An implementation of a ray tracer based on the "The Ray Tracer Challenge" book in Python.
source venv/bin/activatepip install -r requirements.txt
python -m rayz
behave
Note: If you need print output while these are running, the behave.ini is configured to allow it, but you will also need to run with the --no-color option.
Note: Even easier than the above is the add a couple of lines to all output, then behave will get rid of them and you can see the output and the color.

The canvas is a grid of pixels. The grid is defined by the number of rows and columns. The rows are the Y axis and the columns are the X axis. The origin is the bottom left corner of the grid. The X axis increases to the right and the Y axis increases up.

Projectile hit the ground after 16 ticks.
A projectile is shot and the position is reported until it hits the ground. The path of the projectile is plotted on a canvas.
Run example:
python -m rayz && cp projectile.ppm /mnt/c/Users/craig
