go-simple-ray

go-simple-ray is a very basic raytracer used as a learning exercise. It's limitations:

• No proper lighting.
• Minimal reflection and refraction implemented.
• Only objects to be handled are spheres since the maths for sphere -> ray intersection is very simple

Scenes:

go-simple-ray uses JSON to describe scenes. Scenes are composed of the following:

• eye - the cameras position
• objects - a list of objects (spheres)
• lights - a list of lights
• ambientLight - the global illumination (a light)

Spheres contain:

• a position (x, y, z), a radius (r), a color (r, g, b) and a diffuse component (a, b, c)

Lights contain:

• A light contains a position (x, y, z) and a color (r, g, b)

This is a VERY basic raytracer, but i think it's quite clean, and could be used by someone to learn.
