[Suggestion] Acknowledging UCGM in both Code and Technical Report (as referenced in Saining Xie et al.)

[sp12138]

Hello @SkyworkAI-Team,

Thanks for the great work on UniPic!

While going through the code, I noticed that the implementation of the Finite Difference technique in train_cm_dmd.py shares the same logic and specific variable naming as the UCGM repository.

UniPic: train_cm_dmd.py (L79-L88)

UCGM: unigen.py (L278-L291)

Since this technique is widely recognized as originating from UCGM, other recent works (e.g., Saining Xie et al. in arXiv:2601.09881) have explicitly cited it when using the same method.

To align with these community standards, I have two kind suggestions:

• Add a code comment: It would be helpful to mark the source in the code (e.g., # Adapted from UCGM: https://github.com/LINs-lab/UCGM) so future developers know where this technique comes from.

• Update References: Consider adding UCGM to the reference list in the README or Technical Report to acknowledge their contribution.

Hope this is helpful for refining the project!
