A raytracer implemented in Clojure based on The Ray Tracer Challenge. Companion of disposedtrolley/raytracer.

• JDK 11, i.e. brew install openjdk@11
• Clojure CLI tools

The tick namespace provides two run functions to showcase the current state of the raytracer.

• run simulates a projectile moving through an environment after it's fired. The various positions of the projectile result in an arc.
  • clj -X raytracer.examples.tick/run
  • clj -X raytracer.examples.tick/run :velocity-multiplier 4
• run-with-canvas performs the same simulation as run, but will plot the positions of the projectile on a canvas which is then saved as a PPM file. The canvas is fixed-size so the velocity cannot be adjusted via a multiplier.
  • clj -X raytracer.examples.tick/run-with-canvas :outfile '"/full/path/to/outfile"'
