SplatPainter: Interactive Authoring of 3D Gaussians from 2D Edits via Test-Time Training
Contributions:
-
A Novel Feedforward Editing Framework: We introduce SplatPainter, a state-aware feedforward model for the interactive and continuous editing of 3DGS. By leveraging TTT, our method iteratively incorporates user edits from 2D views, directly updating the attributes of a compact and feature-rich Gaussian representation without destructive regeneration.
-
Versatile and Intuitive Applications: We evaluate our framework on two novel and practical applications: high-fidelity local detail refinement and consistent global relighting. The unified approach provides users with precise control over both fine-grained texture details and broad appearance changes from 2D edits.
-
State-of-the-Art Performance at Interactive Speeds: Through extensive experiments, we show that SplatPainter significantly outperforms existing methods in both quality and speed. Our approach achieves superior visual results while operating at interactive rates, making it a truly practical solution for unlocking fluid, real-time creative workflows in 3D content authoring.
