CVPR 2026 ·Website ·Code ·Data

We develop a lightweight adaptation scheme for 3D foundation models that enables robust geometric reasoning under extreme-view scenarios by updating only a small subset of bias parameters, achieving state-of-the-art performance on relative rotation estimation.

ARSplat: Mobile AR for Time-Lapse Tour

Yiwen Zhang, Nhan Tran, Abe Davis

Research Project

Leveraging iPhone's LiDAR camera, this project builds an App that captures and aligns multiple scenes of a changing environment, then visualizes the time-lapse.

Auto-Riggable Gaussian Characters

Course Project·GitHub

Leveraging dynamic gaussian splats with local rigidity constraints, this project decomposes moving subjects into animation-ready rigs.

MLS-MPM and CPIC

Course Project·GitHub

This project implements the Moving Least Squared Material Point Method, CPIC, various materials, and mesh extraction in 2D and 3D.

Compositional Splatting for Construction Sites

Course Project·Project Paper

Leveraging gaussian splats for digital twin capture on construction sites, this project aims to simulate realistic construction environments and record the construction processes.

Zelda: Catch the Koroks

Course Project ·Project Paper ·Project Video

This project uses rasterization to render a mini game that is inspired by Zelda. Customized shaders are created to simulate grass, trees, terrain, etc.

Apple Is All You Need

Course Project·Project Paper

This project implements a raytracer that renders a scene exclusively composed of apples. Various graphics techniques are used including constructive solid geometry, Fresnel refraction, defocus blur, etc.
