Build your own 3D renderer - Java

This repository contains an implementation of the projects outlined in the Build your own 3D renderer workshop. The implementation is in Java, outputting to a .png file.

Quick Start

git clone https://github.com/avik-das/build-your-own-raytracer-java.git
cd build-your-own-raytracer-java

# Build the raytracer
gradle build

# Run it, outputting to a file called "test.png" in the current directory
java -jar build/libs/build-your-own-raytracer-java-1.0-SNAPSHOT.jar test.png

Scene Definition

While each project typically asks the reader to add new data to the scene definition, the number of classes to add in Java would drown out the main changes needed to implement a particular project. For that reason, all the data model classes and the scene definition have been set up in a single commit at the beginning of the repository history.

Tagged milestones

Each commit of the project implements one of the projects in the workshop. If you wish to implement one of the projects yourself, you can check out the before-project-N tag, where N is the project number. This will put you in a state just prior to the implementation of that project, with all previous projects implemented:

# Prepare to implement Project 4
git checkout before-project-4
