Data preprocessing

[qingshu-hui]

Hi,
thank you for the excellent work, but I ran into a problem during the reproduction process:

How is the.obj/.ply file obtained before sampling SDF points or surface points in the data preprocessing stage?
I tried to build the corresponding mesh from the mask in the original data set, but the generated results are quite different from the pre-processing results you gave. The pancreas_0001 figure below is an example, so could you please realse the preprocessing code for generating organ shapes given the center-cropped mask volumes? I want to know if I understood something wrong.

My results

Your results

Thanks a lot in advance.
