RT-Splatting: Joint Reflection-Transmission Modeling with Gaussian Splatting

RT-Splatting extends 3D Gaussian Splatting by factorizing geometric occupancy from optical opacity per Gaussian, enabling simultaneous modeling of reflections and transmission on semi-transparent specular surfaces. A hybrid renderer interprets the unified representation in both surface and volume modes. Relevant to novel view synthesis pipelines involving glass, water, or other dielectric materials where prior 3DGS methods produce blurry or occluded artifacts.
