Pro3D-Editor : A Progressive-Views Perspective for Consistent and
  Precise 3D Editing
Authors: name: Yang Zheng, name: Mengqi Huang, name: Nan Chen, name: Zhendong Mao

Text-guided 3D editing aims to precisely edit semantically relevant local 3D
regions, which has significant potential for various practical applications
ranging from 3D games to film production. Existing methods typically follow a
view-indiscriminate paradigm: editing 2D views indiscriminately and projecting
them back into 3D space. However, they overlook the different cross-view
interdependencies, resulting in inconsistent multi-view editing. In this study,
we argue that ideal consistent 3D editing can be achieved through a
progressive-views paradigm, which propagates editing semantics from
the editing-salient view to other editing-sparse views. Specifically, we
propose Pro3D-Editor, a novel framework, which mainly includes
Primary-view Sampler, Key-view Render, and Full-view Refiner. Primary-view
Sampler dynamically samples and edits the most editing-salient view as the
primary view. Key-view Render accurately propagates editing semantics from the
primary view to other key views through its Mixture-of-View-Experts Low-Rank
Adaption (MoVE-LoRA). Full-view Refiner edits and refines the 3D object based
on the edited multi-views. Extensive experiments demonstrate that our method
outperforms existing methods in editing accuracy and spatial consistency.
