After having calculated the raw SDF value for each facet, several post-processing steps are applied. After having calculated the raw SDF value for each facet, several post-processing steps are applied.
First, facets with no SDF values are assigned the average SDF value of their one-ring edge-adjacent neighbors. If there is still a facet having no SDF value, First, facets with no SDF values are assigned the average SDF value of their edge-adjacent neighbors. If there is still a facet having no SDF value,

The main reason for not assigning 0 to facets with no SDF values is that it can obstruct log-normalization process which takes place at the beginning of `segment_from_sdf_values()`.
