Game Blender
From Wikipedia, the free encyclopedia
Game Blender is a sub-application of Blender, the popular open source 3D application, used to make games using Blender. The Game Engine was written from scratch in C++, including support for features like Python scripting and OpenAL 3D sound. Blender being programmed in C and Game Blender in C++ kept development strictly separated.

[edit] History
Erwin Coumans and Gino van den Bergen developed Game Blender in 2000. The goal was to make a saleable commercial product that users of the freeware Blender could use to create games and real-time presentations. These games could either run as stand-alone applications or embedded in a web page; using a special plugin created from the Game Blender sources. An alpha version of the Internet Explorer browser plugin is on preview, and Firefox and COLLADA support is under consideration. Game Blender is used by inserting logic bricks (a combination of "sensors", "controllers" and "actuators") to control the movement and display of objects in the engine. Game Blender is also able to be extended via the Python programming language. Game Blender is bundled with Blender 3D which can be downloaded freely from Blender's official website, http://www.blender.org/.
Blender was primarily authored by Ton Roosendaal, who worked for Not a Number Technologies (NaN). NaN went bankrupt in 2001, however, the creditors agreed to release Blender under the terms of the GNU General Public License, for a one-time payment of €100,000 (approximately US$147,000 as of January 2008; approximately equal to the amount in euros at the time). On July 18, 2002, a Blender funding campaign was started by Roosendaal in order to collect donations and on September 7, 2002 it was announced that enough funds had been collected and that the Blender source code would be released. Blender is now an open source program being actively developed under the supervision of the Blender Foundation.
After version 2.37a was released, the game engine was almost completely stable again, but it wasn't until version 2.41 that a complete and stable version of the Blender game engine was released. Currently, a team is working on developing Blender, releasing many new additions and changes periodically. Version 2.42 shows even more additional features being implemented into the game engine, including integration of the Bullet Rigid Body Dynamics and Vehicle Physics.
[edit] GameBlender
Release version 2.41 of Blender showcased a version that was almost entirely devoted to the game engine. Audio is now fully supported whereas previous versions did not. A new system for integration of GLSL shaders has been added to help bring GameBlender back in line with modern games.
Game Blender is intended to reach a broad community and work on as many platforms as Blender 3D currently supports. It achieves this by using OpenGL, a cross-platform graphics layer.
Game Blender layout is simple and easy to use, and easy for non-programmers to learn creation of simple games. Larger and more complex games requires knowledge of the Python programming language in order to simplify tasks. GameBlender has a full Python implementation, allowing game programmers to use Python in order to program their games.
The GameBlender uses a system of logic bricks with link lines to develop logic within a game. This allows non-programmers to click and drag logic into their game. These logic bricks are highly adaptable and can be used for such purposes as implementing a Python script.
The latest version of game blender is 4.5
[edit] Game Blender Future
Current development in Game Blender is focused on the new Bullet physics engine in an attempt to make it faster and more life like with better collision detection and object interaction. A car physics engine is also added in version 2.42 that makes it easy to create cars and subsequently, racing games. The process of modifying cars has been simplified, leading to a more realistic feel and better customization of individual cars.
