I am trying to implement my problems in different ways. So, may be though this question has some relation to some other questions, please answer me.
We know; Intersection of two planes will be given a 3D line. (In case of segments of planes, then we will have a 3D line segment for the sharing edge portion of both planes, and my question is referred with this).
If I need to assign weights for each line, then this can be achieved with respect to the degree of angle between two planes. So, I can say when two planes make 90 degrees, then the produced line is more precise than when the line subtends 150 or close to 180 degrees. So the 90 degree case give one weight and 150 case give another weight. (I think, this weight tells, how accurately model these lines. so, I can consider this also as quality of the lines. maybe, I am wrong.)
So, I want to know some degree of measure to assign weights in order to discriminate the lines in terms of angle between two planes. So, could you please elaborate how I can categorize different weight classes in terms of that angle as I am really poor in geometry? Or maybe there are some other measures like; length of line segment or size or plane segments. Thank you in advance.
