Gaussian Splatting with Reflections Guided by What is Seen

Key points

• Existing methods utilize environment maps, which only represent lights from infinity, or environment Gaussians, which rely solely on indirect supervision from reflections, are insufficient for accurately modeling such effects.1
• Here, we propose a framework based on 2D Gaussian Splatting (2DGS) that leverages directly observable environment information in input images.1
• Our approach also integrates a hybrid reflection appearance representation and view-dependent specular modeling.1
• Experiments on public benchmarks and a newly curated near-field reflection dataset demonstrate that our method achieves superior rendering quality and geometric accuracy.1

  While novel view synthesis methods like Neural Radiance Fields (NeRF) and 3D Gaussian Splatting (3DGS) have shown impressive performance on common scenes, they often struggle with capturing view-dependent specular effects, particularly near-field reflections.

  Existing methods utilize environment maps, which only represent lights from infinity, or environment Gaussians, which rely solely on indirect supervision from reflections, are insufficient for accurately modeling such effects.
