This project is based on the GAMES101 homework 7 raytracer. It is my GAMES101 final project! I have integrated basic photon mapping functionality into this raytracer, and build some simple scene (these figures use SSP 1024):
Although it is not perfect, but the caustics effect is lovely!
For photon mapping:
- Trace photons to diffuse object.
- Define specular reflection and transmission material model.
- Store photons into left-balanced kd-tree photon map.
- Draw a heart! (as Valentine's Day is around XD)
- Progressive photon mapping is still pending!

Framework
- GAMES101 homework (in Chinese)
- GAMES101 framework guide (in Chinese)
-
Photon mapping
- Realistic Image Synthesis Using Photon Mapping (there is code reference, and I mainly follows this book)
- A Practical Guide to Global Illumination using Photon Maps (a summary of Realistic Image Synthesis Using Photon Mapping)
- photonmapping lecture (princeton.edu) (lecture note for photon mapping, I start from this)
- 《全局光照技术：从离线到实时渲染》(much easier than the PBR book, and in Chinese!)
- PBR book (too hard for me...)
- 光子映射总结（1/4）：基本全局光子映射（Basic Photon Mapping） - 知乎 (zhihu.com) (useful summary!)
- ... (lots of other notes form zhihu, CSDN, and github)
