output to pdf, ps, png and X-Windows. Written in C with no dependencies (other than cairo) as a direct replacement for PGPLOT.

An automatic 2D Delaunay mesh generator and solver for Finite Element Analysis. Can solve 2D field problems (Poisson and Helmholtz Equations). Can use LAPACK/ARPACK solvers producing OpenGL/Postscript output. Uses C/GTK/GTKGLExt/MFC. Runs on Win32/Unix.

Quickplot is a fast interactive 2D plotter with infinite zooming, value picking, pipe input, and unlimited plots displayed. Quickplot is meant for looking at your data quickly and of secondary importance is making static pictures of your data.

CartoReso intends to facilitate enterprise computer network mapping.

Note: The Functy and libsymbolic code has now moved to GitLab: https://gitlab.com/flypig/functy https://gitlab.com/flypig/libsymbolic This project has been left here for archival purposes. Functy is a 3D graph drawing package. It allows Cartesian, spherical and parametric curve functions to be plotted and altered quickly and easily. This immediacy and the vivid results promote fun exploration of 3D function. Rendering is performed entirely on the GPU to improve visuals and performance.

NanoCap is a generic application for the construction of low energy fullerene and capped nanotube structures. It provides an ideal tool to accompany the study of finite carbon molecules using computer simulation. The implementation involves a standalone application which includes a GUI and allows for dynamic visual inspection through 3D rendering. In addition, the NanoCap core libraries can be used in custom Python scripts that enabled the user to produce structures in bulk or to include the structure generation routines into pre-existing code.
