Implement a raytracer and simulate real-life light interactions with objects (like shadows/reflections) while experimenting with rendering objects made up of different materials (like dielectrics or specular).

In this project we:

• Render a couple of objects in flat color.
• Simulate specular/shiny surfaces with Blinn-Phong shading.
• Render shadows.
• Simulate reflective and dielectric materials using Schlick’s approximation to Fresnel’s reflection.
• Simulate the attenuation of light while passing through dielectrics with Beer's law.

1. Rendering objects in flat color

2. Blinn-Phong shading:

3. Adding shadows:

4. Simulate reflection and refraction with specular and dielectric objects:

   Reflection	Refraction (Schlick’s approximation)

5. Beer–Lambert law

   Refraction (Schlick’s approximation)	Refraction (Schlick’s approximation + Beer's Law)

• Generate the object file:
  • mkdir build && cd build
  • cmake ..\
  • make
  • cd ../
• Execute the object file:
  • ./bin/raytracer
