[Meshlab-devel] no edge information in the data structure?

[Shi Y. <bil...@gm...>]

hello guys,

i'm working on a project that adaptively subdivide an object based on
the curvature of each edge.

currently, i'm using CGAL. but it is very slow.

i found that the remeshing rountines of MeshLab run very fast. so i
want to switch to VCG.

however, it seems that the data structure of the VCG Library is not a
half-edge structure that has no edge information at all, because i
found this line
in the subdivision sample:

class MyEdge;    // dummy prototype never used

and i couldn't find any instruction on this page about accessing edge
information:
http://meshlab.sourceforge.net/wiki/index.php/Accessing_the_mesh

my question is how to travel through all the edges? is that true that
VCG data structure doesn't have edge info at all?

thank you.
