Free zooming predictive software for linux

OpenBerg Reader is an open-standards-based, multi-platform eBook reader.
The objective of the OpenBerg project is to design and implement open-source tools for the creation, edition and usage of open-standard eBooks.
We are currently developing the OpenBerg reader, an advanced eBook reader based on Mozilla technologies. This reader will allow, among other features, rich eBook contents, semantical find facilities and reader annotations, in a multi-language environment.
This program is developed Linux and Windows, using cross-platform technologies available for Linux, Windows, MacOS X, OpenBSD, FreeBSD... If you wish to contribute or donate, do not hesitate to contact us. We need developers and beta-testers on all these platforms, as well as package, website and documentation maintainers. Soon, hopefully, we will also need help with translation. Last but not least, we need help to spread the word.
Enhancements:
- This release is the first in a new generation of OpenBerg Reader / Lector.
- It enriches Firefox with the ability to read several formats of e-Books, while using all the usual features of Firefox, including printing, bookmarking, following hyperlinks, zooming in or out, copying or exporting parts of the book, etc.
- With the right (existing) Firefox extensions, you can even take yellow-sticker-notes on e-Books, add and share comments on chapters, have your book read out to you, etc.

Zoom is a player for Z-Code stories or games. These are usually text adventures (interactive fiction), and were first created by Infocom with the Zork series of games.

Throughout the 80s, Infocom released many interactive fiction stories before their ambitions to enter the database market finally brought them low.

Zoom has versions for OS X and Unix-like operating systems using X-Windows. You can download the OS X version or the source code using the links to the left. Zoom can be redistributed under the terms of the GNU General Public License.

Obviously, Zoom is quite capable of playing Zork, so those of you who have access to the increasingly rare Infocom games can continue to play them. However, back in 1993, Graham Nelson released Curses and more importantly the Inform compiler that created it. There is now a considerable collection of new interactive fiction of variable quality available. Bafs guide to the interactive fiction archive is absolutely essential for those new to the scene.

Looking Glass is a project that allows creating an innovative 3D desktop environment for Linux. It is sponsored by Sun Microsystems.

Looking Glass is programmed in the Java language using the Java 3D system to remain platform independent. Despite the use of graphics acceleration features, the desktop explores the use of 3D windowing capabilities for both existing application programs and ones specifically designed for Looking Glass.

The project is still in early development. The prototype is now working on Suns Java Desktop System.[citation needed]

One of its most notable features is the creation of reversible windows. This capability can be used for features like allowing the user to write notes and comments on the windows backs, or displaying application dialogs without risking them being detached from the application they relate to.

All windows start by looking like a normal 2D or 2.5D window, but can be manipulated as thin slate-like 3D objects which can be set at any angle or turned completely around by the user.

Other features include provision of a panning virtual desktop, icons that reflect the live status of the window they represent and zooming of a window when it receives focus.

Le Petit Poucet is free software to display and edit GPS routes and tracks in a 3D scene. The aim of Le Petit Poucet is to build the scene around the GPS data and 2D maps or 3D terrain models.
Apart from being techies, we are outdoor sport lovers and want to prepare our outings and show them to our friends and families. We hope you will find Le Petit Poucet useful. The objective statement being laid, here is the reality and roadmap.
Current version is a pre-alpha version numbered 0.0.2, it is dedicated to David Thompson a great explorer of western Canada. He is been surveying the wild land for 28 years and he is the first person to complete a survey of the Columbia River.
Le Petit Poucet is now able to read a lot of GPS file formats and to connect to the GPS receivers thanks to GPSBabel. It is also able to mix coordinate systems in projected or earth centric referentials.
Currently. Le Petit Poucet is called from the terminal, see command line manual or type the -h or --help option to get the command line usage. We hope to provide quickly a graphical user interface. The program has been compiled and run on Linux (Intel) and Mac Os X (v 10.3), it should work on many other platforms as the core libraries (Open Scene Graph, GPSBabel and GDAL) are portable.
Main features:
Main features
- Loading of tracks or routes, independent waypoints and maps or terrain models and display them on a 3D scene.
- Support of many GPS data file formats through GPSBabel or custom parsers.
- Download GPS receiver data via Serial or USB port.
- 3D navigation based on continuous zoom, swivel and pan with excellent real time anti-aliasing.
- Mixing of several coordinate systems (e.g.: geocentric and projected, UTM and Lambert).
- Coordinate system selection from command line.
Tracks
- Tracks are shown as a set of track segments. Track segments are sets of waypoints connected with a line.
- Track segments are not connected but share the same color and input coordinate system.
- Multiple tracks are shown in a viewer, track color is automatically chosen to visually distinguish tracks.
Waypoints
- Waypoints are displayed as a 3D symbol plus a text in case of named waypoint.
- Name text is automatically oriented toward screen and font size is adjusted dynamically too.
- Text color is selected from command line
- Waypoint information (location, elevation and time) is displayed in a head up display (HUD) when mouse flies over the point.
- Waypoint symbol is loaded from file
- Feature points, i.e. point out of a track, are selected. Are shown only the ones that are in the area of the displayed maps and tracks.
Maps
- 2D Maps are displayed in 3D perspective with box subtrat.PC
- Map loading is currently only supported for the Carte Sur Table file format.
- Map elevation in the 3D scene is computed based on the minimum elevation of the loaded tracks to reduce perspective effects.
- For tracks without maps a box is displayed below the track to improve perspective.
- In the current version, loading of 3D terrain model is through Open Scene Graph (OSG). Models must be projected and optimized using OSG utilities like osgdem see Loading Blue Marble.
Enhancements:
- All the features of release 0.0.5 are now accessible from menus and dialog boxes.
- A graphical user interface is used to wrap the main functionality of the track viewer in 3D, such as opening and closing files; focusing and zooming on tracks, waypoints, or segments; and generating terrains from downloaded or local imagery.

JOpenChart provides a Java library and toolkit for generating and embedding charts into applications.
JOpenChart is a free Java Toolkit and library for embedding charts into different kinds of applications, no matter if they are server side, desktop or web applications. Commercial solutions are pretty expensive and at the time I started working on JOpenChart, there was no satisfying open source solution available.
Currently, the library provides all the functionality to draw different kinds of charts, like line, bar, pie and plot charts. Additionally, the class structure includes the necessary classes for the encapsulation of sets of data and the classes for all parts of a typical chart, like a coordinate system, coordinate axes, legends, title and chart renderers.
I put great effort into a good design, ie understandable, logical class structures, elegant interfaces, use of abstract classes etc. The library is easily extendable to provide your own functionalities. This is best illustrated by noting, that all the Renderer classes, which paint the charts, have about 150 - 200 lines of code.
Furthermore, a few more or less proof-of-concept classes are finished that demonstrate how to embed charts into web applications or Swing applications using Servlets or a JComponent respectively.
Main features:
- rendering of pie charts, line charts, bar charts and plot charts
- easy extensibility using a simple Renderer interface API
- linear and logarithmic y-axis
- different data model classes for implementing numerical data sets, data sets with non-numerical x-axis values, dynamic data sets for displaying incoming measured data, SQL database query results.
- polynomial and spline interpolation of data sets and linear regression of measured data
- binding data sets to one of two y-axes with different scales
- plotting of mathematical functions given as String parameters
- exporting diagrams as image files at least using PNG or JPEG compression and whatever encoding the Java Advanced Imaging Library supports
- Servlet Toolkit for the easy inclusion of charts into web applications
- Swing components to integrate charts in Swing applications
Enhancements:
- Now renders stacked bar charts and radar charts.
- Fully automatic, and good looking, margin adaption. No more cut-off labels.
- Add data models with differently sized data sets.
- Support for editable data models, enabling real time updated GUI charts, see GraphFrame.java as an example and the TestGUI ant target.
- Now allows manually setting of maximum and minimum x- and y-values, allowing for zooming.
- JDBCPlotter.java allows plotting of SQL query results.
- Various options for controlling rendering style, esp. of bar charts and coordinate systems, see FunctionPlotApplet.java and always TestChart.java.
- e.g Setting the axis units
- and displaying sums on top of bars etc.
- Choose preset shapes and arbitrary colors for your data sets and plot charts, easily implement your own shapes
- RowColorModel is not a singleton instance anymore
- I externalized the ChartDataModelConstraints class, you can provide your own implementation or extend the existing ones. See StackedChartDataModelConstraints as an example.
- Web archive (war file) now supports Tomcat 3.x and 4.x.
