Mesh without Displacement Function

[ritsu-a]

Hi authors,

First of all, thanks for your great work!
I am testing the mesh reconstruction quality with/without the displacement function(or base sdf versus combined sdf). I set weaken to 0 in fields_high.py to generate the mesh without the displacement function. However the meshes look almost the same. It seems that no extra details are added, only the surface is slightly moved along its normal.

I noticed that in your supplementary material the difference of extra details seems to be not negligible. Have I made something wrong in mesh reconstruction, or it's exactly the desired results?

Thank you for your attention. For this model, you can set the scale of the position encoding of the base implicit function to be smaller during training.

I was using the checkpoint you provided. Can you help me with more details about the training parameters?
