Question about exporting PLY File for better visualization

[Eisoc]

Hi !
I followed the guidelines very well and ran the code on some waymo datasets and was very shocked at the results. For better visualization, I think, exporting to ply is very good. And I see that you have already written this function.

drivestudio/utils/misc.py

Line 50 in 388642a

def export_gaussians_to_ply(model, path, name='point_cloud.ply', aabb=None):

I would like to know, does this function require the incoming models to be trainer.models.values(), and if so, maybe we have to put some getters inside the Gaussian model, such as vanilla, in order to read attributes such as self._means.

Hi @Eisoc, sorry for the late response!

Yes, this function requires the input models to be trainer.models.values().

I've implemented some export_gaussians_to_ply functions in both misc.py and some Gaussian model files. These were used when I was debugging the code, and I haven't modified them to export standard .ply yet.

I saw your PR, I'll look into it today, thanks for the contribution!
