Vulkan working group has released a major Vulkan 1.0 specification update

The Vulkan working group has released a major Vulkan 1.0 specification update that adds eighteen new KHR extensions. They include KHR replacements for the experimental KHX_external_memory_* and KHX_external_semaphore_* extensions released earlier this year, incorporating changes based on developer and implementer feedback. The release also adds a set of KHR_external_fence_* extensions. Together, these extensions allow applications to share memory and synchronization primitives across process and API boundaries. Two new extensions, KHR_dedicated_allocation and KHR_get_memory_requirements2, provide more expressive and extensible ways for applications to optimize their GPU memory allocation policies. KHR_16bit_storage, KHR_storage_buffer_storage_class, and KHR_variable_pointer allow Vulkan implementations to accept shader programs containing new programming constructs recently added to the SPIR-V intermediate shading language.

The new extensions are accompanied by a new release of the Vulkan 1.0 conformance test that checks that the new extensions are implemented correctly, and a new Vulkan SDK that provides loader and validation support and a snapshot of a compatible release of the GLSLang shader compiler. All of the new extensions are supported in the latest NVIDIA drivers, and support from other GPU vendors is in progress.

Microsoft announced updates to Paint 3D: Magic select enhancements & drawing tools. Paint 3D also now supports a new industry-wide open standard for 3D file sharing called GLB, a part of gLTF (GL Transmission Format). This allows for faster and more efficient transfer of 3D assets by outputting only one container for all assets, minimizing the file size and the ability to use the files across other programs as a universal format. glTF (GL Transmission Format) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. The glTF specification is managed by the Khronos Group.

A reality check for virtual headsets

• Tags:

Games developers know how to engage players and keep them interested, and how to tell stories in a non-linear fashion. And they have for years created content in three dimensions, a basic requirement for VR. Indeed, virtual reality is integrating games and the broader technology industry as never before. “It’s like two continents that were apart, and continental drift is bringing them together,” says Neil Trevett of the Khronos Group, a non-profit industry group.
