Additional morphing points (type "extra") explained
Hello, i struggle to understand how the extra morphing points are meant to be used. How do they work technically? How do i correctly set them? Are they linked to the nearest station and could i use more than two extra points? Are they linked to LRUD data? I already investigated the "morohing" example from the documentation (both in code and in thbook), so i think it would be good to stick to this example. Thank you very much!

Hi Benedikt, the purpose of these extra points is to correct differences between LRUD data (if available) and distances to walls in sketches. Check page 89 of TherionBook. m.
Thank you for the fadt reply. If i understand and interpret correctly, the behavior unfolds in the following way: - when i detect inproper morphing of walls compared to lrud data - i place "extra" points on my traced wall signature. - the extra point position is approximately where the lrud point is assumed to be on the wall. - when rendering, therion morphes the wall to match the extra point position to the corresponding lrud position for that point (which is the nearest station). That would imply: a) there is no use for extra points without lrud data. b) extra points reference l+r positions of lrud data of the nearest station, therefore it is not possible to set more than two extra points per station. Is the above true? Am 2016-11-18 11:20, schrieb Martin Sluka:

page 35: • dist <distance> ◃ valid for extra points, specifies the distance to the nearest station (or station specified using -from option. If not specified, appropriate value from LRUD data is used. • from <station> ◃ valid for extra points, specifies reference station. It means you may specify it "everywhere", not only on walls point extra -dist 12 m -from A1234 m.

According to the therion book (p. 25), extra points can also be used without LRUD by specifying the distance to either the closest station of a specific station, e.g.: point 0.0 0.0 extra -dist 3 -from 2@mysurvey I have not tried yet, though. Xavier Le 18/11/2016 11:52, Benedikt Hallinger a écrit :

Thank you very much! The extra point then just basicly just indicates "this *known* point is xx meters away from point y"; as is the (implicit) same for the LRUD data. In other words, the LRUD data generates implicitely such points if present. Just to clarify (and for the archive): To correct an arbitary wall between two long survey legs, i would place two extra points at the middle of the leg at the position where i have drawn my wall signature. Then i would enter the "-from" info and the respective -dist to that point. I just tested this and it works like desired, however it involves a little fiddling. Thanks again for clarifying this!

The purpose of this feature was to correct field sketches to LRUD for example. m. On Nov 18, 2016, at 03:47 PM, Benedikt Hallinger <beni@hallinger.org> wrote: Thank you very much!
