<div dir="ltr">Dear Jon, Arnaud,<div><br></div><div>Thanks a lot for your answers, and sorry that I missed your answers for a long while.</div><div><br></div><div>I didn't try to visualize it (never managed to write vectors on vtk polydata, probably is very easy but I must admit I've been rather sloppy regarding that).</div>
<div><br></div><div>What Arnaud commented makes a lot of sense. On my case, I empirically check the direction and they are inwards. But probably, it'd be much faster and reliable if I checked the order of triangles as Arnaud suggested.</div>
