MeshLoom: Feed-Forward Non-Rigid Registration of Mesh Sequences
Summary
MeshLoom is a novel feed-forward registration network designed to directly reconstruct vertex deformations across mesh sequences. This approach significantly advances non-rigid registration by overcoming limitations of existing models, which often involve costly per-instance optimization, narrow object categories, or pairwise-only inputs. MeshLoom is highly efficient, registering multiple meshes within seconds. Its core features include a topology-aware point representation that encodes the anchor mesh's topology into per-vertex features, and a multi-modal encoder that fuses this representation with frame-specific cues like shape latents and image features. A lightweight decoder then queries the resulting global motion embedding to retrieve per-vertex deformations, enabling state-of-the-art results and extending capabilities to motion interpolation and mesh morphing.
Key takeaway
For 3D graphics developers or computer vision engineers working with dynamic mesh sequences, MeshLoom offers a compelling alternative to traditional, often costly, per-instance optimization methods. You can achieve state-of-the-art non-rigid registration results rapidly, processing multiple meshes in seconds. Consider integrating this feed-forward network to enhance efficiency and unlock new capabilities like seamless motion interpolation and mesh morphing in your applications.
Key insights
MeshLoom uses a feed-forward network with topology-aware encoding and multi-modal fusion for efficient non-rigid mesh sequence registration and interpolation.
Principles
- Topology-aware encoding improves geometry understanding.
- Multi-modal fusion captures dense inter-frame correspondence.
- Global embedding enables intermediate timestamp generation.
Method
Encode anchor mesh topology into per-vertex features. Fuse with frame cues via a multi-modal encoder to create a compact global motion embedding. Query this embedding with anchor-mesh representation for per-vertex deformations.
