Reflections from shiny objects and glass facades naturally extend the field of view of a camera, capturing the surrounding environment without the need to pan the camera or acquire a full panorama. We propose PanoLess, a Gaussian-splat-based framework that reconstructs the surrounding environment as a distant illumination map from images captured on only one side of a reflective surface.

Abstract: We revisit the role of appearance modeling in 3D Gaussian Splatting (3DGS) and show that limited expressiveness in view-dependent reflectance is a key...

The paper introduces Reflection-aware Gaussian Splatting (RGS), a physically-based deferred rendering framework that improves novel view synthesis for reflective objects. RGS leverages a powerful 3D foundation model to provide a strong geometric prior and employs cross-view shape consistency regularization to prevent surface collapse and reduce geometric hollows. Additionally, a reflection-aware densification strategy captures specular variations across views, resulting in higher-quality renderings of reflective objects.

GraftRay is a method for inserting mesh objects into scenes reconstructed with 2D or 3D Gaussian splatting, ensuring physically consistent lighting and shadows. It recovers scene materials and normals using diffusion priors, models spatially‑extended emitters in closed form, and employs a hybrid renderer that path‑traces both Gaussians and meshes to produce view‑consistent shading, interreflections, and soft shadows. On the FIPT benchmark, GraftRay achieves state‑of‑the‑art rendering fidelity and shadow accuracy while remaining competitive in rendering efficiency.
