You still looking for a help .

What's the issue buddy .

yajis_narif · 发表于 2022-7-6 10:09:05

i have a drawing with 4 lines of points (each line of points with the same Y) . i have the coordinate of the points of each line in a list and all the lists in a list .
so now i want to calculate the disatnce between points of each list knowing that the number of points in lines may change and may not be equal as follows :
.  .  .  .  .
.  .  .  .  .
.  .    .  .
.  .  .

thanks tharwat

You want to calculate the distance from the list or from the distance between points ?

yajis_narif · 发表于 2022-7-6 10:16:07

yes i want to calculate the distance between points in every line

If your point list is in the format:

copy

( (  ... ) (  ... ) ... (  ... ))

then perhaps:

copy

(defun test ( mainlist ) (mapcar   (function     (lambda ( sublist )       (mapcar 'distance sublist (cdr sublist))     )   )   mainlist ))

yes exactly my list is in that format and i want to calculate the distance between ( and ) ,( and )...... and )

Lee Mac · 发表于 2022-7-6 10:25:40
