FMI Raytracer

University project to make a GPU raytracer.

This is a work in progress. Currently it can only render a set of spheres hardcoded in the shader. In addition most of the parameters for Vulkan are hardcoded and picked just so that it runs on the hardware I am testing on.

How does it work

A compute shader is used to trace a ray for each pixel. The result is stored in an image, which is later copied to the framebuffer to be presented to the screen.

List of features:

• geometry: sphere
• geometry: triangle mesh
• material: opaque object
• material: transparent object
• light: point light
• light: rectangle light

Dependencies

• Vulkan and Vulkan.hpp - graphics and compute
• Glfw3 - window creation
• glsllangValidator - compiler from GLSL to SPIR-V

Building

This project comes with an adhoc make + cmake build script, which will only work with clang or g++ because of hardcoded compiler flags and will probably only work on Linux.

• install vulakn, glfw3 and glsllangValidator system-wide. Vulkan.hpp is automatically downloaded by the makefile.

• build with one of

  make build
  make build PROFILE=release

• or build and run with one of

  make run
  make run PROFILE=release

I may fix it someday if I find an adequate build system for C++.
