Re: [postgis-users] Tutorial: Bezier Curves - A More Flexible Alternative to Great Circles

2015-03-05 Thread Rémi Cura
Hey,
nice work !
I'm adding this to my personnal toolbox .

I'm a little curious because I know you are a R user, why didn't you use R
package to compute bezize, there are several?
Is this a portability issue?

For the interpolation, this can be substantially more difficult if you
allow outliers, etc.
(I would use R or python, because some modules already do this)

Cheers,
Rémi-C

 Nice work Mark, well done, would you have a version to perform Bezier
 spline interpolation?

 Many people like looking at maps that show flight paths.  I’ve just
 posted a tutorial outlining an approach which gives the user the ability to
 set the degree of bend or flex in the curve, the number of vertices (useful
 for time series animations) and a break value which splits the linestring
 in two at a specified meridian.
