Gaussian Splatting
A 3D reconstruction and rendering method that explicitly represents a scene with a large number of 3D Gaussian primitives carrying position, covariance, color and opacity. It renders far faster than NeRF while maintaining comparable visual quality, and has become one of the mainstream representations for real-time 3D scene reconstruction.
Timeline (last 90 days)
In the scene description graph approach, the LLM generates a structured scene graph (object list plus positional relationships), which is then handed to a dedicated 3D generation module (such as methods based on NeRF or Gaussian Splatting) to complete rendering.
Gaussian Splatting can render tens or even hundreds of times faster than NeRF while maintaining similar visual quality.
A Reddit creator shared a workflow for shooting 360-degree orbit shots using the AI video generation tool Minimax, then using COLMAP for camera pose estimation, and finally importing the result into Gaussian Splatting software to generate a 3D model.
The Gaussian Splatting algorithm requires camera poses output by COLMAP as initialization data in order to correctly optimize the position and appearance of Gaussian ellipsoids in three-dimensional space.
It is recommended to start with simple, evenly lit, texture-rich subjects, and to strictly enforce the same-image first-and-last-frame setting for best reconstruction results.
The industry narrows the sim-to-real gap through means such as domain randomization, neural rendering simulation scenes reconstructed from real data (e.g., NeRF/Gaussian Splatting), and adversarial scene generation.
