TA3D is a remake of Total Annihilations engine in full 3D with OpenGl&Allegro. Installing TA3D over Total Annihilation will port Total Annihilation to full 3D!!

TA3D loads maps,units,and more directly from Total Annihilation content. It adds some graphical effects like advanced particle effects for explosions,smoke,... and lots of things you would expect from a 3D engine.

K-3D is the free-as-in-freedom 3D modeling, animation, and rendering system for GNU / Linux, Posix, and Win32 operating systems. K-3D features a robust, object-oriented plugin architecture, designed to scale to the needs of professional artists, and is designed from-the-ground-up to generate motion-picture-quality animation using RenderMan-compliant render engines. We strongly recommend the Aqsis render engine for use with K-3D.
K-3Ds innovative interactive tutorial system will introduce you to basic use of the program. New tutorials can easily be recorded and shared with the rest of the community.
K-3D allows you to create and edit documents in multiple realtime OpenGL solid, shaded, texture-mapped views. You can even model, animate, and interact with animations while they play back for maximum productivity!
Main features:
- Camera: pan/tilt, zoom, dolly, modeling and tripod modes.
- Viewing Modes: Detailed selection of visible features.
- Hide / unhide geometry.
- Powerful scene graph procedual modeling with complete modeling history.
- Selection: Objects, meshes, faces, edges, patched, curves, point groups, point.
- Geometry types: Polygon, NURBS, subdivision, blobby.
- 3D Primitives: Cone, circle, cushion, cylinder, disk, grid, paraboloid, polyhedon, sphere, torus.
- Boolean modeling operations.
- Text: FreeType? support.
- Instantiation: Create duplicates without adding gemometry to the scene.
- Directed Acyclic Graph (DAG) allows arbitrary dataflow - any object property can be connected to any other compatible property.
- Animate any value.
- Unlimited number of animation channels.
- Bezier curve channels.
- Animate modeling operations.
- Textures with 16-bit float bitdepth.
- Procedual RenderMan shaders.
- Full RenderMan Support: Aqsis, Pixie, BMRT, PRman, 3Delight, Render Dot C.
- Extensible support for alternate render engines and models: YafRay.
- Render OpenGL previews to disk.
- Python engine (preferred for new script development).
- K3DScript engine (minimal scripting engine for tutorials / macros).
- JavaScript engine (legacy script engine).
- Support for alternate script engine plugins and environments.
- Basic 2D compositing.
- Bitdepth 16-bit float per channel.
- Geometry Formats: AC3D, ASCII Scene Export, Apple QuickDraw?3D, AutoCad, Ayam, DirectX?, GNU Triangulated Surfaces, Quake II, PDB, RenderMan Interface Bytestream, VRML, Wavefront ... (some of them depend on PLIB installation)
- Image Formats:
- JPEG (all platforms).
- PNG (all platforms).
- TIFF (all platforms).
- OpenEXR (requires optional OpenEXR plugin).
- BMP (requires optional ImageMagick? plugin).
- SUN (requires optional ImageMagick? plugin).
Enhancements:
- This release features major changes to the internal file-handling code to work correctly with files containing non-ASCII characters.
- Due to the sweeping changes needed to make this possible, this version is considered a "development" release, so users are encouraged to use this release for testing and feedback only.
- All users are strongly encouraged to upgrade to the 0.6 series of K-3D for its completely rewritten user interface, many new features, and significantly improved stability over 0.4.

libevent library provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached.
It is meant to replace the asynchronous event loop found in event-driven network servers.
libevent is meant to replace the event loop found in event driven network servers. An application just needs to call event_dispatch() and then add or remove events dynamically without having to change the event loop.
Currently, libevent supports /dev/poll, kqueue(2), select(2), poll(2) and epoll(4). It also has experimental support for real-time signals. The internal event mechanism is completely independent of the exposed event API, and a simple update of libevent can provide new functionality without having to redesign the applications. As a result, Libevent allows for portable application development and provides the most scalable event notification mechanism available on an operating system.
More information about event notification mechanisms for network servers can be found on Dan Kegels "The C10K problem" web page. Another library that abstracts asynchronous event notification is liboop.
Enhancements:
- Bugs in libevents HTTP layer were fixed.

Turtle3D project is a scheme implementation of the Turtle, in 3D.

It is object oriented, so you can have many turtles in the drawing window.

A test program is included.

Games::3D is a package containing an object system for (not only) 3D games.

SYNOPSIS

use Games::3D::World;

my $world = Games::3D::World->new();

$world->save_to_file( $filename );

my $loaded = Games::3D::world->load_from_file( $filename );

my $thing1 = $world->add ( Games::3D::Thingy->new( ... ) );
my $thing2 = $world->add ( Games::3D::Thingy->new( ... ) );

$world->link($thing1, $thing2);

Games::3D::World provides you with a container class that will contain every object in your game object system. This are primarily objects that have states, change these states and need to announce the states to other objects.

The Games::3D::World container also enables you to save and restore snapshots of your objects system.

Basic things that you object system contains are derived from a class called Games::3D::Thingy. These can represent physical objects (buttons, levers, doors, lights etc) as well as virtual objects (trigger, sensors, links, markers, sound sources etc).

You can link Thingys together, either directly or via Games::3D::Links. The links have some more features than direct linking, which are explained below.

This package also provides you with Games::3D::Sensor, a class for objects that sense state changes and act upon them. Or not, depending on the sensor. Sensors are primarily used to watch for certain conditions and then act when they are met. Examples are the death of an object, values that go below a certain threshold etc.

State changes are transported in the object system with signals.

Soya 3D is a high level 3D engine for Python. It relies on OpenGL, SDL and Cal3D. Soya 3D project is designed with games in mind, focusing both on performance and ease-of-use.
Soya 3D is available under the GPL and currently runs on GNU/Linux, though ports to other OS are planned (Mac OS X, windows,...) since it uses only portable libraries.
Main features:
- Multi-plateform : Linux / Unix, MacOSX, Windows
- Object model, including camera, light, world, volume,...
- Particle systems
- Fullscreen
- Tutorials and demos included
- Trees
- Raypicking
- Landscapes
- 3D character animation (with Cal3D)
- Exportation scripts for Blender, Obj/Mtl, Maya and 3DSmax
- Event management (keyboard, mouse,...)
- Cell-shading
- Shadows
- Environment mapping
Soya 0.6.1 and below were written in C and Python, but version 0.7 and higher are written in Pyrex and Python.
