Some questions about citygsv2 training

[qqa111]

1、When performing the Finetune model parallel and merge steps, the merged result is a checkpoint， How to generate a ply？
2、In Mesh extraction and evaluation step, python utils/gs2d_mesh_extraction.py
outputs/$NAME
--voxel_size $VOXEL_SIZE
--sdf_trunc $SDF_TRUNC
--depth_trunc $DEPTH_TRUNC \
What do the parameters voxelzize, sdf_trunc, and depth_trunc mean and how to set them？
3、Can we set sh_degree to 3 in citygsv2 \ lfls_sth2_trim. yaml during the Train coarse model step？

Hi, @qqa111, 1. you could try utils/ckpy2ply.py. 2. Please search for TSDF for more details. 3. Yes, of course. Just simply change it in the config file.
