glfw VS Vulkan

And this is how https://github.com/go-gst/go-gst, https://github.com/go-gl/glfw, and even https://fyne.io/ are using system libraries to propose a lot of functionalities.

I'm looking for something that's relatively low-level (not a game engine) but preferably abstracts some of the boilerplate away and is cross-platform. Something like go-bgfx would have been perfect for me, but it has been long abandoned. The only real remaining option appears to be the glfw-bindings go-gl/glfw. Otherwise, I could make use of cgo to wrap some c/c++ code myself. I'm somewhat hesitant to go with glfw, because openGL isn't supported on all platforms (but realistically, I'm not going to publish anything that needs to go on mobile), and doesn't support raytracing, which I eventually want to mess around with too.

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.

This is the reference I used. https://github.com/SaschaWillems/Vulkan/blob/master/examples/hdr/hdr.cpp

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:

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.

P.S. do you know of Sascha Willems’ code? https://github.com/SaschaWillems/Vulkan

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)

Another way I saw some projects start was by using example base classes (either Sascha Willems' implementations or the framework used by Khronos Samples).

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.

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.
