Bio

    I am currently a PhD student at the Center for Visual Computing at UC San Diego, advised by professor Ravi Ramamoorthi and also working with professor Tzu-Mao Li. My research primarily focuses on physically based rendering, especially forward&inverse light transport simulation and sampling problems. Previously, I obtained my bachelor's degree in CS from the University of Hong Kong and worked a bit on knowledge-based question answering systems.

    I have had the fortune to intern at Adobe Graphics Research and Meta Reality Labs for the past couple of summers, working with amazing mentors and colleagues. Most recently, I'm interning at NVIDIA RTR with Marco Salvi and other wonderful mentors.

    Before PhD, I worked as a rendering research engineer at ZJU-Manycore Tech joint Lab of CG&AI, led by Dr. Rui Tang and Prof. Rui Wang, where I mainly worked on our self-developed Render Engine FF (aka fast and furious :P), Monte Carlo sampling, denoising and other graphics related topics. During the interest exploration phase of my undergraduate, I spent half a year in freezing Ottawa, Canada, working on unified model language, and also spent a short time at Alibaba and Sensetime on stream processing and face recognition, respectively.

Research

I am mainly interested in physically-based rendering and real-time graphics, especially light transport simulation, stochastic sampling, learning approaches for appearance modelling and data-prior boosted light transport in general. Recently I'm very interested in optimization problems and 3D learning.

    Residual Path Integrals for Re-Rendering

    project page / paper / code (coming)

    Incremental re-rendering of scenes in a common senario where only a small portion is moving or edited (e.g. the main character hanging around in an open world).
    Formulating the difference between two frames as a (correlated) light-transport integral. Devising sampling strategies to focus on paths with non-zero residual-radiance contribution and tailoring appropriate path mappings.
    We welcome increased attention to the exploration and potential optimization of the residual path integral and, overall, the re-rendering problem.

Gallery

, if it can be called A Gallery.... I do some drawing and painting when I'm struggling with research. I might stop doing research once my paintings start making money - you know, the best-case scenario I can think of, after the painter's death.

These photos were taken randomly so the resolution may not be good.

Miscellany

    I play some soccer with our community amateur team when the sun is not too bright (what does this mean in San Diego?).

Yes. The La Jolla beach you can't escape from in SD.

Interested keywords: Light transport simulation; Importance sampling; Rendering; Numerical optimization.
E-mail me to chat. I welcome collobrations related to those problems. :P

NO NEWS IS GOOD NEWS

  • 09/30/2024 - Even more sad. Antoine Griezmann retired from the national team. I've only ever bought the jerseys of three players: Griezmann, Pogba and De Bruyne.
  • 07/06/2024 - Toni Kroos hung up his boots. Sadly.
  • 06/2024 - Started internship at Nvidia RTR
  • 06/02/2024 - Updated the website with a new bg color.. Good for you if you find it ugly
  • 06/01/2024 - Real Madrid won their 15th UCL trophy.. Can u believe Modric will stay for another season
  • 04/05/2024 - 30 years since Kurt Cobain died..
  • I don't need a news column if I don't have much news right..

Do we have to use X ?

By putting it here, I'm trying to force myself to use Tweeter (X) to follow new research..... Here are tweets if I ever tweet.
