Overview
vkDOOM3 adds a Vulkan renderer to the GPL DOOM 3 BFG Edition. It was written as an example of how to use Vulkan for writing something more sizable than simple recipes. It covers topics such as General Setup, Proper Memory & Resource Allocation, Synchronization, Pipelines, etc. Note this is an unofficial release.
NOTE: For those just wanting to dive straight into the Vulkan code you can find it here... neo/renderer/Vulkan. Also you can just search for ID_VULKAN.
TODO
As of initial release all maps load and are playable. However, the code base is not in complete parity with the OpenGL renderer. Here are some notes on what is still left to do or address.
- Anything using _accum is broken.
- Some SWF masks will render black in a few places.
- Render debug functionality is largely missing. Compare RenderDebug_GL to RenderDebug_VK.
- Screenshots aren't implemented atm.
- The window will resize and go from windowed <-> fullscreen properly. But not all swapchain invalidation cases are handled.
- Some cvars from pure BFG may not function as expected.
Building
Windows
Prerequisites:
- Git for Windows
- Vulkan SDK (several versions tested, but best to go with latest)
- A Vulkan-capable GPU with the appropriate drivers installed
- DirectX SDK June 2010
Start Git Bash and clone the vkDOOM3 repo:
git clone https://github.com/DustinHLand/vkDOOM3.git
Visual Studio
Install Visual Studio Community with Visual C++ component. (Make sure you also check MFC/ATL in individual components. Community doesn't enabled this by default, and you may have issues compiling.)
Open the Visual Studio solution, neo\doom3.sln, select the desired configuration and platform, then
build the solution. (GL=OpenGL, VK=Vulkan)
Note: I have been working with VS2015 and have not tried 2017 yet. Contributions welcome. :)
MinGW
Not currently supported.
Linux
Not currently supported.
