Gaussian Splatting
A real-time rendering technique that represents scenes using three-dimensional Gaussian distributions. By optimizing the position, shape, and appearance attributes of large numbers of Gaussian ellipsoids in 3D space, it achieves high-quality, high-efficiency novel view synthesis. The technique is commonly applied in 3D content creation and scene reconstruction.

Timeline (last 90 days)
In scenes where the active light source is rigidly attached to the camera, neural rendering methods (such as NeRF and Gaussian splatting) incorrectly encode view-dependent lighting as surface color, causing appearance inconsistency and hindering geometry and albedo recovery.
Gaussian splatting represents scene geometry and appearance using a large number of 3D Gaussian ellipsoids and renders them via differentiable rasterization, typically achieving rendering speeds orders of magnitude faster than NeRF.
When training the splat, the central input image can be at a higher resolution than the video frames, thereby preserving more detail in the final reconstruction.
Gaussian splatting is a 3D scene representation method proposed by Kerbl et al. at SIGGRAPH 2023, representing scenes using 3D Gaussian ellipsoids with position, color, opacity, and shape parameters.
Video generation models only guarantee visual plausibility of frames and do not guarantee geometric/physical consistency across frames, causing splat training to generate floating noisy Gaussian blobs (garbage data) in inconsistent regions.
The entire pipeline from a single image to Gaussian splatting can be completed using a GPU with 12GB of VRAM.
When generating video, the starting frame and ending frame must use the same image in order to force the model to generate a closed 360-degree orbit trajectory.
Compared to NeRF, 3DGS training is several to more than ten times faster, real-time rendering frame rates can reach tens to hundreds of FPS, and scenes can be directly exported as point cloud assets.
