what is the difference between OpenGl and DX anyway? i have heard comments like OpenGL has better graphics but DirectX is faster, is this true?

OpenGL is also cross-platform, whereas DirectX is Windows only. This may not be a problem if you're only writing code for Windows, but it's quite important to us Linux users...

OpenGL has gluLookAt.

For the record: I endorse OpenGL and not using DX.

[syntax="c++"]
public: static Matrix LookAtLH(
Vector3 cameraPosition,
Vector3 cameraTarget,
Vector3 cameraUpVector
);

public: static Matrix LookAtRH(
Vector3 cameraPosition,
Vector3 cameraTarget,
Vector3 cameraUpVector
);
[/syntax]

lol... I didn't say that is why I endorse OGL. When it comes down to it DX and OGL don't perform much different. The key differences are that OpenGL is cross platform, DX is platform dependent, OpenGL can develop for the Game Cube, DX can develop for the X-Box. You should only need to learn DX if you need to develop for the X-Box wich most people aren't. I prefer OpenGL simply because of the syntax and the application of the API itself. Not to say that Direct X is difficult, but you have to do so much that it almost defeats the purpose of using an API to not reinvent the wheel.

so a game made with DX could just get burnt onto a DVD disk then placed into a xbox consol and it will work??

i understand this is getting really off topic, but you guys keep on interesting me.

[Bugdude]

No, but you could take your DX code and port it to the XBox with a lot less difficulty than porting OpenGL-based code.

[Samuel]

How would you port it? Do you just have to change keyboard and mouse messages to xbox messages? is this on msdn?

[Bugdude]

I would guess that development and porting instructions would be a part of the XBox development kit.

[Samuel]

were can i get the Xbox development kit from?

[tomcant]

Little bit o' googling...

Take a guess.

thanks for that link to google - lol

i think this one is a bit more precise
