This is the Root repository for my raytracing project. There are two ray tracers, a multithreaded cpu based raytracer and an in progress vulkan raytracer.
The cpu raytracer initially used Raytracing in a Weekend book series by Peter Shirley (https://raytracing.github.io/) as
a guide.
It has however expanded far past the material taught in the book.
Supported Features
- Gui Editor
- Multithreading
- Post Processing Pipeline
- Many Materials
see https://github.com/scifi6546/ray_tracing/tree/master/cpu_rt for more information.
The vulkan raytracer is still in progress however it supports runtime configurable render pipelines. It uses the vulkan raytracing extensions. It uses shaders writen in glsl and compiled to spir-v at build time.
A CPU raytracer based off of the Raytracing in a Weekend book series by Peter Shirley (https://raytracing.github.io/) and an in progress real time Vulkan rendering engine. It uses a bounding volume hierarchy inorder to accelerate ray tracing.
The cpu raytracer is based off of the Raytracing in a Weekend series by Peter Shirley. It features multiple materials, a GUI written with egui and support for loading arbitrary scenes. The supported materials are described below.
An in progress vulkan rendering engine is currently under construction. It is planned to use ray tracing. Currently it supports loading some of the scenes from the cpu Minya renderer.
A rendering of the cornell box is shown below.
