Hi !

I use boost geometry to draw polygons with feathering. I need to compute
distance from many points to the different polygons rings (outer and
inners).
To compute the distance from a point to a ring, I iterate over the ring
segments and use boost::geometry::comparable_distance from point to segment.

To optimize it I was looking at the R-Tree. Is that an option ? Would it
help getting the minimum distance from a point to a ring ? With an R-Tree
containing all ring segments ?
Any link is much appreciated !

Thanks !
