TranSplat: Instant Object Relighting in Gaussian Splatting via Spherical Harmonic Radiance Transfer
Boyang Tony Yu, Yanlin Jin, Yun He +3
We present TranSplat, a method for instant, accurate object relighting within the Gaussian Splatting (GS) framework. Rather than relying on costly inverse rendering routines, we pr…
Learning 3D Reconstruction with Priors in Test Time
Lei Zhou, Haoyu Wu, Akshat Dave +1
We introduce a test-time framework for multiview Transformers (MVTs) that incorporates priors (e.g., camera poses, intrinsics, and depth) to improve 3D tasks without retraining or…
Poppy: Polarization-based Plug-and-Play Guidance for Enhancing Monocular Normal Estimation
Irene Kim, Sai Tanmay Reddy Chakkera, Alexandros Graikos +2
Monocular surface normal estimators trained on large-scale RGB-normal data often perform poorly in the edge cases of reflective, textureless, and dark surfaces. Polarization encode…
Embedding Physical Reasoning into Diffusion-Based Shadow Generation
Shilin Hu, Jingyi Xu, Akshat Dave +2
Generating realistic shadows for inserted objects requires reasoning about scene geometry and illumination. However, most existing methods operate purely in image space, leaving th…
