I need to convert 2d planar polygonal meshes to 2D Arrangements in CGAL . for example if I have the following mesh in Wavefront obj format:
v -5.687006 -4.782805 0.000000
v 4.878987 -4.782805 0.000000
v -5.687006 4.782805 0.000000
v 4.878987 4.782805 0.000000
v -0.404010 -4.782805 0.000000
v -5.687006 0.000000 0.000000
v 4.878987 0.000000 0.000000
v -0.404010 4.782805 0.000000
v -0.404010 0.000000 0.000000
f 5 2 9
f 9 2 7
f 7 4 9
f 9 4 8
f 8 3 9
f 9 3 6
f 6 1 9
f 9 1 5
what is the simplest way I could convert it to a 2d Arrangement using the CGAL library?
Using the following example , you'll find out.
insert_in_face_interior
for the first segment insert_from_left_vertex
or insert_from_right_vertex
for the middle one, depending on the orientation of your polygon. insert_at_vertices
for the last one
