How to render the clear BEV / novel views automatically from a saved point map?

Hi there.

Fantasic work on flow-based 3D reconstruction! Thhe results really looks fantastic in your paper and supplementary material.

I just have a small question. How can I use a script to automatically render the bev as shown in the supplementary material. I tried to take some examples in scannet++ and arkitscenes but my sight is always fogged by the points at the roof, and I was also troubled by the phenomenon mentioned in #2 .

I just wonder how to obtain the fantastic bev and novel view synthesis results shown in the supplementary material.

Thanks a lot!

Hi @Ma-Weijian, thanks for your interest!

We recommend using viser for rendering. It provides a flexible and interactive interface that makes it much easier to handle occlusions.

Thanks a lot for your advice. However, I am quite new in this area and I just wonder how I can handle occlusions via the interactive interface of viser. Do you mean manually adjusting the camera's near and far?

Indeed, what I would like to do is to render views in an automatic manner that humans do not interfere with the process. Do you have any idea about this? Any idea helps!
