#Lisp tracer

A ray tracer made in Common Lisp following The Ray Tracer Challenge by Jamis Buck

#Example

#How to run

You need to enable double floats. We need the higher precision to avoid acne.

(setf *read-default-float-format* 'double-float)

Then evaluate lisp-tracer.asd and go to the corresponding lisp-tracer package in the REPL. The renders can be found in src/renders, and will create a picture.ppm in root.

#Tests

You can run tests by evaluating lisp-tracer-tests.asd, then running

(run :lisp-tracer-tests :style :spec)

from lisp-tracer-tests package.
