May the Source Be with You: NVIDIA Open Sources Material Definition Language SDK
Security, customizability, flexibility and cost are a few of the benefits of open-source software for developers.
They’ll get all these and more from NVIDIA’s Material Definition Language software development kit, which is available starting today as open source.
MDL software — a set of tools that integrate the precise look and feel of real-world materials into rendering applications — has long been supported by developers. It gives end-users the freedom to share physically based materials and lights between supporting applications.
For example, an MDL material — such as a specific piece of carpeting, upholstery or clothing — created in Allegorithmic Substance Designer can be saved to a library and then used in any other supporting application, like Adobe Dimension CC.

NVIDIA Announces Open-Source MDL SDK
In addition to announcing the Turing-based Quadro RTX GPUs with GDDR6 memory, NVIDIA used SIGGRAPH 2018 to announce their open-sourcing of the MDL SDK.
The MDL SDK is the Material Definition Language and is a programming language for defining physically-based materials for rendering, The MDL code can then be converted into GLSL, NVIDIA PTX, x86 instructions, or LLVM IR for making these assets more portable.

Mesa 18.1.6 Released With Build System Updates, Various OpenGL/Vulkan Driver Fixes
Mesa 18.1.6 is now available as the latest point release for Mesa 18.1 as the Q2'2018 release of this collection of open-source graphics drivers/infrastructure.
Mesa 18.1.6 just ships with over three dozen fixes compared to v18.1.5 from a few weeks back. The Mesa 18.1.6 release includes various Gallium3D fixes, different Autotools/Meson build system updates, corrections to MSAA corruption with AMD Vega, a DRIRC option to allow Metro Redux to work properly (again), support for using INTEL_DEBUG for setting Intel shader disk cache flags, and various other random fixes throughout.

Vulkan 1.1.83 Released With Minor Documentation Updates For SIGGRAPH
The Khronos Group has released Vulkan 1.1.83 as a routine maintenance update to the Vulkan 1.1 graphics/compute API to coincide with the start of ACM SIGGRAPH 2018 in Vancouver.
Vulkan 1.1.83 doesn't introduce any new extensions but just corrects a variety of documentation issues. It does prepare for some new extensions though as some extra bits are now reserved for pending vendor extensions. These reserved bits appear to be for some NVIDIA extension work.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
