What is GaussianEditor
GaussianEditor is a 3D editing algorithm based on Gaussian Splatting that supports users in quickly and precisely modifying 3D scenes. Through Gaussian semantic tracing and hierarchical Gaussian Splatting, it provides a high degree of editing control and stability while maintaining rendering quality. The editing process usually takes only 5-10 minutes, significantly improving the efficiency of 3D editing. This technology is particularly suitable for fields such as game development and virtual reality, and has broad application prospects.
Main features of GaussianEditor
- Fast editing: Provides fast 3D scene editing capabilities, with a single editing session usually taking only 5-10 minutes.
- Gaussian semantic tracing: Classifies and tracks elements in the scene through semantic information, enabling more precise editing control.
- Hierarchical Gaussian Splatting (HGS): A new Gaussian representation method that can stably achieve fine editing results under random generation guidance.
- 3D inpainting algorithm: A specially designed algorithm that allows users to quickly delete unwanted objects from the scene or add new objects.
- Explicit point cloud representation and implicit editing: Combines explicit 3D point cloud representation with implicit editing capabilities, improving the flexibility and accuracy of editing.
Technical principles of GaussianEditor
- 3D Gaussian Splatting：A 3D scene representation technique that represents a scene by decomposing it into a series of Gaussian distributions. Each Gaussian represents a point or small region in the scene, with attributes such as position, scale, orientation, opacity, and color.
- Gaussian Semantic Tracing: Based onsemantic segmentation technology, semantic information in 2D images (such as object categories) is back-projected onto Gaussian points in 3D space, assigning a semantic label to each Gaussian point, thereby achieving precise control over specific elements in the scene.
- Hierarchical Gaussian Splatting (HGS)：By applying different degrees of constraints to Gaussian points at different training stages, hierarchical editing of 3D scenes is achieved. Gaussian points in the early training stage are strictly constrained to preserve the original structure of the scene, while Gaussian points in the later training stage allow more variation to capture details.
- 3D inpainting algorithm：When objects are deleted from or added to the scene, the surrounding Gaussian points need to be inpainted to maintain the continuity and consistency of the scene. The 3D inpainting algorithm achieves this goal by recalculating and adjusting Gaussian points.
- Optimized renderer：GaussianEditor uses a highly optimized renderer to render 3D scenes, ensuring the quality and efficiency of the rendering results.
