Ridge Detection Plugin question

Tags: #<Tag:0x00007fd5487aae48>


Does anyone know what the “Angle of normal” result variable is (geometricaly/trig) in the Ridge Detection plugin? I’m trying to draw an arrow normal to the ridges by using the average “Angle of normal”, but can’t figure out how to use it…it seems to vary unpredictably from quadrant to quadrant when I take it’s tangent.



Maybe the javadoc of the Line class gives some insight:

Otherwise, @twagner might be able to help further.


Thanks Jan…This explains the problem.
