Implementation of Peter Shirley's Ray Tracing in One Weekend book in the Zig programming language.

Tested on Zig version 0.9.1.

Clone the repo and jump into it:

git clone [email protected]:jackdbd/path-tracer.git
cd path-tracer

In order to use this library and run the examples you will need zig version 0.9.1. You can get it using zigup:

zigup fetch 0.9.1
zigup 0.9.1

Build and run the executable in debug mode.

zig build run

Build the executable in release-fast mode, then run it.

zig build -Drelease-fast --verbose
# run it
./zig-out/bin/ray-tracing-in-one-weekend-zig

Run all tests:

zig build test

Otherwise, run all tests defined in a single file:

zig test src/material.zig
zig test src/utils.zig
zig test src/render_targets/ppm_image.zig --main-pkg-path ./src

Format all zig code

zig fmt src

• implement example with async and await
• implement more scenes
• improve documentation about Monte Carlo path tracing algorithm and global illumination model
• generate docs with zig test src/utils.zig -femit-docs=./docs or similar command
• fix issues with zig-clap
