GaussianEditor: A New 3D Editing Algorithm for Fast and Precise SceneModification

Beijing, China – A new 3D editing algorithm,dubbed GaussianEditor, has emerged, promising to revolutionize the way we modify and manipulate 3D scenes. Developed by researchers at Peking University, GaussianEditor leverages the power of Gaussian Splatting to enable fast and precise editing, significantly enhancing efficiency for tasks like game development and virtual reality.

What is GaussianEditor?

GaussianEditor is a 3D editing algorithm built upon the principle of Gaussian Splatting. This technique represents a 3D scene as a collection of Gaussian distributions, each representing a point or small region within the scene. These Gaussians possess attributes like position, scale, orientation, transparency, and color, enabling a flexible and efficient representation of the scene.

Key Features of GaussianEditor:

• Rapid Editing: GaussianEditor allows for swift3D scene editing, with typical editing sessions taking only 5-10 minutes.
• Gaussian Semantic Tracing: This feature utilizes semantic information to classify and track elements within the scene, providing precise control over the editing process.
• Hierarchical Gaussian Splatting (HGS): HGS isa novel Gaussian representation method that ensures stable and detailed editing results under randomized guidance.
• 3D Repair Algorithm: This specialized algorithm enables users to quickly remove unwanted objects from a scene or add new ones.
• Explicit Point Cloud Representation with Implicit Editing: GaussianEditor combines the advantages of explicit 3D pointcloud representation with implicit editing capabilities, enhancing flexibility and accuracy.

Technical Principles:

• 3D Gaussian Splatting: This technique represents a 3D scene as a series of Gaussian distributions, each representing a point or small region within the scene.
• Gaussian Semantic Tracing: By leveraging semantic segmentationtechniques, this feature projects semantic information (like object categories) from 2D images onto the 3D space, assigning semantic labels to each Gaussian point. This allows for precise control over specific elements within the scene.
• Hierarchical Gaussian Splatting (HGS): HGS applies different levels of constraintsto Gaussian points during different training stages, achieving hierarchical editing of the 3D scene. Early training stages impose strict constraints to preserve the scene’s original structure, while later stages allow for greater variation to capture details.
• 3D Repair Algorithm: When objects are removed or added to the scene, the surroundingGaussian points need to be repaired to maintain continuity and consistency. The 3D repair algorithm achieves this by recalculating and adjusting these points.
• Optimized Renderer: GaussianEditor utilizes a highly optimized renderer to render 3D scenes, ensuring high-quality and efficient rendering results.
