output data seems to be inverted? #2

if I take the output of the surface net algorithm here and put it into .stl and render it, it shows up as inside out:

however, if I load the same exact data into your isosurface toolbox (which has material.doubleSided = true) it looks okay

do you know what's going on here and how I might get normal looking .stls?

That is a convention that your renderer has to decide on. If you want the facets in a different order, just swap two vertices in each of the faces.

Or alternatively you could change the sign of the implicit function you are using.
