GaussCtrl: Multi-View Consistent Text-Driven 3D Gaussian Splatting Editing (2403.08733v4)

Abstract: We propose GaussCtrl, a text-driven method to edit a 3D scene reconstructed by the 3D Gaussian Splatting (3DGS). Our method first renders a collection of images by using the 3DGS and edits them by using a pre-trained 2D diffusion model (ControlNet) based on the input prompt, which is then used to optimise the 3D model. Our key contribution is multi-view consistent editing, which enables editing all images together instead of iteratively editing one image while updating the 3D model as in previous works. It leads to faster editing as well as higher visual quality. This is achieved by the two terms: (a) depth-conditioned editing that enforces geometric consistency across multi-view images by leveraging naturally consistent depth maps. (b) attention-based latent code alignment that unifies the appearance of edited images by conditioning their editing to several reference views through self and cross-view attention between images' latent representations. Experiments demonstrate that our method achieves faster editing and better visual results than previous state-of-the-art methods.

Multi-View Consistent Text-Driven 3D Gaussian Splatting Editing: A Comparative Study

Introduction

In the pursuit of advancing 3D scene editing capabilities, the paper presents a comprehensive analysis and qualitative comparisons of the proposed method, GaussCtrl, with existing baseline methods in text-driven 3D Gaussian splatting editing. This methodology aims to offer enhanced consistency and quality in multi-view 3D scene reconstructions, focusing on both 360-degree and forward-facing scenes across various subjects such as stone sculptures and human faces.

Methodology Overview

The essence of this work lies in the application of Gaussian splatting techniques, manipulated through text inputs to control and edit 3D scenes in a manner that maintains high-level consistency across multiple views. The approach is distinct in its ability to seamlessly integrate textual commands into the editing process, allowing for intuitive and precise modifications of 3D objects and scenes.

Key Findings and Comparisons

The comprehensive qualitative analysis provided in the paper showcases the significant enhancements achieved by GaussCtrl over baseline methods, particularly in maintaining multi-view consistency during text-driven edits. The findings from the paper are supported by visual evidence across a range of subjects:

• 360-degree Scenes: The method was tested on objects such as a bear statue, a dinosaur, and a stone horse. Results demonstrate superior preservation of geometric consistency and texture quality across all angles when compared to baselines.
• Forward-facing Scenes: Human faces and objects viewed from a forward-facing perspective were also analyzed. GaussCtrl showed remarkable ability in keeping facial features and object details coherent in response to text edits, outperforming traditional approaches.

Implications and Speculations on Future Developments

The paper's findings have profound implications for the development of 3D scene editing tools, particularly those relying on natural language input for artistic or practical modifications. The demonstrated effectiveness of text-driven 3D Gaussian splatting editing opens avenues for more intuitive interfaces in 3D modeling and virtual environment design, potentially lowering the barrier to entry for non-specialists.

Speculatively, the integration of more advanced NLP capabilities could further streamline the interaction process, making it possible to execute more complex edits with simple text commands. Additionally, the exploration of real-time editing frameworks could significantly enhance user experience, allowing for immediate visual feedback and iterative design processes.

Conclusion

The research presented offers a critical advancement in text-driven 3D scene editing, with GaussCtrl providing a robust framework for multi-view consistent modifications. By leveraging Gaussian splatting techniques aligned with textual inputs, the method opens new possibilities for efficient and intuitive 3D editing. As technology progresses, it is anticipated that these methodologies will further evolve, potentially incorporating more sophisticated AI-driven approaches to understand and execute complex editing tasks with unprecedented precision and flexibility.
