Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Usages for vkCreateHeadlessSurfaceEXT
Samples in https://github.com/SaschaWillems/Vulkan have shown how to use vkCreateHeadlessSurfaceEXT. But these headless samples crash at acquireNextImage from the swapchain. Now I guess the problem lies in the vulkan-wsi-layer.

Question about descriptor buffers.
Hi, I'm messing with descriptor buffers but I've came across certain issues I can't seem to solve. I'm using this tutorial as reference. I've tried UBOs and SSBOs, it works perfectly and there is no need to change the buffers offsets when recording a command buffer because I can access them by index like this:

Need help learning descriptor sets
Hi I am trying to learn Vulkan for an upcoming project and I have so far found everything to be straight forward if very verbose. I have now come to descriptor sets, layout bindings and the so forth and it's got more confusing than I can work out. I have been following this github repo for a headless compute example and it works fine as it is. But when I tried to add an additional storage buffer to the test shader than it comes with I am unable to copy the data over instead just getting a whole collection of 0's.

Vulkan ray tracer with fog and stuff
P.S. do you know of Sascha Willems’ code? https://github.com/SaschaWillems/Vulkan

Proper way to access a read-only texture that has no sampler from an hlsl compute shader?
BTW, this problem can be reproduced as described below: - clone https://github.com/SaschaWillems/Vulkan.git - build the project and run it with arguments : -v - s hlsl to enable the validation layer and to use hlsl code - run ComputeShader project. The following validation error "Type mismatch on descriptor slot ..." will be shown in the console. - to fix it, as suggested above, you can replace the 3rd line of emboss.comp, sharpen.comp, and edgedetect.comp from: Texture2D inputImage : register(t0); //Creates validation errors to RWTexture2D inputImage : register(u0); //no validation errors (you'll then need to recompile the shaders to spv with a proper hlsl compiler such as Microsoft dxc)

Recommendations on how to start a small Vulkan project
Another way I saw some projects start was by using example base classes (either Sascha Willems' implementations or the framework used by Khronos Samples).

I've been working on a real-time ray tracing renderer
It's not a tutorial but I'd recommend Sascha Willems examples. A good next step could be adding models and shadows (see https://github.com/SaschaWillems/Vulkan/tree/master/examples/raytracingshadows). It's a single file but you can easily understand what each function does.

Add a second texture to Sascha Willems glftLoading app
Exactly as u/aerorang said. I recommend comparing your linked example with Sascha's gtTF Scene rendering example where he adds a normal map along with the base albedo texture. He also marked important parts of the code with the POI keyword, so you can search for them in the code.

Question About queueIndex parameter of vkGetDeviceQueue function
I've been reading the Vulkan Tutorial, and I was looking at https://github.com/Overv/VulkanTutorial/blob/main/code/31_compute_shader.cpp

vulkan-tutorial.com seems to be down
Yeah it seems to be down. Meanwhile you can follow the PDF/EBOOK available on their github

VkWaitForFences blocking forever
In the original Vulkan tutorial code (based on 15_hello_triangle.cpp) the main loop of acquiring the image, executing the command buffer and presenting it is based on inflight frames. Nothing special.

Understanding queuing multiple frames at a time
This is a tricky subject; it seems like even Vulkan-Tutorial.com gets it wrong. Here's an issue I submitted to them: https://github.com/Overv/VulkanTutorial/issues/226
