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
go-simple-ray uses JSON to describe scenes. Scenes are composed of the following:
eye- the cameras positionobjects- a list of objects (spheres)lights- a list of lightsambientLight- 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.
