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
