TORA framework improves 3D shape assembly with topological alignment

By PulseAugur Editorial · [1 sources] ·

Researchers have developed TORA, a novel framework for 3D shape assembly that leverages topological representation alignment. This method guides flow-matching models by distilling relational structure from pretrained 3D encoders, enhancing topological alignment through techniques like token-wise cosine matching and Centered Kernel Alignment (CKA) loss. TORA demonstrates significant improvements in convergence speed and accuracy across various benchmarks, showing particular strength in zero-shot transfer to new datasets without adding inference overhead.

    TORA: Topological Representation Alignment for 3D Shape Assembly

    arXiv:2604.04050v2 Announce Type: replace-cross Abstract: Flow-matching methods for 3D shape assembly learn point-wise velocity fields that transport parts toward assembled configurations, yet they receive no explicit guidance about which cross-part interactions should drive the …
