Free 2d animation toolkit 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.

Medical Imaging Interaction Toolkit (MITK) is currently under active development, and aims at supporting the development of leading-edge medical imaging software with a high degree of interaction. It combines vtk, itk and the pic-based-libraries of the Div.
Main features:
- multiple, consistent views on the same data. For example, when you have three orthogonal 2D-views and a 3D view and data consisting of a green surface, the surface will be visible and green in all views (as contour lines in 2D, as a surface in 3D), and when you move the surface, it will move in all views. When you try to realize this with basic vtk, you will need to coordinate the position/orientation/color/... of all the views somewhere in your program - exactly this can mitk do for you.
- interactions that create and/or modify data (not only actors as in basic vtk)
- complex interactions with multiple states, e.g., for interaction with active contours
- undo/redo of interactions
- organization of data objects in a tree at run-time, e.g., to represent logical dependencies (e.g., a heart cavity is a part of the heart) or to control the rendering process
- additional properties of arbitrary type can be assigned to data objects contained in the data tree
- visualization and interaction with 3D+t data (basic vtk can handle only 3D data and itk is not for visualization and interaction)
- although mitk is mainly a toolkit and not an application, it offers some support on the application-level, e.g, for structured combination of modules (so-called functionalities), e.g., for combining and switching between one functionality for segmentation and another for registration.
Enhancements:
- New functionalities: IsoSurface, ViewInitialization and Measurement.
- Support for ITK 2.4-2.8, VTK 4.4 and 5.0.
- Lots of bugfixes and improvements, e.g. interaction for rotatable slices.

Seismic Toolkit 0.69a is designed to be a tool for processing and displaying seismic signal data in a graphical interface. Plot SAC ASCII and SAC_BIN data format, with zoom,unzoom, plot channel by channel, or plot all channel (until 2000, tested with 125).

Filtering the data: all filters are causal recursive IFR (Infinite Impulse Response) written using the bilinear Z-transform in the time domain. Their conception using a few number of coefficients gives them very fast with a low memory cost.

The adaptation factor of frequency warrants no deformation in the frequency domain of the transfer function. The main filters used are the following: Butterworth High-Pass and Low-Pass (n order), Farrer 10s-6s Low-Pass (a combination of rejector and Low-Pass specially designed for removing oceanic noise), Integrator, Derivator, Integrator with cut-off frequency, Derivator with cut-off frequency, Trend removing, Rejector (n-order), Envelop with Hilbert (not recursive at all), compensator of (n-order), Polynomial filter (n-order, not recursive at all ).

Major Functions:

1. Data plotting : channel by channel, all channels, zoom, unzoom, unfilter, instantaneous time and amplitude information with mouse pointer.
2. Fourier domain: Power Spectral Density (PSD) in linear-linear, log-log axes; independent windows for each channel, instantaneous frequency and amplitude information with mouse pointer, zoom, unzoom of spectra. Dirac, Hilbert transform, Time-Frequency representation (tested until 1 million of points per channel on 3 channels.
3. Polarization : easy and fast particule motion representation in both horizontal plane and incidence plane, with automatic computation of best direction with eigen vectors of the covariance matrix. Display of linearity and planearity coefficient.
   

Enhancements:

• New package (.deb) for Debian - Ubuntu
• New package (.dmg) for MAC OSX 10.4 (Tiger)
• Add function Derivator _Fc (a derivator with a cutting frequency
• Impose : setlocale(LC_ALL,"C") to avoid regional setting as decimal separator;

SJPT is parsing toolkit that supports both top-down (LL(1) and Simple Precedence) and bottom-up parsing (LR(0), SLR(1), LR(1) and LALR(1)).

The toolkit also supports generating Java parsers for all the bottom-up parsing methods, based on a CUP definition (similar to Yacc and CUP, but not restricted to LALR parsers only). I worked alone on this project for the laboratory on Compilers.

SJPT is free software under the terms of the GNU GPL.

PDF Toolkit is a simple servicemenu for PDF files.
Main features:
- give master password
- give user password
- allow only printing
- watermark
- extract a range of pages
- join PDF files

Term::Animation is a Perl module that provides a framework to produce sprite animations using ASCII art. Each ASCII sprite is given one or more frames, and placed into the animation as an animation entity.

An animation entity can have a callback routine that controls the position and frame of the entity. The module can also do collision detection between entities.

INSTALLATION

To install this module type the following:

perl Makefile.PL
make
make test
make install

DHTML Windowing Toolkit is a cross-browser JavaScript library for the creation of inline DHTML windows to contain content; windows that can be opened, closed, moved, and resized much like native windows.
Enhancements:
- Window objects can be created with the following features: open, close, minimize, restore, move, and resize.
- The following browsers are supported: Microsoft Internet Explorer, Mozilla Firefox, Opera, and Konqueror.

The Kiwi Toolkit project is a foundation class library containing many useful classes that complement the Java Foundation Classes (JFC).
It includes many classes and components that were not provided with the JFC, such as a TreeTable component, a DateChooser, an MVC charting package (bar charts, line charts, pie charts), a plugin framework for Java, an application resource manager (for loading images, icons, HTML pages, audio clips, and other resources from JAR files), a better internationalization API, and much more.
Enhancements:
- This release adds some new classes and includes various bugfixes.
