Ogre3D kib

For those interested in OpenGL for games...

you might want to check out Ogre3D library.

http://www.ogre3d.org

Its cross platform. On Windows supports both
DirectX and OpenGL acceleration of 3D rendering.

For a person starting out Blender might be a good place inbuilt game engine.

Problem on vista it is opengl completely right down to the interface.

Crystalspace is developing a Blender link. So Opengl limitation will not be a problem.

www.blender.org and crystal.sf.net. Good starting points. Find you self a good C++ or tutorial You will be needing it in time. A great C book would not hurt either.

Advantage over Orge blender has internal scripting and internal game development

Quake III needs OpenGL, so there's no point in this discussion. ReactOS MUST include OpenGL Support :o)

As far as i know, the Windows version of SDL is only a wrapper around DirectX. Even if it weren't that way, it still wouldn't help us much to get DirectX games running on ReactOS, which is the target, after all.

yup, this is exactly the way it is.... since SDL is just a wrapper around D3D/GDI.

please folks, lets have this discussion straight, game engines like ogre are really not part of the topic.

ontopic: i think adding true opengl support is not that much of a problem, it allready works somewhat, and advancing it will not be that hard, since 99% of the work is done by the vendors driver.

in addition things like DInput and DSound are already present to a big extent IIRC, the only really demanding thing will be D3D + D3DX (especially D3DX since it mostly consists of driver-independent helper-functions).

but i am looking forward to progress in D3D/D3DX and believe in the wonders the developers here are abled to do
:D

SDL Default under windows its a Wrapper around Direct X. It can be forced to wrap around Opengl instead.

Note the Default can be changed if required.

Opengl extended apps play better with Opengl SDL than Direct X SDL.

Just because a game or something is built under SDL and is running on windows does not mean that is using Direct X. Just normally means its using Direct X.
