What's your opinion on using a library like bgfx instead of a custom GLFW + GLM + GLAD approach? With the upcoming release of Vulkan, should i wait for it and use it, or work on top of an abstraction like bgfx? It has it's own shading language.

The shading language of bgfx can be, fairly trivially, replaced with whatever you want. bgfx is fairly easy to get up and going, and Branimir has been working pretty heavily on the DX12 stuff, so that's available (although the performance wasn't up there with DX11 yet, the last time I tried it, but he's actively working on that).

I'm a big fan of bgfx. It certainly takes a little getting used to but once you get your bearings things start moving along very quickly. Branimir is a smart fellow and extremely active on the project. He's quick to reply to email and github issues. Would definitely recommend.

When Vulkan comes out, I assume that if bgfx development is still active, then a vulkan back-end will be created underneath the bgfx abstraction, so you'll get that for free (or you can help work on the vulkan back-end yourself, toosmile.png
 
Unless you want to create a GPU abstraction for the sake of it, then use a library like bgfx (or a full engine). Writing a game on top of a low-level API like D3D/GL/Vulkan is a terrible idea, and creating a well-designed abstraction-layer on top of D3D/GL/Vulkan is a big project in itself.
 
I haven't used bgfx but I've had a quick peek at it's code. The abstraction seems very good, but some of the internal code is terrible sad.png That just means it's got a lot of room for improvement and optimization though laugh.png

      Hey, I was wondering if on mobile development (Android mainly but iOS as well if you know of it), if there is a GPUView equivalent for whole system debugging so we can figure out if the CPU/GPU are being pipelined efficiently, if there are bubbles, etc. Also slightly tangent question, but do mobile GPU's have a DMA engine exposed as a dedicated Transfer Queue for Vulkan?

      I am working on a project which needs to share render targets between Vulkan and DirectX12. I have enabled the external memory extension and now allocate the memory for the render targets by adding the VkExportMemoryInfoKHR to the pNext chain of VkMemoryAllocateInfo. Similarly I have added the VkExternalMemoryImageCreateInfo to the pNext chain of VkImageCreateInfo.
      After calling the get win32 handle function, I get some handle pointer which is not null (I assume it is valid).
      VkExternalMemoryImageCreateInfoKHR externalImageInfo = {}; if (gExternalMemoryExtensionKHR) { externalImageInfo.sType = VK_STRUCTURE_TYPE_EXTERNAL_MEMORY_IMAGE_CREATE_INFO_KHR; externalImageInfo.pNext = NULL; externalImageInfo.handleTypes = VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KH imageCreateInfo.pNext = &externalImageInfo; } vkCreateImage(...); VkExportMemoryAllocateInfoKHR exportInfo = { VK_STRUCTURE_TYPE_EXPORT_MEMORY_ALLOCATE_INFO_KHR }; exportInfo.handleTypes = VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_FD_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_KMT_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT_KHR | VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KHR; memoryAllocateInfo.pNext = &exportInfo; vkAllocateMemory(...); VkMemoryGetWin32HandleInfoKHR info = { VK_STRUCTURE_TYPE_MEMORY_GET_WIN32_HANDLE_INFO_KHR, NULL }; info.memory = pTexture->GetMemory(); info.handleType = VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KHR; VkResult res = vkGetMemoryWin32HandleKHR(vulkanDevice, &info, &pTexture->pSharedHandle); ASSERT(VK_SUCCESS == res); Now when I try to call OpenSharedHandle from a D3D12 device, it crashes inside nvwgf2umx.dll with the integer division by zero error.
      I am now lost and have no idea what the other handle types do.
      For example: How do we get the D3D12 resource from the VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR handle?
      I also found some documentation on this link but it doesn't help much.
      https://javadoc.lwjgl.org/org/lwjgl/vulkan/NVExternalMemoryWin32.html
      This is all assuming the extension works as expected since it has made it to the KHR

      I am trying to get vulkan on android working and have run into a big issue. I don't see any validation layers available. I have tried linking their libraries into mine but still no layers. I have tried compiling it into a library of my own but the headers for it are all over the place. Unfortunately , google's examples and tutorials are out of date and don't work for me. Any idea what I have to do to get those layers to work?

      It seems like nobody really knows what is the correct behavior after window minimizes in Vulkan.
      I have looked at most of the examples (Sascha Willems, GPUOpen,...) and all of them crash after the window minimize event with the error VK_ERROR_OUT_OF_DATE either with an assertion during acquire image or after calling present. This is because we have to recreate the swap chain.
      I tried this but then Vulkan expects you to provide a swap chain with extents { 0, 0, 0, 0 }, but now if you try to set the viewport or create new image views with extents { 0, 0, 0, 0 }, Vulkan expects you to provide non-zero values. So now I am confused.
      Should we just do nothing after a window minimize event? No rendering, update, ...?

      Hi all,
      First time poster here, although I've been reading posts here for quite a while. This place has been invaluable for learning graphics programming -- thanks for a great resource!
      Right now, I'm working on a graphics abstraction layer for .NET which supports D3D11, Vulkan, and OpenGL at the moment. I have implemented most of my planned features already, and things are working well. Some remaining features that I am planning are Compute Shaders, and some flavor of read-write shader resources. At the moment, my shaders can just get simple read-only access to a uniform (or constant) buffer, a texture, or a sampler. Unfortunately, I'm having a tough time grasping the distinctions between all of the different kinds of read-write resources that are available. In D3D alone, there seem to be 5 or 6 different kinds of resources with similar but different characteristics. On top of that, I get the impression that some of them are more or less "obsoleted" by the newer kinds, and don't have much of a place in modern code. There seem to be a few pivots:
      The data source/destination (buffer or texture) Read-write or read-only Structured or unstructured (?) Ordered vs unordered (?) These are just my observations based on a lot of MSDN and OpenGL doc reading. For my library, I'm not interested in exposing every possibility to the user -- just trying to find a good "middle-ground" that can be represented cleanly across API's which is good enough for common scenarios.
      Can anyone give a sort of "overview" of the different options, and perhaps compare/contrast the concepts between Direct3D, OpenGL, and Vulkan? I'd also be very interested in hearing how other folks have abstracted these concepts in their libraries.
