RayTracer

RayTracer, this project is about me (@CloudCodingSpace), creating a real-time raytracer pretty much from scratch with very less number of dependencies. The prefferred language of choice is indeed C++. And the graphics API is OpenGL.

Build

First you need to clone this repository using this command on your terminal or powershell :-

git clone --recursive https://github.com/CloudCodingSpace/RayTracer

Then simply run these commands on your terminal :-

mkdir bin
cd bin  
cmake ..  
cmake --build . --parallel

When you are finally done with building the project, then find your executable and run it. When you run the executable, then it will open a window and render the scene in real-time.

Dependencies

This project uses a couple of dependencies. Namely :-

• GLM
• TinyOBJLoader
• ImGUI
• GLFW
• GLAD

Features

• Can render a hdri panorama/equirectangular image as a skybox
• Can select the hdri panorama/equirectangular image during runtime
• Can save the scene as an png image, found at output/img.png that is present in the same folder as the RayTracer executable.
• Can render multiple spheres
• Can add spheres during runtime
• Can change the sphere properties during runtime through ImGui
• Can do some reflection and the number of bounces per ray can be controlled through the ImGui Settings panel
• The ImGui window can be dragged out of the parent window by the ImGui viewports feature
