Free 3d engine software for linux

Drome Engine is a 3D game engine thats written in C++ and uses OpenGL for graphics rendering. Its currently under constant development; the main focus at this time is to improve and stabilize the application programming interface (API).

Fuzz Engine is an SDL/Mono-based 2D game engine that loads its games from XML so that anyone with a simple text editor can produce their own high-performance games in minutes.

Known problems: the platform game system is still pretty flaky.

Nelit2 Engine project is a game engine.
Nelit2 Engine is a game engine that uses a Model-View-Controller concept. All View-s classes was developed by me, and you can dont worrie about this.
Model-s classes also was developed by me, but you can modify it for your game or write new class and use Model class how abstract.
The engine uses some popular libraries such OpenGL and SDL.
It works on Unix systems and on Windows.
Enhancements:
- Decoding png, bmp, jpg texture-file.
- 3D mesh.
- Cubemap texturing.

The Irrlicht Engine is an open source high performance realtime 3D engine written and usable in C++ and also available for .NET languages.
Irrlicht Engine is completely cross-platform, using D3D, OpenGL and its own software renderer, and has all of the state-of-the-art features which can be found in commercial 3d engines.
Weve got a huge active community, and there are lots of projects in development that use the engine.
You can find enhancements for Irrlicht all over the web, like alternative terrain renderers, portal renderers, exporters, world layers, tutorials, editors, language bindings for java, perl, ruby, basic, python, lua, and so on. And best of all: Its completely free.
Main features:
- High performance realtime 3D rendering using Direct3D and OpenGL [more]
- Platform independent. Runs on Windows95, 98, NT, 2000, XP and Linux.[more]
- Huge built-in and extensible material library with vertex and pixel shader support [more].
- Seamless indoor and outdoor mixing through highly customizeable scene mangagment. [more]
- Character animation system with skeletal and morph target animation. [more]
- Particle effects, billboards, light maps, environment mapping, stencil buffer shadows, and lots of other special effects. [more]
- .NET language binding which makes the engine available to all .NET languages like C#, VisualBasic, and Delphi.NET.
- Platform and driver independent fast software renderer included. It features z-buffer, gouraud shading, alpha-blending and transparency, fast 2D drawing.
- Powerful, customizeable and easy to use 2D GUI System with Buttons, Lists, Edit boxes, ..
- 2D drawing functions like alpha blending, color key based blitting, font drawing and mixing 3D with 2D graphics.
- Clean, easy to understand and well documentated API with lots of examples and tutorials.
- Written in pure C++ and totally object orientated.
- Direct import of common mesh file formats: Maya (.obj), 3DStudio (.3ds), COLLADA (.dae), DeleD (.dmf), Milkshape (.ms3d), Quake 3 levels (.bsp), Quake2 models (.md2), Microsoft DirectX (.X)... [more]
- Direct import of Textures: Windows Bitmap (.bmp), Portable Network Graphics (.png), Adobe Photoshop (.psd), JPEG File Interchange Format (.jpg), Truevision Targa (.tga), ZSoft Painbrush (.pcx)... [more]
- Fast and easy collision detection and response.
- Optimized fast 3D math and container template libraries.
- Directly reading from (compressed) archives. (.zip)
- Integrated fast XML parser.
- Unicode support for easy localisation.
- Works with Microsofts VisualStudio6.0?, VisualStudio.NET 7.0-8.0?, Metrowerks Codewarrior, and Bloodshed Dev-C++ with g++3.2-4.0.
- The engine is open source and totally free. You can debug it, fix bugs and even change things you do not like. And you do not have to publish your changes: The engine is licensed under the zlib licence, not the GPL or the LGPL.

Natrium Engine project tracks groups of parts by letting users define the relationships between parts. Users create definitions for configurations and parts.

These are joined together to form a rule for parts in configurations. When a part is removed from or added to a configuration, all children of that part are also transferred. This has special applications to "living" inventory, or groups of disparate parts that need to be tracked as a group rather than individually.

For example, if a carburetor is made a separate configuration from an engine, then when removing it all parts associated with the carburetor are also removed. A facility is provided for tracking user-defined line-item costs of each part.

The GTK-Qt Theme Engine is a project allowing GTK to use Qt widget styles.
Gtk-Qt Theme Engine behaves like a normal GTK theme engine, but calls functions from Qt instead of doing the drawing itself.
Version restrictions:
- Due to an incompatibility between Qt and the GNOME window manager, some parts of GNOME will not be themed by Qt.
- The theme will run fine under GNOME, but the logout box and window border menus will appear blank.
- It appears that the only way to overcome this bug is by patching Qt itself.

Kyra Sprite Engine project is a C++ sprite engine built on SDL.
Kyra is a simple, fully featured Sprite engine written in C++. The Kyra engine is suited to 2D, isometric, and quasi-3D games.
It is built on top of SDL for cross platform use. It supports tiles, sprites, and user drawn surfaces.
It has full support for alpha blending, scaling, color transformation, pixel perfect collision detection, OpenGL acceleration, and mouse testing.
It comes with tools to define sprites and import images into the system.
Enhancements:
- Update Kyra to work with the new SDL 1.2.11
- Fixed 64 bit support for Kyra.
