Vulkan Raytracing Project

A real-time raytracing program in Vulkan. This program uses compute shaders to compute the raytraced pixels and optionally uses Intel's Open Image Denoiser to denoise the raytraced image.

Build

Windows Build

Prerequisites:

• CMake <=3.10
• LunarG Vulkan SDK
• Visual Studio

Build Instructions

Note: you can do step 2 to 7 on the command line if cmake is added to the PATH environment variable. Just run cmake -G <Visual Studio Generator> -DPLATFORM="Windows" ../ inside the build folder.

1. Create a build folder inside the project root directory
2. Open the CMake GUI
3. Clear the CMake cache (File -> Delete Cache)
4. Specify the source directory to be the project root directory
5. Specify the build directory to be the build folder inside the project root directory
6. Add an entry of type STRING with PLATFORM as the name and Windows as the value
7. Click on Configure then Generate. It should generate VulkanRaytracing.sln inside the build folder.
8. Close CMake and open VulkanRaytracing.sln with Visual Studio.
9. Click on the VulkanRaytracing solution in Solution Explorer
10. Select the build (e.g. Debug x64 or Release x64)
11. Click on Build -> Build VulkanRaytracing
12. Copy the executable from the output folder to the project root directory
13. Copy all the DLLs from lib/windows/DLLs/ to the project root directory
14. Run the executable in the project root directory
