  We introduce ViCA-NeRF, the first view-consistency-aware method for 3D
editing with text instructions. In addition to the implicit neural radiance
field (NeRF) modeling, our key insight is to exploit two sources of
regularization that explicitly propagate the editing information across
different views, thus ensuring multi-view consistency. For geometric
regularization, we leverage the depth information derived from NeRF to
establish image correspondences between different views. For learned
regularization, we align the latent codes in the 2D diffusion model between
edited and unedited images, enabling us to edit key views and propagate the
update throughout the entire scene. Incorporating these two strategies, our
ViCA-NeRF operates in two stages. In the initial stage, we blend edits from
different views to create a preliminary 3D edit. This is followed by a second
stage of NeRF training, dedicated to further refining the scene's appearance.
Experimental results demonstrate that ViCA-NeRF provides more flexible,
efficient (3 times faster) editing with higher levels of consistency and
details, compared with the state of the art. Our code is publicly available.
