Open GL and DirectX
« on: August 02, 2005, 01:29:57 pm »
Hi,

Could someone please describe what these are and how they differ?  Which should I choose?  Are they good for different things and situations?

Any info is appreciated.

Yours,
Aidan

Wikipedia is usually a good starting point

Thanks John,

It seems like a graphical 'Betamax vs VHS' situation for rendering.

cheers,
A

OpenGL and Directx are both graphics API's - in simple terms the program (maybe a game) talks to the API which then talks to the actual hardware of your graphics card.

Therefore graphics cards usually support standard API's such as OpenGL or DirectX.

DirectX actually does more than just graphics, as it supports sound, networking and other functions. It is a Microsoft standard and will be supported by all (current) Windows machines. Because of this many graphics cards are better supported for DirectX as the majority of computers run Windows.

OpenGL is arguably a more efficient, more complete (graphics) standard. It is non-proprietry. It will be found across many platforms eg Unix as well as Windows.

Neither standard should be taken as superior, however DirectX would be the natural choice for a Windows XP user as performance will normally be optimised for it.
