Implementation on NeRF framework

[hskAlena]

Hello! Thanks for your amazing work!

I'm trying to implement your fisherRF in the NeRF framework.
The problem is that in NeRF, the model parameters do not directly correspond to spatial locations.
So, to visualize the pixel-wise uncertainty, ChatGPT advised that I render and get gradients of every pixel (ray) one by one.

However, how can I render the computed uncertainty? It is hard to volume-render the gradients of model parameters.
Can I just sum up the pixel-wise uncertainties?

Hello, thank you for your interest in our work! Apology for losing track of this issue. We did our experiments on plenoxels which has explicit parameters on 3D locations. Feel free to let me know if you have any further questions :-)

so interesting! how is the project going?
