Query regarding Sigma about pifu

[shunsukesaito]

In the paper, the sigma was in cm unit. If you rescale the objects, you need to adjust the sigma accordingly. Dumping out the sampled points after normalization as PLY or OBJ files and previewing it via meshlab is highly recommended.

Hi,

The ply is as below.

You can load the normalized mesh file in the same viewer to see if the points are nicely distributed around the surface. If not, likely, you set sigma too big.

Thanks for the reply. It worked by tweaking TrainDataset.py. Also, subtracting vertices with trimesh's mesh.center_mass also helps.

Hi @jsaisagar ,
How did you tweak the TrainDataset.py?
I'm also getting marching cube error and the error value is 0.0000 if the sigma is 5. But when i used sigma=0.5, I'm getting error value 0.01. But I'm still getting marching cube error.
As @shunsukesaito said,how to dump sampled points after normalization so that i can open in meshlab and get some insight?
Please feel free to discuss.
Thanks.
