Project 3: Hongyi Ding

[JohnnySIST]

Repo Link: Project3-CUDA-Path-Tracer

Core Features Completed

• Shading kernel with BSDF evaluation (diffuse, perfect specular surfaces)
• Stream compacted path termination
• Sorting by material type
• Stochastic sampled antialiasing

Extended Features Completed

• Visual Improvements
  • 2️⃣​ Refraction with Frensel effects
• Mesh Improvements
  • 4️⃣​ Arbitrary mesh loading and rendering (glTF)
• Performance Improvements
  • 1️⃣​ Russian roulette
  • 6️⃣​ Hierarchical spatial data structures

Other Features and Details

• For specular materials, I've included both refraction and reflection
• I used tinygltf to parse gltf formats
• The termination rate for Russian roulette is 0.9 by default
• I used BVH to accelerate the intersection test

README Completion Checklist

• Cover image in readme does not use Cornell Box
• Descriptions, screenshots, debug images, side-by-side comparisons of features implemented
• Analysis
• Scenes and meshes included or linked
• Third-party library changes or compilation changes documented
• Bloopers (optional)
