We propose a method for editing 3D Gaussian Splatting (3DGS) scenes with text-instructions. Given a 3DGS scene of a scene and the - collection - of images used to reconstruct it, our method uses an image-conditioned diffusion model (InstructPix2Pix) to iteratively edit the input images while optimizing the underlying scene, resulting in an optimized 3D - scene that - respects the edit instruction. We demonstrate that our proposed method is able to edit large-scale, - real-world - scenes, and is able to accomplish more realistic, targeted edits than prior work. + scene that respects the edit instruction. We demonstrate that our proposed method is able to edit large-scale, + real-world scenes, and is able to accomplish realistic and targeted edits.
