vulkan-examples

I have added another example to my open source C++ Vulkan examples. The new one is about indirect drawing (including multi draw if supported). Contrary to their non-direct counterparts, the indirect drawing commands in Vulkan take their draw calls from a buffer that is ideally stored in device local memory. So instead of running single draw commands that get their index base, index count and instancing numbers passed by the host upon getting called, the indirect commands are backed by a buffer that stores an arbitrary number of draw commands.

Based on the recently updated deferred shading example, I have added a new example to my open source C++ Vulkan samples. This example adds dynamic shadows from multiple light sources, showcasing a few technologies that can be used to make rendering of multiple shadows more efficient. To achieve this, the example uses a layered depth attachment with one layer per light source that is sampled in the final scene composition. Traditionally one would do multiple passes to render the depth maps for the scene’s light source, and to avoid this the example also uses shader instancing by doing multiple invocations in the geometry shader.

Over the past few weeks and months I’ve been constantly working on my Vulkan examples, enhancing existing demos, adding new ones, fixing bugs reported and merging pull requests (thx to anyone that has contributed!). I even found some time to work on a Vulkn deferred shading playground using Crytek’s famous Sponza model. You can find the repository for it here. This Sunday I decided to visually upgrade the deferred shading example included in my samples repository. [Read More]

I’ve been speaking about my Vulkan launch day contributions and my experiences moving from OpenGL to Vulkan at the Khronos Munich Chapter Grand Opening last friday at the AMD offices. This was a great event, and finally getting to know some of the people in real was an awesome personal experience. So at this point I’d like to thank all the people that helped make this event happen and all these that attended, had a real blast talking and discussing about Vulkan! [Read More]

The last few weeks since the Vulkan launch (one month ago) have been pretty busy. I’ve been adding new examples to to my github repository (almost at 30), fixed some bugs (thanks to everyone that has contributed!) and finally added Android support to all examples (removing the few separate Vulkan Android samples). I also provide pre-built binaries for Windows, Linux and Android (only ARM right now) if you just want to try out the examples at vulkan. [Read More]
