I am trying to implement an algorithm which involves large amount of updates
of a power diagram represented by a regular triangulation. Basically, it
will set the weight and position of each vertex. I am thinking I could have
a vector of vertex_handle to store each vertex information and update vertex
information through this vector. But my concern is after I reset the weight
for a vertex, will the regular triangulation be updated automatically? For
instance, if I set the weight to 0 and in some cases this vertex will be
hidden then, will the hidden flag of the vertex_handle be updated by itself?
Hopefully, I have made my question clear to you guys. And if you have good
suggestions of how to update vertex information of a regular triangulation,
please let me know. Any help would be greatly appreciated.
