Ray-Tracing-Renderer

This is a tiny renderer based on three famous books. We use .ppm, a pixel map format to generate images.

Ray Tracing in One Weekend

Basic classes:

1. vec3: a simple way to express colors, locations and directions
2. ray: shooting from one point to another
3. camera: a positionable camera, allowing one to change its focus
4. hitable: an object that can be hit by a ray and returns hit infomation
   • hitable_list: store various hitables
   • sphere: a sphere hitable object
5. material: descibes how light reflects, scatters and refracts
   • lambertian: light reflects in all directions
   • metal: light obeys standard reflection
   • dielectric: light is allowed to refract

Features:

1. support calculating the process when light hits a hitbale object
2. antialising: by rasing sample rate ro denoise
3. support three ways to deal with light by changing the material of a hitable
4. defoucus blur: by changing the depth of field
