Hello

I noticed that when we open a NIFTI file in Slicer, it automatically applies a transformation to the mesh and make it smooth. I would like to know if we can access this feature through Python code? And what is the algorithm used behind?

Thank you in advance for your response  
Bests

Maybe you are talking about loading a binary mask that was saved as NIFTI, and loading it as a segmentation?
