Free visualization tools software for linux

Chaos Visualization is a program for quickly calculating the amount of predictability in a very simple system: a spring with one side connected to the origin and the other to a weight under gravity.

This amount is chaos is visualized in TIFF images, which can be put in a sequence to show the evolution of chaotic behaviour in this system.

Genomorama: Genome Visualization is a multi-scale, multi-genome, multi-platform visualization and analysis program. It provides a powerful yet easy to use interface that leverages the visualization power of modern computers (via OpenGL) and the substantial bioinformatic infrastructure provided by the NCBI (via the NCBI C toolkit).
Genomorama is written in portable, highly optimized C++ and comes in three "flavors" that allow it to run natively on (most) modern operating systems: OS X (using Carbon), Microsoft Windows (using MFC), and Linux (using Motif). Executables and source code are freely provided for all flavors.
Main features:
- High performance has not been sacrificed on the altar of portability
- OpenGL graphics take advantage of the video-game optimized graphics cards available in most desktop and laptop computers.
- C++ allows transparent and complete utilization of system resources (like memory).
- Native windowing toolkits (Carbon, MFC and Motif) for every operating system facilitate responsiveness and ease of use.
- A stand-alone, self-contained executable frees Genomorama from dependence on third party applications.
- Source code for all platforms is freely available.
- An attractive, full featured user interface
- Genomorama presents a clean, uncluttered user interface.
- Multi-scale rendering displays relevant details while maintaining readability.
- Use a keyboard or a mouse to efficiently zoom, pan and explore genomes of arbitrary size.
- Attractive WYSIWYG Postscript and GIF output formats yield publication quality images.
- Novel features to aid genome analysis
- In addition to the standard searching options (like query by sequence and gene name), Genomorama offers "forward and reverse" DNA hybridization based searches.
- Provide a pair of PCR primers, and Genomorama will output the amplicons.
- Provide a hybridization probe and Genomorama will find binding sites.
- Provide a pair of Padlock probes and Genomorama will identify binding locations
- Provide a set of PCR primer criteria (length, melting temperature, base composition, etc.) and Genomorama will find PCR primers.
- Genomorama can display and search an arbitrary number of genomes (limited only by computer memory).
- Harness the power of the NCBI toolkit to directly access and search the NCBI Entrez database.
- Compute melting profile, in addition to traditional base composition plots (i.e. %G+C, %A+T, etc).
Enhancements:
- This release fixes the following bugs: parsing gbk files that contain single base annotations on the complement strand;
- missed exact matches at 3 end of target sequence;
- fragile parsing of annotation range;
- downloading of very large Genbank records (i.e. human chromosomes);
- and omitted intergenic space following single base annotations (i.e. SNPs).
- Custom color records are now saved to and read from GBK files.
- An OS X Intel-specific executable has been added.
- The information dialog box has been made resizable.

Chess Training Tools is a collection of chess training tools. It includes a chess visualization trainer that teaches chess visualization by drilling you on the color of a particular square, and also on your ability to tell if two squares are the same color, if two (or three) squares are on the same diagonal, if two squares are a knight move apart, or if two squares are two knight moves apart.
This is a program that I wrote for my own use to improve my chess visualization ability. I decided to share it with other players, since I believe they can benefit from it. It basically helps you remember what color the squares are, how the pieces move, and so on, all in your head.
It does so by posing you various excercises that, if practiced every day, will let you visualize positions without the aid of a board.
I use this tool every day. You may want to use it the way I do, or you could develop your own method of training. I work my way through the panels, doing 20 of each excercise. I proceed Color->Same Color->Diagonal 2->Diagonal 3->Knight->Knight 2->Mate.
Then, after all of that I play a game against Vince. Start slow, by either lagging the display by one ply, or by blanking out one quadrant. Work your way up to the 7 ply and four quadrants.
Enhancements:
- This release added undo, or move takeback to the PlayTest ("Vince").

GeoVISTA Studio is an open software development environment designed for geospatial data. GeoVistaStudio is a programming-free environment that allows users to quickly build applications for geocomputation and geographic visualization.
One barrier to the uptake of Geocomputation and Geovisualization is there is no system or toolbox that provides easy access to useful functionality. GeoVISTA Studio provides rapid, programming free development of complex applications for:
- data exploration
- knowledge construction
- geocomputation
- visualization
Studio Includes Interactive Query Devices for Exploratory GeoVisualization, 3D Render for complex and sophisticated 3D graphics, 2D mapping and statistical tools.
Studio provides a:
1. Visual Programming-Free Environment for rapid development.
2. Component-Oriented Programming: uses JavaBeans as programming components. Any JavaBeans (developed by 3rd parties) can be plugged in!
3. Recursive Development turns a developed application into a JavaBean component. Developed components (applications) are reusable (scalable), and developed components can be shared by other Studio users and/or java programmers.

VICS-II project is the next generation of VICS, which was originally developed by Fujio Izumi and Ruben A. Dilanian as a part of VENUS. VENUS stands for Visualization of Electron/NUclear densities and Structures.
They started VENUS project in mid 2001. Although basic features were almost completed when I first knew about VENUS at the end of 2003, early version of VICS/VEND had serious performance issues and could not run well on my PC. So I started checking the sources and tried to fix it.
I committed some fixes to them but could not fix all issues because some of them are originated in programing model and some are originated in toolkit itself. At the end of June 2004, one of the main developer Dilanian leaved the project and both VICS and VEND became unlikely to continue its progress.
Then I decided to create new programs from scratch using some of original code and new toolkit called wxWidgets.
VICS-II runs on Windows, Mac OS X, Linux, and is contributed free of charge for non-commercial users.
The VENUS package comprises four independent programs:
- VICS: VIsualization of Crystal Structures
- VEND: Visualization of Electron/Nuclear Densities
- PRIMA: PRactice Iterative MEM Analyses
- ALBA: After Le Bail Analysis

ORFEO Toolbox (OTB) is a high resolution remote sensing image processing library. It contains a set of algorithmic components which allow the user to capitalize on methodological know how, and therefore use an incremental approach to profit from the results of methodological research. The project is made of a set of basic elements (a C++ class API) and utilities (independent programs built upon the base API).
Enhancements:
- This release adds various bugfixes, support for VC++ 7.1 and 8.0, Cygwin, and MinGW, several new image formats (Erdas HFA, Lum), multiscale analysis (morphological pyramid) and spatial reasoning (RCC8), improvement of the visualization, and new applications.
