Photoshop Script similar to Illustrator Blend Tool for Paths?

hello,

 

for learning purposes create intersection path(s) between subpaths of mainpath using extendscript.

i guess have find difference of each points' coordinates , draw new line using these information. (actually more better if has step options in illustrator blend tool.) since beginner (learning scripting) got confused arrays. being array inside array.

 

i tried 2 ways, none of them completed. since there no point number subpaths array should inside loops suppose

 

please help;

here hopeless tryout...

scripting paths if ps bit of pain. final result want creating these blended paths in ps. might easier use ia , import them ps. playing around paths in ia , ps. wanted scripting of shapes in ps, ability script paths way wanted difficult or didn't work. ended creating paths in ia, converting paths coordinates xml file redrew in ps shape layers apply color based on reference layer in ps.
