Software Rasterizer & Pathtracer & MeshEdit & Animation

Project Overview: 
This project was finished when I am taking Computer Graphics (Spring2024)at Carnegie Mellon University as homework . The public repository for the basic framework is here: https://github.com/CMU-Graphics/Scotty3D
Scotty3D is a 3D modeling, rendering, and animation package like Blender, but we will need to complete the main algorithms and functions of Rasterization, MeshEdit, PathTracing and Animation.
Rasterizor: 
-  Scene Graph and Transforms

-  Draw lines with the "Diamond-Exit Rule"

-  Draw triangles with the "Perspective-correct Interpolation" and "Top-left Rule"
-  Depth Testing / Mip-mapping / Supersampling

MeshEdit: 
-  Half-edge Data Structure

-  Local Operations: Split edge / Dissolve vertex...
-  Global Operation: Catmull-Clark Subdivision /Triangulation

    / Loop Subdivision...

PathTracing: 
-  Camera Ray and Intersection Test
-  Lambertian BSDF / Mirror / Refract / Glass
-  Indirect / Direct Lighting
-  Environment / Area Lighting
