OpenGL 3.0 etc

OpenGL 3.0 will offer features such as instanced rendering, stream out of vertex data to a buffer, texture buffer objects, numerous new texture formats and so on. Most importantly the Khronos Group is linking OpenGL and OpenGL ES, a mobile 3D graphics API via COLLADA and glFX, so what is supported in OpenGL 3.0 will see the light of the day in ES version as well.

Will Irrlicht move on onto OpenGL 3?

Why not? Ogl 3 might be ready in 2-3 years, I guess we'll have some time until then to implement it...
BTW: Most features will be available before, some are already available. It's much more a change of how things are implemented what makes the major difference. So maybe you won't see too much of this as Irrlicht covers much stuff under the hood.

Original story.

I still doubt that it will be relevant for the next years. DirectX10 compatible features are already exposed by a lot of OGL extensions by NVidia.

OpenGL 3 is about simplyfing and improving the API. its supposed to be easier and more effectively do things with OpenGL 3 code as compared to previous. DirectX 10, remember, has also gone under a similar simplification and atomization of functions

probably could speed things up a bit on the OpenGL driver by switching it to OpenGL 3 API. maybe some tests should be done once it is released?

Its pretty funny that your much more excited about this than DX10

Meh I reckon either is pointless right now, does Irrlicht even support that many OpenGL 2 features?

The extension mechanism provides all Ogl 2 features also for earlier versions. Ogl 2 only fixed several features as being mandatory. So yes, we have some features from 2.0 which were not part of 1.5. But the change from 1.5 to 2.0 was far less dramtaic than the major version change suggests.

OpenGL3 sounds good.

www.opengl.org announced on the 25th may that they will start to release Open GL 3.0 this year. There will be a lot support for brand new graphics cards. Sounds really good.

But as said earlier, all new features are already available through extensions. Just check the latest glext.h (I'll commit them to Irrlicht SVN soon, for now get them from opengl.org). So besides the architecture changes mentioned OpenGL 3 will simply include those extensions as mandatory elements of the API.

It also said that then OpenGL 3.0 will have an easier API

hybrid · Post by **hybrid** » Tue Jun 05, 2007 9:13 am

That depends on how used you are to the old one and how complex it is to change the underlying structures to fit the new API. Don't forget that by using Irrlicht you're not exposed to OpenGL anymore, so it wouldn't change anything for Irrlicht users. Only for those extending Irrlicht will have to mess with it.

any ideas if openGL will have an Object-Oriented Interface or still this C-Style one?
