A Golang implementation of ray tracing rendering engine

# compile render
go build render.go

# run with a scene file and designate the output image path
# render [-p[=nThread]] <path to csv file> <output path>
render -p test/sceneSimple.csv outSimple.png

All three datasets are in ./test/ folder, corresponding results are in the same folder.

You may modify the code in function RandomScene in ./render/scene.go to generate randomly placed sphere with varying materials.
