pytracer

Ray tracing in Python. My implementation of The Ray Tracer Challenge by Jamis Buck.

Examples

Examples assume iTerm with imgcat installed.

If imagecat is not installed, pipe output to a .ppm file instead of into imgcat, and open with macos Preview, or another program that supports PPM files (try IrfanView).

Before running examples, be sure to install the project:

$ poetry install

Render a scene from a YAML file

pytracer examples/scene_reflection.yaml --width 1600 --height 800 |imgcat

Transparency

pytracer examples/transparency.yaml --width 1000 --height 500 | imgcat

World and Camera

$ poetry run python examples/world_and_camera.py | imgcat

Creating a PPM image from a pytracer Canvas

$ poetry run python examples/canvas_to_ppm.py | imgcat
