[postgis-users] Oriented BBox Efficient computing?

[Rémi Cura]

Hey list,
somebody has a good idea about how efficiently computing an approximate
oriented bbox for a polygon ?

The simplest approaches I can think of are
 - iteratively rotate the geom by few degrees, take the envelop. Keep
ration where envelope is min
 - using Principal Components Analysis  : extract points regularly spaced
on border of object,  compute PCA .

Thanks,
Cheers,
Rémi-C
