Formerly known as Longs Peak, the OpenGL Architecture Review Board officially announced OpenGL 3 at SIGGRAPH yesterday during the OpenGL Birds of a Feather session! Sweet!
"The OpenGL ARB officially announced OpenGL 3 on August 8th 2007 at the Siggraph Birds of a Feather (BOF) in San Diego, CA. OpenGL 3 is the official name for what has previously been called OpenGL Longs Peak. OpenGL 3 is a great increase in efficiency in an already excellent API. It provides a solid, consistent and well thought out basis for the future. OpenGL 3 is a true industry effort with broad support from all vendors in the ARB. The OpenGL 3 specification is on track to be finalized at the next face-to-face meeting of the OpenGL ARB, at the end of August. This means the specification can be publicly available as soon as the end of September, after the mandatory 30 day Khronos approval period has passed. Also presented today were the changes to the OpenGL Shading Language that will accompany OpenGL 3."
I might get shot by the OpenGL purists for saying this, but the Mount Evans refresh of OpenGL 3 has some obvious similarities to D3D10, with the introduction of geometry shading, an integer instruction set, uniform buffers, native support for nonlinear colour spaces and more. The update is expected in about 3-5 months time.
As far as the new effects framework goes, glFX will primarily support OpenGL 2.1, 3.0 and ES 2.0 targets, all via tight integration with COLLADA FX, with the Khronos Group (and particularly NVIDIA it seems) leading the glFX effort.
Mount Evans will require DirectX 10 supporting hardware, with Longs Peak targeting the SM3.0-supporting class of DX9 parts out there. There's a utility library to come that's a bit like GLU, and the entire OpenGL 3 process should calm down very soon so the ARB can finalise everything and look to shipping Mount Evans.
You can grab the presentations from yesterday at the Khronos Group website and we congratulate the ARB for finalising 3!
