Can 3DGS render depth maps?

This is 'almost' point cloud so you can render depth map. (eg https://www.techrxiv.org/users/687263/articles/680135-three-to-two-a-novel-approach-for-converting-3d-point-clouds-into-2d-depth-maps )

Yes it can do depth calculations in this repo's own render function

Thanks.

I have another question, are the RGB and depth maps rendered at the same view aligned?
Will the 3D points generated by the RGB and depth maps rendered at any view find corresponding points in the 3DGS model?

Yes the renderer takes in a view direction, outputs the produced image as well as depth from that view.
It can be any view, in case of trainer its a training view, but it can be anything.
look at here: https://github.com/graphdeco-inria/gaussian-splatting/blob/c643c864416c5258c76cd9f0eed55203834cbf83/train.py
line 94 and 106.

Thank you for your answer. Since the depth map and RGB map can be rendered, why can't I get a point cloud with uniform density?
