NAUSEA is a programmable distributed 3D world simulator engine.

The most important feature of NAUSEA is its programmability: every aspect of
the world *behaviour* implemented in the server can be programmed by the
(the "world superuser") in Scheme, using an event-based model.

The world status is kept in a central server communicating with (possibly)
multiple clients over TCP/IP sockets.

Clients can be either interactive or non-interactive: interactive clients
forward user commands to the server and provide graphic interface.
Non-interactive clients are used to implement artificial intelligence in
non-player characters.
Interactive clients also provide a quite elaborate 2D interface, and support
for music and sound.

A powerful editor with graphic interface allows to edit both the world data,
including object placement, and the world metadata, cosisting in the
of objects.

Some relatively simple utilities to manage archives and models are also

The system is thought as a very high-level framework to build elaborate
or simulations.

The code is heavily object-oriented, and quite clean.

The Scheme engine is Guile. We interface with it from C++ using a relatively
simple higher-level wrapper, which in particular makes easy to define smobs.

Interactive clients have an interface built on SDL (plus SDL_image and
SDL_mixer) and OpenGL. The editor uses Qt and OpenGL.

The C++ code is quite heavily optimized, even if some opportunities for more
speed remain to be exploited.

The code is very portable, independent from either processor word length
and byte ordering. NAUSEA is written to run on GNU systems, currently
GNU/Linux, and in the future (we hope) GNU/Hurd. NAUSEA should be very
easy to port to other systems, but we don't consider them prioritary.


NAUSEA is still in flux at the time of this writing (2005-10-13), but mostly
usable. The code consists of about 40,000 (non-empty, not automatically
generated) lines, the vast majority of which is C++. The rest is Scheme.

The editor interface is being heavily reworked, some optimizations are
and there is need for documentation, especially about the Scheme interface.
Non-interactive clients don't actually exist yet.

Other Software Required:
  Well, maybe the only not-so-common item is glpng:
- GNU Guile >=1.6, GNU MP, GNU Readline (Readline is optional)
- GNU Texinfo, a TeX distribution (TeX is optional)
- An OpenGL implementation, glpng
- SDL, SDL_image, SDL_mixer
- Qt 3.3.x
- GNU Bison, flex
- GCC, GNU binutils, GNU Make

Other Comments:
  I, Luca Saiu, am co-author of the project.
The other co-author is Dario Russo, who has an account on Savannah with login
name "darior".
