Query: Editing Conditional Radiance Fields   A neural radiance field (NeRF) is a scene model supporting high-quality view
synthesis, optimized per scene. In this paper, we explore enabling user editing
of a category-level NeRF - also known as a conditional radiance field - trained
on a shape category. Specifically, we introduce a method for propagating coarse
2D user scribbles to the 3D space, to modify the color or shape of a local
region. First, we propose a conditional radiance field that incorporates new
modular network components, including a shape branch that is shared across
object instances. Observing multiple instances of the same category, our model
learns underlying part semantics without any supervision, thereby allowing the
propagation of coarse 2D user scribbles to the entire 3D region (e.g., chair
seat). Next, we propose a hybrid network update strategy that targets specific
network components, which balances efficiency and accuracy. During user
interaction, we formulate an optimization problem that both satisfies the
user's constraints and preserves the original object structure. We demonstrate
our approach on various editing tasks over three shape datasets and show that
it outperforms prior neural editing approaches. Finally, we edit the appearance
and shape of a real photograph and show that the edit propagates to
extrapolated novel views.
