OpenGL Headline News
NVIDIA has just published the OpenGL extensions that expose the Pascal GPU architecture’s new hardware features. The extensions are available on GTX 1070 and GTX 1080 GPUs starting with the 367.XX drivers: Single Pass Stereo: GL_NV_stereo_view_rendering; Lens Matched Shading: GL_NV_clip_space_w_scaling; Improved Conservative Rasterization: GL_NV_conservative_raster_pre_snap_triangles; Double Precision Atomic Operations: GL_NV_shader_atomic_float64. Read an overview over these extensions, which complements the programming guide and sample code available in the NVIDIA VRWorks 2.0 SDK.
The Khronos Group announces the immediate availability of the OpenGL SC 2.0 specification for bringing programmable graphics to systems that require system safety certification. The OpenGL SC 2.0 API specification has been developed by the Khronos Safety Critical working group to address the unique and stringent requirements of high reliability display system markets, including FAA DO-178C and EASA ED-12C Level A for avionics, and ISO 26262 safety standards for automotive. Building on the large number of worldwide customer deployments and successful avionics certifications using OpenGL SC 1.0, OpenGL SC 2.0 enables high reliability system manufacturers to take advantage of modern graphics programmable shader engines while still achieving the highest levels of safety certification. The Official OpenGL SC 2.0 feedback forum is online.
GL_ARB_tessellation_shader support for Ivy Bridge and Haswell is now complete. This latest Intel OpenGL 4.0 work will be found in the next Mesa release due out around March.
AMD has announce it will start rolling out in January an open source set of tools called GPUOpen. The “All Open” stack will contain open source modules for two parallel stacks, each containing modules for OpenGL graphics, motion video codecs, and OpenCL GPU computation. The “Professional/Gamer” stack will include the open source motion-video module and a closed source OpenGL module. Its final OpenCL module will support both OpenCL and Vulkan. Linux will gain access to a full open source, high-performance driver stack, with the only constraint being that developers must use Vulkan instead of the older OpenGL.
The latest driver update covers GeForce 8 and 9 video cards allowing them to continue using hardware with modern OSes. From the changelog ““Fixed a bug that could cause texture corruption in some OpenGL applications when video memory is exhausted by a combination of simultaneously running graphical and compute workloads.”
