hi all
i try make contours from DEM ASTER and i was successfull but contorus is ugly i try use v.generalze but this function cant change firt and las point , but some contrours is like loop (first and last point is the same) so after smoothing with sliging_averaging algo part around start point look_ahead wide was unchanged iwas so ugly , so i write patch which implementing loop line support , check if line is loop (start and endpoint is same ) and smooting correctly, is it usabel for others ?
attachment:
black is war contours, blue is orig algo and red is with my patch

Yes, I think this is usuable for others. Do you mind sending the patch?

is it ok ?
it add new parameter loop_support which would be 1 or 0 for loop line support in
sliging_averaging algo

I have added your loop support in r56252, with slight modifications:
loop support is activated with the -l flag.
Thanks for the contribution!

Now the smoothing algorithms boyle, chaiken, distance_weighting,
hermite, snakes also have loop support.

Excellent - I have added this to

Loop support is now the default for all smoothing methods.

Updated accordingly.
