How to create the df data of other resolution? And a question about the content of df data.

[TrepangCat]

I hope to create the df data of other resolutions, e.g. 64. But I do not find any code about this. Could you share the corresponding codes?

And here is a detail about data, I can't understand. It seems that there is no minus value in df data. So what do you save in voxel grids? I used to think they are signed distance function values.

We use distance function instead of signed distance function, since most of the meshes are not watertight.
I'm not sure if I can trace down the exact code for df calculation, but this process is quite simple: for each grid location, we find the nearest triangles on the mesh and use point to triangle distance as the value of that grid.
