Ray tracing sample using Vulkan API

This project provides ray tracing applications sample

Build

Build as you would any other CMake-based project. For example on Linux:

cd vk_graphics_rt
mkdir build
cd build
cmake ..
make -j8

On Windows you can directly open CMakeLists.txt as a project in recent versions of Visual Studio. Mingw-w64 building is also supported.

Executable will be built in bin subdirectory - vk_graphics_rt/bin/renderer

Run

• Execute "./raytracing" from the "bin" directory
• Select rendering mode via '1' (rasterization),'2' (raytracing) buttons.
• If you don't have support for hardware ray tracing, set "ENABLE_HARDWARE_RT = false" in simple_renderer.h
• If you are going to work with this sample via kernel_slicer, edit appropriate paths in 'run_slicer.sh' file or use VS Code config for this sample from kernel_slicer repo.

Dependencies

Vulkan

SDK can be downloaded from https://vulkan.lunarg.com/

GLFW

https://www.glfw.org/

Linux - you can install it as a package on most systems, for example:

sudo apt-get install libglfw3-dev

Windows - you don't need to do anything, binaries and headers are included in this repo (see external/glfw directory).

Additional dependencies

Can be installed by running provided clone_dependencies.bat script. So, if you clone this repo into vk_graphics_rt directory:

cd vk_graphics_basic
clone_dependencies.bat

Or you can get them manually:

volk:

cd vk_graphics_rt/external
git clone --depth 1 https://github.com/zeux/volk.git

imgui:

cd vk_graphics_rt/external
git clone --depth 1 https://github.com/ocornut/imgui.git

vkutils:

cd vk_graphics_rt/external
git clone --depth 1 https://github.com/msu-graphics-group/vk-utils.git vkutils

Single header libraries

This project also uses LiteMath and stb_image which are included in this repo.
