FurE: 10x Faster 3D Animal Fur Reconstruction Without Animal Datasets
The 30-second version

Reconstructing realistic and editable animal fur from multi-view images is difficult due to self-occlusion and a lack of dedicated animal fur datasets. FurE overcomes this by optimizing a root-conditioned latent field decoded via a PCA decoder learned from human hair data. It reconstructs the underlying defurred animal body using a surface-constrained Gaussian Frosting representation and part-based priors. This approach generalizes across synthetic and real-world sequences, achieving a 10x training speedup over state-of-the-art dense per-strand optimization methods.

Key points

01

Zero Animal Datasets

Innovatively utilizes a PCA decoder learned from human-hair strand data, bypassing the extreme scarcity of dedicated animal fur datasets.

02

10x Training Speedup

Achieves a 10x speedup in strand training compared to current SOTA dense per-strand optimization while preserving fine details.

03

Gaussian Frosting Defurring

Reconstructs the hidden, defurred animal body by leveraging local fur-thickness cues from a surface-constrained Gaussian Frosting representation.

04

Highly Editable Groom

Recovers a per-strand, highly editable groom, enabling fine-grained adjustments for artists and animators.

Why it matters

Traditional 3D animal reconstruction often bypasses editable fur due to extreme data scarcity. FurE demonstrates that human-hair models can successfully transfer to animal fur, eliminating the need for expensive animal datasets. This is highly impactful for VFX, gaming, and VR, allowing artists to generate physics-ready, animatable grooms from simple multi-view images with a 10x speedup.

How to use it

  1. 1Realistic animal 3D modeling and groom rigging for VFX and gaming.
  2. 2Rapid creation of interactive digital pets from real-world photos for VR and metaverse applications.

Limitations & caveats

  • Relies on a PCA decoder trained on human hair, which may struggle to reconstruct extremely exotic or non-human-like animal fur structures.
  • Requires multi-view image inputs, which remains challenging for single-image reconstruction or highly dynamic sequences with motion blur.
