3D Gaussian splatting (3DGS) rwzi nieuwveer

3D Gaussian splatting (3DGS) is a rasterization-based technique used in the field of real-time radiance fields for representing and rendering photorealistic 3d scenes from a sparse set of 2D images.[6][4] It enables the creation of high-quality real-time novel-view scenes by combining multiple photos or videos, addressing a significant challenge in the field.

The method represents scenes with 3D Gaussians that retain properties of continuous volumetric radiance fields, integrating sparse points produced during camera calibration. It introduces an anisotropic representation using 3D Gaussians to model radiance fields, along with an interleaved optimization and density control of the Gaussians. A fast visibility-aware rendering algorithm supporting anisotropic splatting is also proposed, catering to GPU usage.[4]
