How to enable the optical flow function?

[GANWANSHUI]

Hi, thanks a lot for sharing the excellent work.

I tried to train the 4dgs under the synthesis scene (dnerf), but the output flow value is zero how to enable the optical flow function? Or did I miss anything?

Thanks again!

Hi did you figure it out?

Not yet. An alternative is calculating the offset between two frames, which should derive the optical flow.

Hi did you figure it out? I tried to visualize the offset but it is not right

The flow is compute by flow_2d as input, and it just use volume render to display flow_2d.
