Split polygon into smaller polygons based on number of vertices

Hello,

 

Could someone provide some information on how i would go about breaking apart a polygon based on the number of vertices the polygon has. It has to be similar to the ST_Subdivide postgis function. This function breaks the polygon into smaller polygons at right angles.

@od10​  Try the Chopper transformer. There is also a GridChopper on FME HUB

@Mark Stoakes​ It looks like Chopper does the job in terms of splitting the polygons by number of vertices however it doesn't create vertices inside the chopped polygon like the ST_Subdivide does. Is there any way of getting the same output easily in FME?ST_Subdivide

@bocaj​ I think the GridChopper is the closest we have to that. It is a custom transformer so it might be possible to modify that to give a better results
