Advances in 4D Representation: Geometry, Motion, and Interaction
Mingrui Zhao, Sauradip Nag, Kai Wang +5
We present a survey on 4D generation and reconstruction, a fast-evolving subfield of computer graphics whose developments have been propelled by recent advances in neural fields, g…
Articulate That Object Part (ATOP): 3D Part Articulation via Text and Motion Personalization
Aditya Vora, Sauradip Nag, Kai Wang +1
We present ATOP (Articulate That Object Part), a novel few-shot method based on motion personalization to articulate a static 3D object with respect to a part and its motion as pre…
Hierarchical Transformers for Unsupervised 3D Shape Abstraction
Aditya Vora, Lily Goli, Andrea Tagliasacchi +1
We introduce HiT, a novel hierarchical neural field representation for 3D shapes that learns general hierarchies in a coarse-to-fine manner across different shape categories in an…
ASIA: Adaptive 3D Segmentation using Few Image Annotations
Sai Raj Kishore Perla, Aditya Vora, Sauradip Nag +2
We introduce ASIA (Adaptive 3D Segmentation using few Image Annotations), a novel framework that enables segmentation of possibly non-semantic and non-text-describable "parts" in 3…
