Vulkan Hardware Capability Viewer 2.01 released

 Posted on October 5, 2019  |  Sascha

Version 2.01 of the Vulkan Hardware Capability Viewer is now available for all platforms (Windows, Linux, Android). This version has been updated to Vulkan Headers 1.1.123, adding support for all new extensions introduced with this header: VK_KHR_shader_subgroup_extended_types The main reason for this update is another one though, as it also fixes a bug for extension properties with array values not being properly saved to json and thus not being stored in the database.

Vulkan Hardware Capability Viewer 2.00 released

 Posted on August 30, 2019  |  Sascha

Version 2.00 of the Vulkan Hardware Capability Viewer is now available for all platforms (Windows, Linux, Android). The major version bump is caused by a big change in how the code for reading device extension properties and features is generated. You can find a detailled rundown on how this works below. You can download the new version from vulkan.gpuinfo.org/download.php. Appimage for Linux Deploying Qt applications on Linux is not as easy as on Windows, esp. [Read More]

Vulkan examples for ray traced shadows and reflections using VK_NV_ray_tracing

 Posted on April 27, 2019  |  Sascha

After adding a basic Nvidia RTX ray tracing example last week, I spent some more time with Vulkan and the VK_NV_ray_tracing extension. The result are two new, more advanced examples that I just uploaded to my Vulkan C++ example repository. As with the basic example I tried to keep them as straight forward as possible with all the relevant code parts put into one source file, so that following and building upon is as easy as possible.

New Vulkan example on raytracing using VK_NV_ray_tracing

 Posted on April 21, 2019  |  Sascha

With all the new Turing extensions that NVIDIA has released alongside it’s new GPU architecture, I decided to replace my GTX 980 with a RTX 2060, mainly for the purpose of doing RTX ray-tracing related Vulkan stuff and also checking out things like mesh and task shaders. Getting my first RTX accelerated ray tracing example up and running was pretty easy, thanks to tutorials like the one from NVIDIA and iOrange. [Read More]

Turing shader extensions and Visual Studio 2019 support for SPIR-V Extension

 Posted on April 20, 2019  |  Sascha

I have released an updated version of the SPIR-V Extension to the Visual Studio Marketplate. If you already have this installed in Visual Studio, you can update it from the extension window. Version 0.6 adds support for Visual Studio 19 and nvidia’s new turing shader extension, allowing you to generate SPIR-V from the IDE for ray tracing (generation, hit, miss, etc.), mesh and task shaders. Supported shader extensions: .vert (Vertex shader) . [Read More]

Device based views for the Vulkan hardware database

 Posted on April 13, 2019  |  Sascha

I have just pushed the first big fundamental update to the Vulkan hardware database since it went live in february 2016. With more than 5,000 reports uploaded it already contains lots of valuable data, but I felt that the visualization was lacking. When creating the Vulkan hardware database, I took the same approach as with the OpenGL and OpenGL ES database, making the web front-end more or less as pretty view of the database setup. [Read More]

Flipping the Vulkan viewport

 Posted on March 29, 2019  |  Sascha

Introduction This short tutorial deals with Vulkan’s viewport setup, which differs from the one in OpenGL and other APIs. I’ll try to explain what it takes to get your (OpenGL) scene rendered properly, and how e.g. VK_KHR_MAINTENANCE1 can help you deal with differences across the APIs, something that’s esp. helpful if you try to add Vulkan as a backend to you renderer without wanting to alter your actual scene data.

Adding support for glTF meshes without indices

 Posted on March 23, 2019  |  Sascha

I have pushed an update to my Vulkan glTF PBR 2.0 application that adds support for rendering primitives without indices. Up until now, all primitives of a glTFs scene had to come with indices to be rendered by the application, which is usually the case for more complex scenes. After getting a request for this, and checking with the glTF 2.0 spec, primitives without indices are actually a valid glTF 2. [Read More]
