Simple ray tracer written in Go.
go get github.com/Erdk/gort
cd $GOPATH/src/github.com/Erdk/gort
dep ensure
go build .
./gort -h
Gort started as my "pet project" I'm working on in my spare time, and I belive it'll stay this way for now, so please don't expect regular updates ;) The idea came to my mind after seeing Peter Shirley's books on Amazon about ray-tracing: "Ray Tracing in One Weekend", "Ray Tracing: The Next Week" and "Ray Tracing: The Rest of Your Life". I thought that this would be a good way to improve my programming skills and learn more about Golang ecosystem and best practises. Soo.. here we are :) As for books I highly recommend them, they're well written and quite easy to understand.
-w <width>
Width of generated image, by default 640.
-h <height>
Height of generated image, by default 480.
-s <samples-per-pixel>
Number of rays per pixel, by default 400.
-t <threads>
Number of parallel rendering jobs, by default 1. Set 0 for auto (max CPU threads).
-o <output-file>
Filename (without extension) of png with output, by default "output".
-i <input-file>
Filename of input file, if this flag is used then scene won't be randomly generated. By default empty.
-j <save-scene>
Save genereated scene before render to <output>.json, by default false.
-prof <profile>
Generate profiling profile to use with 'go tool pprof'. By default none (no profiling). Available profiles:

If present it'll show progress (in %).
-cu AxB
Compute unit, number of patch to compute at once by goroutine, by default 16x16.
