Key points
- It optimizes 3DGS directly in pixel space through differentiable rendering without VAE or RAE, eliminating information loss.
- It unifies generation and reconstruction in a single forward pass by splitting views into clean and noisy subsets.
- The geometry perception loss provides geometric supervision in the feature space of a 3D foundation model.
- It outperforms existing latent-space generation methods on RealEstate10K, DL3DV-10K, and WorldScore, while matching state-of-the-art reconstruction quality.
- Removing the geometry perception loss causes a 1.13 dB drop in PSNR and a 12.5 percent relative drop in AUC@5, confirming its effectiveness.
