Abstract

We introduce ReplaceAnything3D model (RAM3D), a novel text-guided 3D scene editing method that enables the replacement of specific objects within a scene. Given multiview images of a scene, a text prompt describing the object to replace, and text prompt describing the new object, our Erase-and-Replace approach can effectively swap objects in the scene with newly generated content while maintaining 3D consistency across multiple viewpoints. We demonstrate the versatility of ReplaceAnything3D by applying it to various realistic 3D scenes, showcasing results of modified foreground objects that are well-integrated with the rest of the scene without affecting its overall integrity.

Method

We distill a pretrained inpainting Latent Diffusion Model over 3 stages

  • Erase stage: remove the masked objects and fill in the background
  • Replace stage: generate new objects and composite them to the inpainted background scene
  • Finally: train a new NeRF using the edited scene images
