...The toolbox offers advanced analysis methods of MEG, EEG, and invasive electrophysiological data, such as time-frequency analysis, source reconstruction using dipoles, distributed sources and beamformers and non-parametric statistical testing. It supports the data formats of all major MEG systems (CTF, Neuromag/Elekta/Megin, BTi/4D, Yokogawa/Ricoh, FieldLine) and of most popular EEG systems, and new formats can be added easily. FieldTrip contains high-level functions that you can use to construct your own analysis protocols in MATLAB. Furthermore, it easily allows methods researchers to incorporate new methods for EEG/MEG analysis.

jSNARK is an extensible programming system designed to help researchers interested in developing and evaluating algorithms for reconstructing 2D, 3D and even 4D (the extra dimension is time) images from their projections.

MathMod is a portable interactive plotting and graphing program for Windows, Linux, MacOSX and many other platforms. MathMod allows to plot 3D mathematical surfaces, described by implicit or parametric equations, and offers a very large database of model samples that can be generated with it. It's Free and Open Source. Change-log for MathMod-13.0 (15/11/2025) 1) Scripts generator to add thickness to iso/parametric surfaces 2) Undo/Redo commands for navigating through previous...

...K3DSurf supports Parametric equations and Isosurfaces. ****** Welcome to the realm of complex numbers! Change-log for MathMod-11.1 (16/06/2021) 1) Support of graphing functions with complex numbers Z=u+iv in 3D and 4D spaces (demo scripts: "Complex3D_xx" and "Complex4D_Saddle") 2) Added support for HSV (hue, saturation, brightness) coloring model (script: "Complex_Domain_Coloring") 3) Texture definitions (RGB and HSV) for parametric surfaces can now be expressed as functions of complex numbers 4) Added a software implementation for the OpenGL variable gl_FrontFacing (fixed an issue with GPU drivers on MacOSX Catalina). ...

GXSM -- Gnome X Scanning Microscopy: A multi-channel image and vector-probe data acquisition and visualization system designed for SPM techniques (STM,AFM..), but also SPA-LEED/LEED/LEEM data analysis. A plug-in interface allows any user add-on data-processing and special hardware and instrument support. Latest: NC-AFM and related explorative methods as SQDM can be configured. High-Speed external PAC-PLL hardware option with digital DSP link. Based on several hardware options it supports...

...Polarized (+/-) geometries for all shapes are included as an option, including special tools to work with both negative and positive numbers that appear in the revolving geometry display. A novel colorization system and graphic control system was employed, in order to visualize 3D or 4D Pascalloids.

This is a very simple OpenGL visualization library with a 3D and 4D volume renderer. It can easily be reused in other projects (e.g. with medical volumes). It is just perfect for learning or great if you like to hack your own code.

CamBA is a Linux package for statistical analysis, by script/GUI, of neuroimaging data (fMRI/sMRI), developed at the Brain Mapping Unit, University of Cambridge. Non-parametric permutation-based statistics. Input images: 4D NiFTI files, output: HTML/

Worldlines visualizes special relativity, as particles near lightspeed trace paths in a 3D slice of 4D Minkowski spacetime. Scenes illustrate time dilation, the twin paradox, length contraction, and Bell's spaceship paradox.

Simulated annealing for cell tracking (assignment problem in 4D) with scheme for removing low energy nodes from consideration ("quenching").

Vurtigo is a 4D (3D + time) real-time visualization software for guiding cardiovascular interventions. It is primarily intended for use with a magnetic resonance imaging (MRI) scanner, and also actively tracked catheters and navigational devices. The latest releases are not available on sourceforge; check out the vurtigo.ca link below for the most up-to-date version.

4-Dimensional Cell Simulator (4DiCeS) is a framework on hybrid (stochastic and deterministic) modeling and simulation of (whole) cell environments in 4D. The framework may incorporate any reaction and diffusion algorithms applicable in a 4D grid layout.

KU1K is a set of tools for 4D,5D and 6D compact U(1) lattice gauge theory Monte Carlo simulation using the Skipis-Vantzos algorithm. As the calculations involved, even for the 4D case, are consuming, the project is modular so as to run on the Grid.

A java program for exploring cubic fractals, similar to the Mandelbrot set but exhibiting a higher level of dynamical complexity. CubicBrowser provides the ability to explore the 4D Cubic Locus (and associated Julia sets) by viewing arbitrary 2D slices.

The fst2v5d package converts data stored in the Canadian RPN Standard File (FST) format into Vis5D format. FST files, commonly used to store meteorological data, are scanned by fst2v5d to generate both 4D fields and independent topography input files.
