When we started out this project, we had fancy thoughts of chandeliers and castles in mind. But all fantasies must eventually end, and our dreams shattered by the awakening to reality.
As dread started to set in that the project might not be completed on time, we saw within our dread an opportunity. An oppertunity to seize that dread and share it with the world. Hence, our project model of the horrifying and the macabre, born of the fear each student faces when looking despair in the eye, was born.
However, the intent behind our model is not to scare. Carrie Fisher, who played Princess Leia in Star Wars, once said "Be afraid and do it anyway". And is that not where true courage is tested? We hope this model inspires you to face your fears, your remaining deadlines, for as we used our fear to make this model for the project, we hope you will use your fear to face yours!
We have made our scene consisting of macabre objects situated infront of a red curtain. We have utilised 3 lights. Ambient, Point and Directional.
The objects as seen are a skull, a spider, a hand, a curtain, a sphere, candles, some blood, and a table below the items. Approximately 2.5 million primitives have been used.
As can be seen, the materials are of two types, matte and reflective
We have implemented Regular Grid as an acceleration structure. To test it, we rendered images with different number of spheres, and compared the timings before and after implementing the acceleration structure. To use acceleration, add all the objects to the grid using the add_object() function, use the setup_cells() function of the grid, and then add the grid to the world using the add_geometry() function. To disable acceleration, normally add all objects to world using add_geometry() function.

We have implemented several types of lighting, namely Point, Directional and Ambient.
We have two types of cameras, parallel and perspective for different views.
We've implemented 3 samples. Simple, Random, Regular.
We've implemented Lambertian, PerfectSpecular, GlossySpecular to showcase bidirectional reflectance.
We have implemented Grid data structure for quick intersection of rays and primitives.
We have implemented several geometric structures such as Planes, Spheres, Triangles and Rectangle as well. We also implemented Compound Objects for the purpose of regular Grid.
We have implemented several materials in our renders. These are Matt, Phong, Reflective and Emissive.
We have implemented several tracers alongside Basic and Raycast such as AreaLighting and Whitted.
We would like to thank the following sources for their immeasureable help and usefulness during the project:
1. Kevin Suffern - RayTracing from the Ground Up
2. For reading ply files: hapPLY
3. 3D models from: sketchfab, cgtrader, clara.io
4. Blender
