Free visualization library software for linux

The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing, and visualization used by thousands of researchers and developers around the world. Visualization Toolkit consists of a C++ class library, and several interpreted interface layers including Tcl/Tk, Java, and Python.
Professional support and products for VTK are provided by Kitware, Inc. VTK supports a wide variety of visualization algorithms including scalar, vector, tensor, texture, and volumetric methods; and advanced modeling techniques such as implicit modelling, polygon reduction, mesh smoothing, cutting, contouring, and Delaunay triangulation. In addition, dozens of imaging algorithms have been directly integrated to allow the user to mix 2D imaging / 3D graphics algorithms and data.
The design and implementation of the library has been strongly influenced by object-oriented principles. VTK has been installed and tested on nearly every Unix-based platform, PCs (Windows 98/ME/NT/2000/XP), and Mac OSX Jaguar or later.
Many resources exist to help you utilize the full potential of VTK in your application area. These resources include:
Mailing List: Over 1900 users are subscribed to this list. A great place to post questions, and search for answers.
VTK Textbook: The Visualization Toolkit, An Object-Oriented Approach To 3D Graphics, 3rd edition, ISBN 1-930934-12-2, now published by Kitware. This is a great book to read if you want to learn the details of the visualization algorithms and data structures. The book is often used as a college text in visualization and graphics courses.
VTK Users Guide: The Visualization Toolkit Users Guide, ISBN 1-930934-13-0, published by Kitware. This is the book to get if you want to learn how to install and use VTK.
ParaView Guide: The ParaView Guide, ISBN 1-930934-14-9, published by Kitware. ParaView is a turn-key visualization system build on top of VTK, and makes VTK easier to use with an interactive, point and click interface. ParaView also supports supercomputing applications, including tiled display and distributed parallel processing.
CMake: Mastering CMake, ISBN 1-930934-11-4, published by Kitware. CMake is the premier, cross-platform build system used to compile and link VTK. A useful book if you want to use VTK in your projects.
Support: A variety of support options are available ranging from the single point-of-contact Professional Subscription to get you up and running, to custom Site Support to help you develop your next product with VTK.
Enhancements:
- Many bugs were fixed, including fixes for memory leaks, array bounds errors, and stack overflows.

The Configuration File Library (CFL) is a collection of routines for manipulating configuration files. The project is a portable library fully written from scratch in pure ANSI C.

It is designed to offer for C programmers common routines for manipulating configuration text files.

Flate library is a template library used to deal with html code in CGI applications. The library includes C and Perl support. All html code is put in an external file (the template) and printed using the library functions: variables, zones (parts to be displayed or not) and tables (parts to be displayed 0 to n times).
Using this method you dont need to modify/recompile your application when modifying html code, printing order doesnt matter in your CGI code, and your CGI code is much cleaner.
Enhancements:
- can now include external files with #INCLUDEFILE /path/to/file.html

NTLM authentication library (libntlm) is a library that implement Microsofts NTLM authentication.
However, the packaging of libntlm lacked certain things, such as having build problems, lacking shared library support, lacking autoconf macro for use in other applications, lacking pkg-config support, and more. So this page distributes an improved version of the library; called Libntlm.
Libntlm is licensed under the GNU Lesser General Public License.
Projects using Libntlm include GNU SASL.
Enhancements:
- This release adds new APIs to access the SMBencrypt and SMBNTencrypt functions.
- The library is now linked with -no-undefined to enable building a Windows DLL.

CVS Perl library is a Perl module which is a wrapper around the CVS command with an object-oriented interface.

Installation:

To install this module type the following:

perl Makefile.PL
make
make test
make install

Java GetOpt library implements option parsing and a common online help behaviour, including an XML format for topics, command, and options (which can be queried with --help --xml) and support for online browsing with --help --browse.

Whats New in This Release:

ï¿1⁄2 The getopt library can now choose the pluggable look and feel of an application with a standard option "--plaf".
ï¿1⁄2 A new file of default options (.prefs/default.options) can specify a set of common default options for all programs using the getopt library, such as the PLAF.

Quantity/Formatter Library provides a Java library made with the quantity/formatter pattern..

Quantity/Formatter Library is a Java library developed in accordance to the quantity/formatter pattern (as demonstrated by the Date/SimpleDateFormat in the standard J2SE library).

The following quantity/formatter pairs are currently available:

Currency/CurrencyFormat,
Density/ DensityFormat,
Dimension/DimensionFormat,
Distance/ DistanceFormat,
ElapsedTime/ElapsedTimeFormat,
Temperature/TemperatureFormat,
Volume/VolumeFormat
Weight/WeightFormat.

Java DIME Library project implements Direct Internet Message Encapsulation (DIME), which is a lightweight binary encapsulation format that can be used to encapsulate multiple payloads of arbitrary types and sizes into a single message.
DIME is ideal for incorporating binary attachments into any XML-based protocol. The library fully supports the latest DIME specifications.
Enhancements:
- Corrected DimeRecord.isFirst() thanks to John Russell
