Open Source Vulkan Renderer for Doom 3 BFG Edition is now available


Recommended Posts

Dustin Land of id Software has been working on the "vkNeo" project in his spare/personal time as a Vulkan renderer for Doom 3 BFG / idTech4, which was open-sourced a few years back. This is along the same lines as the vkQuake open-source port of the original Quake to running on Vulkan.

How much code did it take to write for a Vulkan renderer for Doom 3? The commit diff adding the Vulkan code comes in at 602,265 lines, including blank/comment lines and that also includes some shaders/SPIR-V and plenty of header files.

 

The Doom 3 Vulkan code was open-sourced over night via vkDOOM3 on GitHub for those interested. Land commented, " 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."

This is going to be interesting.
