Sphere-ray intersection
Just returning point along ray
Hey, crappily tracing a scene
screen -> view
A repl show! function
Actually projecting rays through screen
Reading stuff out of a file
Whoops, not returning t0 every dang time
Pointing the ray in the right direction
Pretty unsuccessfully trying to parallelize things
show-file! function
Very hardcoded reflection
Evaling in the right namespace
Slightly more good parallelization
Passing in the recursion depth
Got rid of the aspect ratio
Shape protocol
Planes!
