Writing a game rendering engine architecture

Meeting that goal required keeping the technology quite general-purpose, writing clean code, and designing the engine to be very extensible. The early plans to design an extensible multi-generational engine happened to give us a great advantage in licensing the technology as it reached completion. After we did a couple of licensing deals, we realised it was a legitimate business.

Purpose[ edit ] In many cases game engines provide a suite of visual development tools in addition to reusable software components. These tools are generally provided in an integrated development environment to enable simplified, rapid development of games in a data-driven manner. Game engine developers attempt to "pre-invent the wheel" by developing robust software suites which include many elements a game developer may need to build a game.

Most game engine suites provide facilities that ease development, such as graphics, sound, physics and AI functions. These game engines are sometimes called " middleware " because, as with the business sense of the term, they provide a flexible and reusable software platform which provides all the core functionality needed, right out of the box, to develop a game application while reducing costs, complexities, and time-to-market — all critical factors in the highly competitive video game industry.

Often, game engines are designed with a component-based architecture that allows specific systems in the engine to be replaced or extended with more specialized and often more expensive game middleware components.

Some game engines are designed as a series of loosely connected game middleware components that can be selectively combined to create a custom engine, instead of the more common approach of extending or customizing a flexible integrated product. However extensibility is achieved, it remains a high priority for game engines due to the wide variety of uses for which they are applied.

Despite the specificity of the name, game engines are often used for other kinds of interactive applications with real-time graphical needs such as marketing demos, architectural visualizations, training simulations, and modeling environments.

These engines rely upon the game developer to implement the rest of this functionality or assemble it from other game middleware components.


These types of engines are generally referred to as a "graphics engine", "rendering engine", or "3D engine" instead of the more encompassing term "game engine". This terminology is inconsistently used as many full-featured 3D game engines are referred to simply as "3D engines".

A few examples of graphics engines are: As technology ages, the components of an engine may become outdated or insufficient for the requirements of a given project.

Since the complexity of programming an entirely new engine may result in unwanted delays or necessitate that the project be completely restarteda development team may elect to update their existing engine with newer functionality or components.

Main game program[ edit ] The actual game logic has to be implemented by some algorithms. It is distinct from any rendering, sound or input work.

Rendering engine[ edit ] The rendering engine generates animated 3D graphics by any of a number of methods rasterizationray-tracing etc. Low-level libraries such as DirectXSimple DirectMedia Layer SDLand OpenGL are also commonly used in games as they provide hardware-independent access to other computer hardware such as input devices mouse, keyboard, and joysticknetwork cards, and sound cards.

Before hardware-accelerated 3D graphics, software renderers had been used. Software rendering is still used in some modeling tools or for still-rendered images when visual accuracy is valued over real-time performance frames-per-second or when the computer hardware does not meet needs such as shader support.

With the advent of hardware accelerated physics processing, various physics APIs such as PAL and the physics extensions of COLLADA became available to provide a software abstraction of the physics processing unit of different middleware providers and console platforms.Customer reviews of Game Engine Architecture can be found at urbanagricultureinitiative.com, urbanagricultureinitiative.com and urbanagricultureinitiative.com GEA cites the OGRE rendering engine as a great example of how various engine systems can be designed and implemented, and I'm proud to report that GEA was featured on the OGRE web site.

Singleton Game Programming Patterns Design Patterns Revisited. This chapter is an anomaly. Every other chapter in this book shows you how to use a design pattern. This chapter shows you how not to use one.. Despite noble intentions, the Singleton pattern described by the Gang of Four usually does more harm than good.

They stress that the pattern should be used sparingly, but that message was.
