[Programming] Object-Oriented Graphics Rendering Engine


Object-Oriented Graphics Rendering Engine (OGRE)

OGRE is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce applications utilising hardware-accelerated 3D graphics. The class library abstracts all the details of using the underlying system libraries like Direct3D and OpenGL and provides an interface based on world objects and other intuitive classes.

I always thought that OGRE is one of the game engines and wanted to use it to get going with game development………..but when I visited it’s site I found a question followed by it’s explanation:

Is OGRE A Game Engine?

No. OGRE can be (and indeed has been) used to make games, but OGRE is deliberately designed to provide just a world-class graphics solution; for other features like sound, networking, AI, collision, physics etc, you will need to integrate it with other libraries, something several frameworks have done, and we have a collision / physics reference integration library as an example in our distribution.

Why? Well, one reason is that not everyone who needs a 3D engine wants to make games, so we don’t assume that you do – you can use OGRE for games, simulations, business applications, anything at all. Secondly, even within the games industry, requirements can vary widely; for example a MMORPG will need a very different kind of network library than an FPS, and a flight sim will need a different kind of collision / physics system to fighting game. If OGRE included all these features, we would be enforcing a particular set of libraries on you, with an inbuilt set of assumed requirements, and that’s not good design. Instead, we provide a very integration friendly API and let YOU choose the other libraries, if you want them. Many experienced game developers have expressed their approval of this approach, because there are no inbuilt constraints. It can be more daunting for newer users who just want to build another FPS-style game, but for those people there are a growing number of existing frameworks using OGRE which provide a complete solution using a given combo of libraries; but it’s important to realise that OGRE itself will always remain separate, flexible enough to be incorporated into any of these. The principle is of collaboration and integration with other libraries, rather than assimilation of them, a standard tenet of component-based design.

Not bad though…………. atleast it is a start, it will make me understand the basic functionalities of graphical operations in GAMES 🙂

GameDev conducted an interview of Steve Streeting, the project lead and original developer of OGRE, where he unveils how and why he started  to code OGRE. A nice interview for the starters like me 🙂
