Conclusions and Future Works, Acknowledgements and References 5.4. Single View Reconstruction We evaluate the quality of the reconstructed geometry of different methods. The quantitative results are summarized in Table 1, and the qualitative comparisons are presented in Fig. 6. Shap-E [25] tends to produce incomplete and distorted meshes. SyncDreamer [33] generates shapes that are roughly aligned with the input image but lack detailed geometries, and the texture quality is subpar. One-2-3- 45 [30] attempts to reconstruct meshes from the multiviewinconsistent outputs of Zero123 [31]. While it can capture coarse geometries, it loses important details in the process. In comparison, our method stands out by achieving the highest reconstruction quality, both in terms of geometry and textures. This paper is available on arxiv under CC BY-NC-ND 4.0 DEED license.
