OverviewThe
design of True3D*Shell is inspired to multiverse and bubble universe cosmological
theories were the universe is an expanding cosmic bubble and this bubble creates
a new bubble which produces it the others. True3D*Shell
is an open source 3D desktop environment that allows users to experience 3D browsing
in a virtual reality universe where information are organized in 'bubbles' connected
by 'pipes'. Bubble can be the equivalent of a folder in a computer, a shared folder
in a network, or an execution space for a 3D program. Bubbles generated by different
computers are connected by "pipes" acting as network connections, providing
network transparency. True3D*Shell
integrates in itself the following concepts: Shell
: provides access to the kernel servicesDesktop
environment : offers a graphical user interface (GUI) solution to operate
a computerAvatar : provides a fantastic
representations of a person's self with witch user can explore the virtual universe.
Virtual Reality : users can interact with
a virtual environment either through the use of standard input devices such as
a keyboard and mouse, or through multimodal devices.MVC
paradigm : is a software architecture that separates an application's data
model, user interface, and control logic into three distinct components.Multithreading
: Threads are a way for a program to split itself into two or more simultaneously
running tasks. Multiple threads can be executed in parallel on many computer systems.
Grid computing : provides the ability to
perform higher throughput computing by taking advantage of many networked computers
to model a virtual computer architecture that is able to distribute process execution
across a parallel infrastructure. MOM paradigms
: Message Oriented Middleware is a category of inter-application communication
software that relies on asynchronous message.Multiverse
theory: a multiverse (or meta-universe) is the hypothetical set of multiple
possible universes (including our universe) that together comprise all of physical
reality. The structure of the multiverse, the nature of each universe within it
and the relationship between the various constituent universes, depend on the
specific multiverse hypothesis considered.Bubble
theory: is a posits an infinite number of open multiverses, each with different
physical constants. The bubble universe model is a variant of the inflationary
model of the big bang. The formation of our universe from a "bubble"
of a multiverse was proposed by Andre
Linde. This Bubble universe theory fits well with the widely accepted theory
of inflation.True3D*Shell allows to create several interconnected
universes across a network: Software
architectureFrom architectural point of view, True3D*Shell is
based on the following technologies:Intel IA32 or IA64 hardware platformsLinux
or Windows O.S. platformsPOSIX or WIN32 SDKTCP/IP Socket2 libraryOpenGL:
is a specification defining a cross-language cross-platform API for writing applications
that produce 3D computer graphics.FreeGLUT:
is a library of utilities for OpenGL programs, which primarily perform system-level
I/O with the host operating system.MQ4CPP:
is an open source toolkit implementing an enterprise messaging system, also referred
to as message-oriented middleware (MOM).LIB3DS:
toolkit for handling 3DS files. DOTCONF++:
toolkit for handling configuration file. True3D*Shell
is compiled and tested on the following platforms: Windows 2000
(x86) Windows XP (x86) Windows 2003 Enterprise
Server SP1 (SMP Itanium2) Linux Red Hat ES 3.0 (x86 - kernel
2.4.21) Linux SuSE SLES 8 (SMP Itanium2 - kernel 2.4.21) Linux
Red Hat ES 3.0 (SMP Itanium2 - kernel 2.4.21) Linux Red Hat ES

Development tools
To develop this project I have used the following
free tools:Java
SDK 1.4.2: to run EclipseEclipse
3.0: for visual editing.Eclipse
CDT 2.0 plug-in: for C and C++ editing.Microsoft
Visual C++ Express 2005: include Intel x86 compiler, linker and standard C
and C++ libraries.Microsoft
Platform SDK (Core SDK only): include Intel Itanium2 compiler and Windows
SDK libraries. Milkshape

binaries are usually included in OS distribution.FreeGLUT:
OpenGL Utility Toolkit, a window system independent toolkit for writing OpenGL
programs.MQ4CPP: middleware implementing
distribuited messaging between threads.lib3ds:
free ANSI-C library for working with the popular "3ds" 3D model format.dotconf++:
dotconf like configuration file parser written in C++. DownloadTrue3D*Shell

Release
Source code Release
notes 1.0Nightbuild_V0.12This
version is only a proof of concept.1.13DSHELL_V1.1.ZIPIn
this release the product allows only to browse the local file system and uses
OpenGLUT. 1.23DSHELL_V1.2.ZIPIn
this release user can browse local file system and run selected file, browse remote
file system and download/run selected file, run a robot that automatically browse
local and remote file system. Now the project include FreeGLUT.1.33DSHELL_V1.3.ZIPThis
release integrates DOTCONFPP project to handle configuration files and LIB3DS
project to handle Autodesk files.Meshes are separated from the engine and
loaded during startup from .3DS files with texture in .BMP 24 bit RGB format.
User can now fully customize this product through a configuration file and use
different configuration file using -f option at startup.1.43DSHELL_V1.4.ZIPThis
release implements a new internal architecture and allows a user to switch between
universes in the same session. It is still incomplete in some functionality. It
requires MQ4CPP version
1.16 or upper. Precompiled
binaries for True3D*Shell
