About

Hi! I'm Zheng, a fourth-year Ph.D. candidate at UC Santa Barbara, working with Prof. Lingqi Yan. I earned my Master's and Bachelor's degrees from Shandong University, working with Professors Lu Wang, Yanning Xu, and remotely with Prof. Beibei Wang.

I've interned at NVIDIA with Edward Liu and at Adobe with Miloš Hašan, Valentin Deschaintre, Iliyan Georgiev, Yannick Hold-Geoffroy, Yiwei Hu, and Fujun Luan.

My research focuses on achieving real-time path tracing with ultimate photorealism, exploring geometric representations, sampling methods, complex appearance, dynamic global illumination solutions, software ray tracing solutions, and post-processing techniques.

I also study emerging technologies to enhance real-time rendering, such as compact neural networks to compress/bake code and data for efficiency and generative models for photorealism.

Misc

I enjoy optimizing my research workflow. Tools I find useful:

  • Read papers, make sense of research, and develop intuition: Heptabase.
    • My path on note-taking system: markdown + git → Notion → Obsidian → Logseq → Roam Research → Heptabase.
    • My personal opinion: note-taking is all about spatial (across different projects) and temporal (from past and for future) knowledge reuse.
  • Find related papers: Connected Papers.

I collect research self-development resources in teach-yourself-research.

Here are two renderings I made while I was taking Wei Dai’s online course; I started my rendering journey since then on.
