Free vrml and x3d software for linux

Relax and Recover (abbreviated rear) is a highly modular disaster recovery framework for GNU/Linux based systems.
The disaster recovery information (and maybe the backups) can be stored via the network, local on hard disks or USB devices, DVD/CD-R, tape, etc. The result is also a bootable image that is capable of booting via PXE, DVD/CD and tape (OBDR).
Main features:
- Focus on Disaster Recovery
- Modular concept
- For Linux and other Unix-like operations systems
- No external dependancies - use only standard software supplied with the distribution
- encryption (optional) - openssl ?
- Linux: kernel > 2.6 supported (no kernel 2.2/2.4 support !)
- User friendly - minimal output, use log file for error messages and details
The aim is to make rear as least demanding as possible, it will require only the applications neccessary to fulfill the job rear is configured for. All other applications will be copied to the rescue system if they are present.

BRL-CAD project is a powerful Constructive Solid Geometry (CSG) solid modeling system. BRL-CAD includes an interactive geometry editor, ray tracing support for rendering and geometric analysis, network distributed framebuffer support, image-processing and signal-processing tools. The entire package is distributed in source code form.
Since the late 1950s, computers have been used to assist with the design and study of combat vehicle systems. The result has been a reduction in the amount of time and money required to take a system from the drawing board to full-scale production as well as increased efficiency in testing and evaluation.
In 1979, the U.S. Army Ballistic Research Laboratory (BRL) (now the U.S. Army Research Laboratory [ARL]) expressed a need for tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no existing computer-aided design (CAD) package was found to be adequate for this purpose, BRL software developers began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD.
Now comprising over one-half million lines of C code, BRL-CAD has become a powerful constructive solid geometry (CSG) modeling package that has been licensed at over 2,000 sites throughout the world. It contains a large collection of tools, utilities, and libraries including an interactive geometry editor, raytracing and generic framebuffer libraries, a network-distributed image-processing and signal-processing capability, and a customizable embedded scripting language. In addition, BRL-CAD simultaneously supports dual interaction methods, one using a command line and one using a graphical user interface (GUI).
A particular strength of the package lies in its ability to build and analyze realistic models of complex objects using a relatively small set of "primitive shapes." To do this, the shapes are manipulated by employing the basic Boolean operations of union, subtraction, and intersection. Another strength of the package is the speed of its raytracer, which is one of the fastest in existence. Finally, BRL-CAD users can accurately model objects on scales ranging from the subatomic through the galactic and get "all the details, all the time."
The application side of BRL-CAD also offers a number of tools and utilities. They primarily concern (1) geometric conversion, (2) geometric interrogation, (3) image format conversion, and (4) command-line-oriented image manipulation. The following is a list of the major BRL-CAD tools and utilities.
- MGED (Multiple-Device Geometry Editor) ? BRL-CADs graphics editor. (For detailed guidance on the use of MGED as well as a list of all the MGED commands currently available, see Butler et al. [2001].)
- Tools for raytracing and interrogating raytraced geometric objects.
- rt ? the main raytracer for rendering images in BRL-CAD.
- nirt ? a package for firing rays interactively and getting information about what the rays run into.
- remrt ? a network-distributed raytracing package.
- An assortment of geometric converters to convert to and/or from other geometry formats, including Euclid, ACAD, AutoCAD DXF, TANKILL, Wavefront OBJ, Pro/ENGINEER, JACK (the human factors model for doing workload/usability studies), Viewpoint Data Lab, NASTRAN, Digital Equipments Object File Format (OFF), Virtual Reality Mark-up Language (VRML), Stereo Lithography (STL), Cyberware Digitizer data, and FASTGEN4.
- bwish ? a Tcl/Tk interpreter in a windowing shell with enhancements compiled into it for accessing BRL-CAD libraries. It also includes various other extensions to the Tcl language.
- irprep ? produces input to the PRISM (Physically Realistic Infrared Simulation Model) code.
- JOVE (Jonathans Own Version of Emacs) ? a fast, light implementation of Emacs.
- Applications for displaying images of various types on the framebuffer application and retrieving data from that framebuffer into images of various types.
- Tools for generating geometry for common objects such as fences, walls, and geometric mathematical oddities (e.g., the sphereflake shown in Figure 2 in Section 4).
- Data manipulation programs to (1) convert integers to floats, floats to doubles, etc. (e.g., cv); (2) perform mathematical operations on file elements (e.g., imod, umod, and dmod); (3) compute statistics of file elements (e.g., istat, ustat, and dstat); etc.
- Utilities for building animation scripts ? keeping track of columnar data and interpolating it to allow one to produce input to the rt program to render multiple items for animation.
- Utah Raster Tool Kit ? image manipulation of all RLE-based images.
- Programs for manipulating images and converting between different image file types. The two primary BRL-CAD types are pix (24-bit red, green, and blue [RGB] color images) and bw (8-bit greyscale images). Converters exist for various image formats including alias, png, ppm, etc.
- Programs for filtering images, doing histograms on the image data, and extracting rectangles from the images.
- Tools for combining two images and blending them together. (These tools were created before good image editing tools for video production were available; today users would typically load the images directly into a video editing package.)

MiniUPnP Client and Daemon is an UPnP IGD client lightweight library and UPnP IGD daemon.
The UPnP protocol is supported by most home adsl/cable routers and Windows 2K/XP. The aim of the MiniUpnp project is to bring a free software solution to support the "Internet Gateway Device" part of the protocol.
The Linux SDK for UPnP devices (libupnp) seems too heavy for me. I want the simplest library possible, with the smallest footprint and no dependencies to other libraries such as XML parsers or HTTP implementations. All the code is pure ANSI C.
Compiled on a x86 PC, the miniupnp client library have less than 15KB code size. For instance, the upnpc sample program is around 20KB.
The project is divided in two main parts : the client library, enabling applications to access the services provided by an UPnP "Internet Gateway Device" present on the network, and the miniupnpd daemon, providing these services to your network from a linux or bsd box being the gateway. At the moment the miniupnpd is developped on OpenBSD 3.0+ with pf. You can see some of the work I have done to integrate with pf on this page.
As pf is also available under FreeBSD, guys at the pfSense project have ported miniupnpd to this system.
For some reasons, it may be not the good solution for you to use the code from the MiniUPnP project directly.
As the code is small and simple to understand, it is a good base to take inspiration for your own UPnP implementation. The KTorrent team UPnP plugin in C++ is a good example.
If you are wondering which home router is working with the miniupnp client, you can find the answer here. In fact, you are more likely to help me fill the list by sending me an email.
Usefulness of the miniUPnP client library
The usage of the miniUPnP client library is useful whenever an application needs to listen for incoming connections.
Examples : P2P applications, FTP clients for active mode, IRC (for DCC) or IM applications, network games, any server.
The typical usage of UPnP capabilities of a router is a file tranfert using MSN messenger. The MSN Messenger software uses the UPnP API of Windows XP to open port for incoming connection. To mimic the MS software, it is a good idea to use UPnP as well.
Enhancements:
- This release adds changes to accommodate the Linux 2.6.22 kernel.

Search And Rescue project is an air rescue flight simulator. The player pilots rescue helicopters to rescue victims in various situations of distress.

Search and Rescue is a helicopter based air rescue flight simulator. It employs a simple flight dynamics engine that is targetted towards the "average" player. It is not designed to be a cutting-edge realistic simulator, but rather a flexable game that everyone can play and enjoy.

The history of the development of this game goes back to 1997, when Search and Rescue was created as an explorative to design for more complex 3D games using the OpenGL graphics library. Much of the effort in the development of this game came from Wolfpack Entertainment and many dedicated contributors (see credits below).

This game was ported to Windows early on in its development to ensure the portability of its graphics code. However the Win32 version lacked certain features due to differences in Windows design of its graphic, sound, and controller implementation.

The flight dynamics engine (FDE) features helicopter, aircraft, and tilt-rotor aircraft flight dynamics models (FDMs). It uses source-centered (as opposed to world-centered) mathimatical equations to simulate movement which mimicks but does not fundimentally follow standard physics equations. This simplifies the "flyability" of the aircrafts at a slight cost of realisim and lightens processor load.

The 3D visual models of the aircrafts and objects were created by a program called Vertex 3D, an OpenGL modeller designed to create 3D visual models that are optimized for OpenGL.

Each scene is a finite sized flat world, separated vertically by cloud layer(s) and centered at the origin with an artificial longitude and latitude offset applied to displayed positions.
