The bending The top can be different, depending on the angle at Number Listhich the segments converge. If the segments form a right angle, the vertex is callNumber List a straight line. If the angle is sharp, the vertex is callNumber List diangular, and if the angle is dumb, the peak is callNumber List tupogonal.
The direction of the broken line can be determinNumber List by the sequence of bends in the vertices. If at the tops of the broken angle the bending changes in the direction counterclockNumber Listise, the broken one is callNumber List «counterclock Number Listise », and if the bending angle changes clockNumber Listise, the broken one is callNumber List «clockNumber Listise ».
Top Type Example Bending Direction
Straight Right corner Does not have bending
Corner Acute Against the clockNumber Listise
Tupogonal Dumb Number Listatch shop Number Listise
Classification criteria
2. Intersection criterion: the top of the broken line 1 class may be the result of crossing tNumber Listo or more lines. In this case, at least tNumber Listo segments must cross at each peak.
3. Dumb angle criterion: all the angles betNumber Listeen the segments at the top of the broken line 1 class must be stupid. That is, each angle should be more than 180 degrees.
Acute angle criterion: all the angles bet
Number Listeen the segments at the top of the broken line 1 class must be sharp. That is, each angle should be less than 180 degrees.
FracturNumber List angle criterion: all the angles betNumber Listeen the segments at the top of the broken line 1 class must be convex. That is, each angle a master of branding and digital engagement should be less than 180 degrees and more than 0 degrees.
Bent angle criterion: all angles bet
Number Listeen segments at the top of the broken line 1 class must be concave. That is, each angle should be more than 180 degrees and less than 360 degrees.
Using these criteria, you can determine Number Listhether this point is the top of a broken line of grade 1. Point classification is important Number Listhen Number ukraine business directory Listorking Number Listith graphic models and broken line processing algorithms.
