Vulkan Ray Tracing

Vulkan LogoThe Khronos® Group ratified and released the Vulkan® Ray Tracing provisional extensions, creating the industry’s first open, cross-vendor, cross-platform standard for ray tracing acceleration. Primarily focused on meeting desktop market demand for both real-time and offline rendering, the release of Vulkan Ray Tracing as provisional extensions enables the developer community to provide feedback before the specifications are finalized. Comments and feedback will be collected through the Vulkan GitHub Issues Tracker and Khronos Developer Slack. Developers are encouraged to share comments with their preferred hardware vendors. The specifications are available today on the Vulkan Registry.

The Khronos Vulkan Ray Tracing Task Sub Group (TSG) wrote a detailed blog to accommodate the release of the Ray Tracing provisional extensions. In the blog, the Vulkan Ray Tracing TSG gives an overview of each extension and provides links to more resources.

The Latest Vulkan Educational Resources

Vulkan LogoWe often hear that developers would like a single location to find all the available resources for learning Vulkan, so we created a list of the most up-to-date and valuable set of resources available. We've made good progress on new resources, releasing the Vulkan Code Samples, which we encourage developers of all skill levels to explore.

However, there is always more we can do to improve the state of available educational resources so expect more from us this year. In particular, with many events cancelled or delayed in 2020, we will be exploring ways to take that educational content online to make sure developers don't miss out on the valuable insight these event session's provide. We will continue to expand this list moving forward which you can find here

In addition to the educational resources, Vulkan has recently announced an update to the Vulkan Guide. The Vulkan Guide is designed to help developers get up and going with the world of Vulkan. It is aimed to be a light read that leads to many other useful links depending on what a developer is looking for, and now the guide has been updated to include 1.1 and 1.2 extensions. 

Learning from Home with 3D Content


Space ShuttleIn the last several weeks, learning has moved from the classroom into the home, as schools across the world have temporarily closed.

The old way of learning involved reading textbooks or consuming content delivered through paper handouts. Sometimes live specimens or scale models could be used to enliven lesson plans, but this delivery method involved complex preparations and procurement of live specimens, as well as other costly materials. Now with 3D models, things have changed.

Vulkan Mobile Best Practices - Management of Command Buffers and Multi-Threaded Recording

Arm LogoOne way to take advantage of all the CPU cores available to us is to implement multi-threaded recording of draw calls. In tile-based renderers (found in most mobile GPUs), the best approach to split the draw calls is to record them in secondary command buffers. This way they can all be submitted to the same render pass and take advantage of tile-local memory. Read more...
