    initial v1

     17{{{
    171820:24:28 < hobu> Someone needs to do some splining
    181920:24:29 < crschmidt> Should I bother to file it as a bug?
     
    232420:26:19 < hobu> Another thing about the splining is we could maybe take advantage of it for feature rendering as well
    242520:26:38 < hobu> something those paleogeographers do from time to time ;)
    25 
     26<crschmidt>     what is that?
     27<crschmidt>     straightening out of too-curvy borders?
     28<hobu>  smoothen disjointed ones. They add map noise for very little information
     29* crschmidt     nods
     30<crschmidt>     something like what a simplification algorithm would do
     31<crschmidt>     only automatic/built into the rendering?
     32<hobu>  right, except not one that has to preserve topological relationships
     33<hobu>  http://en.wikipedia.org/wiki/B-spline
     34<hobu>  Would be a simple approach
     35<hobu>  Maybe you'd tell the mapserver renderer, 'hey, use 6-8 consequtive vertices to calculate your splines, if the incident angle is less than x degrees"
     36<hobu>  or something like that ;)
     37<hobu>  It'd be spendy, for sure
     38<hobu>  and not very useful for Manhattan grid systems :)
