# vulkan-ray-tracing

A few updates:

- Fixed skybox texture using the swapchain format instead of RGBA.

- Added cmake file to build the project

The ray tracing code is based on this [blogpost](http://blog.three-eyed-games.com/2018/05/03/gpu-ray-tracing-in-unity-part-1/).

My first attempt at using Vulkan, the ray tracing algorithm is still very basic.

 - The ray tracing algorithm is executed for each pixel in a compute shader

 - The compute shader writes the color result in a texture

 - The graphics pipeline merely renders the texture on the screen

## How to build

To compile this project, you will need the following libraries

 - Vulkan

 - GLFW

 - [stb (for image loading)](https://github.com/nothings/stb)

Run the following command to build the project

```

mkdir -p build

cd build

cmake ..

make

./vulkan_ray_tracer

```
