"Path tracing is a type of ray tracing, which means we are going to shoot a ray into the world out of every pixel. For each individual ray, we are going to see what it hits and use that information to give a color to our pixel. Doing that for every pixel independently gives us our final image.
You will be required to first build a simple raytracing engine which will be able to:
Generate a PNG image of a raytraced sphere.
Apply anti-aliasing.
Accurately simulate different types of materials like metals and dielectrics.
Mimic a real life camera and its features.

Prerequisites:
No prerequisites as such. A lot of enthusiasm and curiosity.
Tentative Timeline :
| Week | Work |
|---|---|
| Week 1 | Learn about how raytracing works and the functionalities you would be implementing. |
| Week 2 | 3D vector class. |
| Week 3 | Implementing stb_image for generating PNGs and a basic ray class. |
| Week 4 | Implementing a simple camera class and obtaining a primitive image. |
| Week 5 | Sphere class and surface normals. |
| Week 6-7 | Implement an interface for hittable objects and add support for multiple objects in a scene. |
| Week 8 | Antialiasing and materials and implement an advanced camera class. |
