Free legend software for linux

Swing Glue is an ultra thin layer that allows to decouple view, controller and model into separate individual domains.
It as not just another framework as you might think now. It is an very generic layer that has a minimal impact to the application where swing glue is used.
Main features:
- Object repository that minimizes transport of references
- automatic population of Adhesive class members from the repository
- abstraction of view code and event code
- no wrapping component classes, you still use the normal Swing classes
Swing Glue is proof for the legend that a framewok does not necessarly has to be a Bloat of code that helps you to simplify your development.
It also works with a simple framework that is non evasive and has a very simple code base.

Racer is a free car simulation project, using real car physics to get a realistic feeling. Cars, tracks, scenes and such can be created with relative simplicity in mind (compared to other driving simulations).
The 3D and other file formats are, or should be, documented. Editors and support programs are also available to get a very flexible and expandable simulator. It uses OpenGL for rendering.
It attempts to do well at the physics section, trying to create life-like cars to emphasize car control and doesnt cut back on realism in the interest of fun. If youve played Grand Prix Legends from Papyrus, youll know what Im talking about.
Racer major features:
- Its totally free! (for non-commercial use)
- Available for multiple platforms; Windows 2000/XP (95/98/ME may work but have some trouble with fonts), Linux and Mac OS X.
- 6 DOF models used (the car can move around freely)
- Uses motion formulae from actual engineering documents from SAE for example.
- Total flexibility; almost everything is customizable through ASCII files.
- Commercial-quality rendering engine (with smoke, skidmarks, sparks, sun, flares, vertex-color lit tracks).
- Support for Matrox Surround Gaming. See the corresponding page on Matrox site.
- Lots of addon cars and tracks available on the web.
- Easy integration of your own cars and tracks that you create in ZModeler, 3D Studio Max(tm), Maya etc.
- At least 15 degrees of freedom for a regular car (6 DOF for the car body, 1 for each wheels vertical motion and 1 for each wheel spinning, and 1 for the engine, several more for the driveline). Depending actually on how many wheels you put on the car.
- Real-time internal clock; no physical dependency on framerate. Controller updates are also done independently of the framerate.
- Not limited to 4 wheels; anything from 2 to 8 wheel vehicles are currently supported (but mostly untested, and some problems with hardcoded differentials for example may exist (v0.5.0)).
- Not much constraints on the track data; surface info is taken from polygon data (VRML tracks), and splines are used to smooth out the track surface (polygons are too harsh for driving on just like that).
- Tools to modify the cars & tracks are freely available on this site (though external utilities are recommended for best results).
- Some used algorithms are explained on this site. Also, references are available. If you are programming a carsim, you might find something useful here.
- Save game present!
Main features:
PHYSICS FEATURES
- Full 6 degree of freedom motion of the car chassis.
- Independent suspension for all wheels.
- Suspension features: springs, dampers, anti-rollbar, rollcenter, anti-pitch.
- Wheel features: camber, wheel hop (the wheels have mass), toe.

- Shader system for Quake-style rendering.
- Fog definable per track.
- Environment mapping for shiny materials.

PlotMM is an extension to GTKmm which provides a 2D data plotting widget. PlotMM is an extension to the gtkmm library. It contains widgets which are primarily useful for technical and scientifical purposes. For the beginning, this is a 2-D plotting widget (see screenshot above).
Main features:
- Plot Widget with tick marks, tick labels, axis labels, a title and an optional selection rectangle (grid and legend will be added soon)
- curves for 2D-data with and without errorbars; the curves can be drawn using various curve styles and symbols, each with different colors
- axes have automatic major and minor tick generation for linear and logarithmic scales and provide autoscaling
- signals allow to handle mouse events from the plot canvas
- a simple example application demonstrates the use of the PlotMM classes
Enhancements:
- This release adds compatibility with gtkm-2.4/2.6 and fixes several bugs.

Kpl is a program for the KDE project (K Desktop Environment). Kpls purpose is the two- and three-dimensional graphical presentation of data sets and functions.
Multidimensional nonlinear parameter fits of functions to data sets can be performed using the Levenberg-Marquardt algorithm. Also general linear least square parameter fits are possible.
A DCOP interface can be used to control Kpl by other applications and scripts.
All settings necessary for a complete description of the presentation can be saved in plot files. These files as well as data files may be chosen by command line parameters, using the File menu, or by drag and drop.
Automatic scaling and normalization allow the easy graphical presentation of data. Also parameter fits can be performed automatically.
The settings of a presentation may be changed using the Edit menu. Here also additional data sets and functions can be included which can be displayed in the same as well as in different data windows.
Currently language support is given for english and german.
Kpl is free software, released under the GNU General Public License.
Enhancements:
- Multiple spline items can be fitted simultaneously to the same array item.
- Colored symbol pixmaps are displayed in item list.
- Text of legend and text items is displayed in item list.

QwtPlot3D is a Qt/OpenGL-based C++ programming library, providing essentially a bunch of 3D-widgets for programmers.
Main features:
- Common code base for Qt3 and Qt4
- Specialized widgets for surfaces, graphs etc.
- Parametric Surfaces
- Lighting (experimental)
- User defined visual objects
- Scaling, rotating, shifting, zooming of data sets and mathematical functions ( see Data Input Topics )
- Interactive mouse and keyboard handling
- Resolution changing on the fly
- Reading from MESH data files :See the data directory and NativeReader documentation for this . You will find example datasets here
- Reading from FEM files
- Flat (2D) labeling
- Wireframe, filled polygons, hidden line
- Floor projections (Isolines, Data)
- Free configurable (labeling, numbering; linear, log or user-defined transformations) and autoscalable axes
- Free color model

- Pixmap output (all Qt supported formats)
- Vector output (PostScript, EPS and PDF) via gl2ps

Helherron is a fantasy RPG game for PC computers.

The isle of Helherron is at chaos. Beloved King Krohl has been kidnapped. Nobody knows by whom, but the legends are wild. The villagers tell, still shaking in terror, that it was done by dark, winged man-like creatures that took off to the sky shrieking, with poor King Krolh with them.

And worse yet, the isles seem to be cursed somehow. Its hard to determine how, but you sure can feel it. It hangs in the air heavy, like a Shadow of Death, and you can see it shimmering bloody red in the horizon of the night sky.

The villagers tell that just lately, after King Krolh was kidnapped, their villages have been raided by grotesque cross-breeds between man and beast. Most apparently that is also due to the Curse placed over Helherron and its sister isles. But the worst is yet to be told.

The Divine Sceptre, given to the people of Helherron by the Divine Cleric Order and crafted by the Creator itself, which was at King Krolhs possession, is now missing too. It was most apparently stolen at the same time King Krolh was kidnapped. Thus, the only hope for Helherron is to send a party of heroes to find the Divine Sceptre so that order and peace can be once again returned.
