How to link the grain boundary properly?

[MaynotbeGarychan]

Hi,
Currently, I am making an interface to convert the grains object of MTEX to the geometry of grains and grain boundary in gmsh.
I know there are some outstanding tools, like MTEX2Gmsh, to achieve similar purpose.
But, I want to implement others features.
Now, I try to use the information of the grains.boundary to make the geometry. I noticed there are some useful midPoint, and direction of the line segments of the grains boundary. However, I don't know the sequence of this points. Therefore, when I convert them into Gmsh, the line segment is incorrect, see the attached.
Therefore, would you please tell me that when you are using "plot(grains.boundary)", how can you link them in a correct sequence?

Thanks!!

Hi,

may have a look into grainBoundary/plot, there's a function called plotOrdered2 as well as plotSimple, the former using `EulerCycles2'. I hope this helps.
