GaussianEditor - a 3D editing algorithm that supports fast and precise modification of 3D scenes.

What is GaussianEditor?

GaussianEditor is a 3D editing algorithm based on Gaussian Splatting, allowing users to quickly and accurately modify 3D scenes. Through Gaussian semantic tracking and layered Gaussian Splatting, it provides high editing control and stability while maintaining rendering quality. The editing process typically 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.

GaussianEditor's main functions

• Quick EditIt provides fast 3D scene editing capabilities, with a single editing session typically taking only 5-10 minutes.
• Gaussian Semantic TrackingBy classifying and tracking elements in a scene using semantic information, more precise editing control can be achieved.
• Layered Gaussian Splash (HGS)A novel Gaussian representation method that can stably achieve fine editing results under random generation guidance.
• 3D Repair AlgorithmA specially designed algorithm that allows users to quickly delete unwanted objects or add new objects to a scene.
• Explicit point cloud representation and implicit editingIt combines explicit 3D point cloud representation with implicit editing capabilities, improving the flexibility and accuracy of editing.

The technical principles of GaussianEditor

• 3D Gaussian Splatting:A 3D scene representation technique that decomposes a scene into a series of Gaussian distributions. Each Gaussian represents a point or small region in the scene and has attributes such as position, scale, orientation, transparency, and color.
• Gaussian Semantic Tracing:based onSemantic segmentation technology projects semantic information (such as object categories) from 2D images back onto Gaussian points in 3D space, assigning semantic labels to each Gaussian point, thereby enabling precise control over specific elements in the scene.
• Hierarchical Gaussian Splatting (HGS):By imposing varying degrees of constraints on Gaussian points at different training stages, layered editing of 3D scenes was achieved. In the early training stages, Gaussian points were strictly constrained to maintain the original structure of the scene, while in the later training stages, more variation was allowed to capture details.
• 3D Repair Algorithm:When objects are removed from or added to a scene, the surrounding Gaussian points need to be repaired to maintain the scene's continuity and consistency. 3D inpainting algorithms achieve this by recalculating and adjusting the Gaussian points.
• Optimized renderer:GaussianEditor uses a highly optimized renderer to render 3D scenes, ensuring both the quality and efficiency of the rendering results.
