Mesh-Driven 3D Gaussian Splat Manipulation

Companion Proceedings of the Symposium on Interactive 3D Graphics and Games
Manipulating 3D Gaussian Splatting (3DGS) models currently lacks the flexibility of traditional mesh workflows as existing tools require costly retraining or are simply too restrictive. We present a realtime manipulation pipeline that enables mesh-driven editing for arbitrary pre-trained 3DGS models without re-optimization.

PCGS: Progressive Compression of 3D Gaussian Splatting

Proceedings of the AAAI Conference on Artificial Intelligence
3D Gaussian Splatting (3DGS) achieves impressive rendering fidelity and speed for novel view synthesis. However, its substantial data size poses a significant challenge for practical applications. While many compression techniques have been proposed, they fail to efficiently utilize existing bitstreams in on-demand applications due to their lack of ...

Gaussian in the Wild: 3D Gaussian Splatting for Unconstrained Image Collections

Novel view synthesis from unconstrained in-the-wild images remains a meaningful but challenging task. The photometric variation and transient occluders in those unconstrained images make it difficult to reconstruct the original scene accurately. Previous approaches tackle the problem by introducing a global appearance feature in Neural Radiance Fields (

LiDAR-enhanced 3D Gaussian Splatting Mapping

2025 IEEE International Conference on Robotics and Automation (ICRA)
This paper introduces LiGSM, a novel LiDAR-enhanced 3D Gaussian Splatting (3DGS) mapping framework that improves the accuracy and robustness of 3D scene mapping by integrating LiDAR data. LiGSM constructs joint loss from images and LiDAR point clouds to estimate the poses and optimize their extrinsic parameters, enabling dynamic adaptation to ...

Flash-Splat: 3D Reflection Removal with Flash Cues and Gaussian Splats

We introduce a simple yet effective approach for separating transmitted and reflected light. Our key insight is that the powerful novel view synthesis capabilities provided by modern inverse rendering methods (e.g.,~3D Gaussian splatting) allow one to perform flash/no-flash reflection separation using unpaired measurements -- this relaxation ...
