Offline3 : Implementation-of-Ray-Tracing

---

This project implements the following :

• A fully controllable camera : camera moves in all directions by pressing different keys.
• Creates plane and shapes of different structure: takes input from a file and draws spheres, triangle, quadric surface, Pyramids and a floor(2d plane).
• Illumination with the Phong Lighting Model : computes the ambient, specular and diffuse component of each object and light them accordingly.
• Recursive Reflection : reflection is computed recursively for an object according to the variable recursion_level.
• Snapshot : A snapshot can be taken pressing "0" button
• Texture : Texture can be added in the floor pressing "space" button. Otherwise, floor will be without texture in the snapshot.
