CGAL users discussion list

[tang <>]

Dear all,

I need to merge neighboring facets which are coplanar. I noticed that the
CGAL has the function 'equal_plane' in 'predicates_on_planes_3.h'. However,
it will return true only when two planes are strictly coplanar. Now my
question is:

how to write a user defined 'equal_plane' function to say two planes are
coplanar if norm2(normal1-normal2)<eps?
where eps is a user defined tolerance.

Is there any function in CGAL to merge coplanar neighboring facets?


Thanks,
Zhanghong Tang
