Generates successive polyline approximations of lwpolyline/polyline3d objects to smooth out the original shape but keep the overall polyline trend.

Morphs one polyline into another by generating intermediate polylines at arbitrary stages of the process.

Attempts to improve a field survey in certain cases by creating a smoothed out version of an original 3d polyline
