I'm trying to implement the straight skeleton algorithm as described by this paper: http://www.dma.fi.upm.es/personal/mabellanas/tfcs/skeleton/html/documentacion/Straight%20Skeletons%20Implementation.pdf
I am currently stuck trying to understand the author's description of the intersection point B as created from bisector of V, on page 4-5:
I am very confused by this description.
Point B can be characterized as having the same perpendicular distance to the straight line carrying the "opposite" line segment to the vertex V and from both straight lines containing the line segments starting at the vertex V . We have to find such an "opposite" line segment.
- What exactly does opposite mean in this case?
- Does "straight lines containing the line segments starting at the vertex V" refer to its adjacent edges of V?
- Why does Figure 4 show a pre-constructed straight skeleton (the dashed line)? Or.. what is that even? I'm not sure what this diagram is supposed to show.
Please help thank you!
