Universal Beta Splatting
Rong Liu, Zhongpai Gao, Benjamin Planche, Meida Chen, Van Nguyen Nguyen, Meng Zheng, Anwesa Choudhuri, Terrence Chen, Yue Wang, Andrew Feng, Ziyan Wu
ICLR 2026
Universal Beta Splatting generalizes 3D Gaussian Splatting to N-dimensional anisotropic Beta kernels, enabling controllable dependency modeling across spatial, angular, and temporal dimensions within a single representation.
Splat Feature Solver
Butian Xiong, Rong Liu, Kenneth Xu, Meida Chen, Andrew Feng
ICLR 2026
A unified, kernel- and feature-agnostic framework that formulates feature lifting as a sparse linear inverse problem, enabling efficient closed-form solutions with high-quality 3D semantic features.
Deformable Beta Splatting
Rong Liu*, Dylan Sun*, Meida Chen, Yue Wang†, Andrew Feng†
SIGGRAPH 2025
Deformable Beta Splatting introduces deformable Beta Kernels with adaptive frequency control for both geometry and color encoding, capturing complex geometries and lighting while only using 45% parameters and rendering 1.5x faster than 3DGS-MCMC.
SplatMAP: Online Dense Monocular SLAM with 3D Gaussian Splatting
Yue Hu, Rong Liu, Meida Chen, Peter Beerel, Andrew Feng
I3D 2025
A real-time monocular SLAM system that fuses 3D Gaussian Splatting with SLAM’s dynamic depth and pose updates via SLAM-Informed Adaptive Densification and Geometry-Guided Optimization.
AtomGS: Atomizing Gaussian Splatting for High-Fidelity Radiance Field
Rong Liu, Rui Xu, Yue Hu, Meida Chen, Andrew Feng
BMVC 2024
AtomGS proposes an atomized proliferation of Gaussians and edge-aware normal loss to refine Gaussian splatting, boosting geometric precision and rendering fidelity in novel-view synthesis.
