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

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?

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.
