Software oscilloscope using Python and tkinter. Supports multiple sources: socket, file, audio, USB. Displays data by samples, time or frequency. Scales the input automatically or manually.

qliss3d renders 3d-Lissajous-figures (figures made of a different sine functions for each dimension) with a Qt interface. You can look at the figures from any viewing position you like and even "listen" to the sound of the figures.

surf is a tool to visualize algebraic curves and algebraic surfaces. It is written in C++. The GUI is written using the Gtk widget set.

surfit is an open source and free gridding and contouring software. surfit can do interpolation/approximation of points, contours and surfaces, can take fault lines and trend surfaces into account, can use inequalities and other conditions. Supports a lo

Cracks of Reality is a high-quality fractal image renderer for Mac OS X. It is written in ObjC/Cocoa with the core engine in C to allow for a portable command-line version. Goals are speed, quality, and the ability to import other programs' descriptions.

3D viewer which arranges BLAST hits and other bioinformatics-related alignments in a rotating, cylindrical display. Feedback appreciated. NOTE: requires Java3d installation. Superceded by Cylindrical Alignment App

DSAquire allows you to download and plot trace data from a Thurlby DSA524 digital storage adaptor (it's a 25 year old instrument, but better late than never, eh?). The data is downloaded via an RS232 serial link using a null modem cable. You can export the plot as an image or export the data in real-world units as a csv file. This software runs under Linux and also under Windows XP and later using Cygwin. Pre-compiled binaries are supplied, as are full sources under the GPL. The interface of provided via FLTK. Also hosted here are the service and operators' manuals for this instrument, as well as dumps of the firmware from the EPROM. Many thanks to those who have preserved these for posterity (the 2.79 and 2.86 firmware dumps where generated by me - the rest has been collected from around the 'net).

Webite: http://flowbasedprogramming.com DSPatch, pronounced "dispatch", is a powerful C++ dataflow framework. DSPatch is not limited to any particular domain or data type, from reactive programming to stream processing, DSPatch's generic, object-oriented API allows you to create virtually any dataflow system imaginable. *See also:* DSPatcher ( https://github.com/MarcusTomlinson/DSPatcher ): A cross-platform graphical tool for building DSPatch circuits. DSPatchables ( https://github.com/MarcusTomlinson/DSPatchables ): A DSPatch component repository.

A cross-platform terrain rendering engine that uses advanced techniques such as dynamic tessellation to render complex landscapes at high frame rates. Suitable for use in games, engineering, simulation, etc.

Emma (Extensible Multi Media Architecture) is an open-source, modular, extensible, dynamic framework for declarative authoring and display of 2D and 3D interactive multimedia. It uses Lua for scripting and Ogre3D for rendering. http://www.emma3d.org

FrAid(FRactal AID) is an interface to Java, allowing it to proc. math. data(functions/equations). A compl. standalone system utilizing the FrAid prog. lang. is available(no need to be Java programmer to use it!). Use instead of Matlab. High res. graphics

Fractal Explorer supporting FTF and common .NET standard supported formats

FMC will provide a Model-View-Controller architecture for developers to make Freality: an extensible metaverse, for gaming, socializing, exploration and pretty much everything under the virtual sun.

FreeMovie is an SWF generator library written in PHP and ported to Ruby. FreeMovie can be used to develop Web and desktop aplications.

GEM for Max/MSP is Max(cycling'74) external objects to render OpenGL-based graphics. This project is to port of GEM originally coded for pd (puredata).

Library intended for construction, evaluation, manipulation and visualization of geometric objects, especially for parametric and implicit defined surfaces

Height Map Editor is a program meant for editing, generating and manipulating height maps (terrains) that can be used in terrain rendering engines, or even as clouds.

Ink9000 is software designed to create non-photorealistic graphic novel style images from 3D models using OpenGL

JMicroPolygon is a project to provide polygon drawing and filling facilities for J2ME (MIDP 1.0 and 2.0) without relying on extension APIs.

JSynoptic renders information graphically. It can be used as a simple graph plotter, or as a complex run-time monitoring environment. The user sets up shapes (like plots) on graphical pages, and uses data sources (ex: ASCII file) to render information.

Experimental Lindenmayer System generator, in 3D using OpenGL. Used for modeling the fractal growth processes of plants.

The Landscape Composer is an experiment for the visualization of nature scenes in real-time. Emphases are among other things the modelling of trees and fields.

LeafAnalyser has been developed as a fast throughput leaf shape analysis application. It contains features such as automated image processing, data analysis and interactive 2D/3D graphs.

LinSAP is a cross platform, user-friendly, interactive structural analysis program designed to be used by civil engineers. It focuses on constructional analysis using matrix method to find forces at the connections and display the results

A Java based molecular modeling program. Has support for generating movies by interpolating between given positions, interactive display and manipulation of atoms and bonds, and dynamic modeling of substance formation.
