Conformance Tests created to accompany API specification and reference documentation available now; Full backwards compatibility maintained
July 22nd 2013 – SIGGRAPH - Anaheim, CA – The Khronos™ Group today announced the immediate release of the OpenGL® 4.4 specification, bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface). OpenGL 4.4 unlocks capabilities of today’s leading-edge graphics hardware while maintaining full backwards compatibility, enabling applications to incrementally use new features while portably accessing state-of-the-art graphics processing units (GPUs) across diverse operating systems and platforms. Also, OpenGL 4.4 defines new functionality to streamline the porting of applications and titles from other platforms and APIs. The full specification and reference materials are available for immediate download at http://www.opengl.org/registry.
In addition to the OpenGL 4.4 specification, the OpenGL ARB (Architecture Review Board) Working Group at Khronos has created the first set of formal OpenGL conformance tests since OpenGL 2.0. Khronos will offer certification of drivers from version 3.3, and full certification is mandatory for OpenGL 4.4 and onwards. This will help reduce differences between multiple vendors’ OpenGL drivers, resulting in enhanced portability for developers.
“The delivery of conformance tests for OpenGL 4.4 is a significant milestone – as it is vital for developers to be able to rely on the API they are trusting to accelerate their content across multiple platforms,” said Barthold Lichtenbelt, OpenGL ARB working group chair. “The OpenGL ARB is committed to continue to deepen communications with the developer community so we can continue to build OpenGL functionality that creates real-world business opportunities for the 3D industry.”
New functionality in the OpenGL 4.4 specification includes:
Extensions released alongside the OpenGL 4.4 specification include:
“AMD has a long tradition of supporting open industry standards, and congratulates the Khronos Group on the announcement of the OpenGL 4.4 specification for state-of-the-art graphics processing,” said Matt Skynner, corporate vice president and general manager, Graphics Business Unit, AMD. “Maintaining and enhancing OpenGL as a strong and viable graphics API is very important to AMD in support of our APUs and GPUs. We’re proud to continue support for the OpenGL development community.”
“We worked closely with Khronos on OpenGL 4.4, so we wanted to make sure the day it was announced we had compliant drivers for our Fermi and Kepler GPUs,” said Tony Tamasi, senior vice president, Content and Technology at NVIDIA. “We’re also working to bring support to Tegra, so developers can create amazing content that scales from high-end PCs down to mobile devices.” (These products are based on the published OpenGL 4.4 Specification, and are submitted to, and are expected to pass, the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.)
There is an OpenGL BOF “Birds of a Feather” Meeting on Wednesday July 24th at 7-8PM at the Hilton Anaheim, California Ballroom A & B, where attendees are invited to meet OpenGL implementers and developers and learn more about the new OpenGL 4.4 specification.
The Khronos Group is an industry consortium creating open standards to enable the authoring and acceleration of parallel computing, graphics, vision, sensor processing and dynamic media on a wide variety of platforms and devices. Khronos standards include OpenGL®, OpenGL® ES, WebGL™, OpenCL™, WebCL™, OpenVX™, OpenMAX™, OpenVG™, OpenSL ES™, StreamInput™ and COLLADA™. All Khronos members are able to contribute to the development of Khronos specifications, are empowered to vote at various stages before public deployment, and are able to accelerate the delivery of their cutting-edge media platforms and applications through early access to specification drafts and conformance tests.
