Key points

  • It directly represents meshes as triangle soup, avoiding the limitations of autoregressive serialization such as slow speed and error accumulation.
  • It designs an Equivariant DiT architecture that preserves both face permutation invariance and vertex cyclic invariance.
  • It introduces a coupling loss based on nested optimal transport that removes learning signals that violate symmetry.
  • It achieves the best 1-NNA on three of the four ShapeNet categories and matches the quality of state-of-the-art autoregressive models.
  • It speeds up inference by 18.55x, enabling sub-second mesh generation compared with autoregressive methods.
  • A post-processing denoiser reduces self-intersection rate, Ri, by about 56% with negligible additional latency.
