Question about SH coefficient initialization implementation

Hi, thank you for releasing the code to this awesome work!

I was reading Sec. 3.5 of the paper, where it is stated that the initial spherical harmonics coefficients are estimated for each sampled Gaussian by collecting RGB observations from multiple views and solving a linear least-squares system.

However, while looking through the current repository, I could not find this SH initialization step. In source/corr_init.py, it seems that the initial color is assigned to the DC component using the reference image color, while the remaining SH coefficients are initialized to zero.

Could you clarify whether the SH coefficient initialization described in Sec. 3.5 is currently implemented somewhere else in the repository, or whether it is omitted from the current public release? If it is omitted, is this planned to be included in a future code update?

Thank you again for your work and for making the code available!

Read Sec. 3.5 of the paper and inspect source/corr_init.py, especially the initialization of the DC and remaining spherical harmonics coefficients. Search the repository for other SH initialization code and compare it with the described multi-view least-squares procedure. Done means determining whether the procedure exists elsewhere, is omitted from the release, or has a stated future-update plan.
