Program Compute_Ridges_Umbilics
-----------------
takes a polyhedron (filename.off file) as input,
it computes a jet fitting to set the monge data at each vertex
computes the ridge lines and the umbilics
it outputs the results in :
1. filename.offRIDGES-d?-m?-t?-a?-p?.4ogl.txt which stores raw data to be used for a nonprovided further processing (visualization for instance, the interested user may want to build on top of the polyhedron package demo)
2. if option -vtrue, filename.offRIDGES-d?-m?-t?-a?-p?.verb.txt contains human readable results
Allowed options:
-h [ --help ] produce help message.
-f [ --input-file ] arg (=data/ellipsoid_u_0.02.off) name of the input off
file
-d [ --degree-jet ] arg (=3) degree of the jet, 3 <=
degre-jet <= 4
-m [ --degree-monge ] arg (=3) degree of the Monge rep,
3<= degree-monge <=
degree-jet
-a [ --nb-rings ] arg (=0) number of rings to
collect neighbors. 0
means collect enough
rings to make appro
possible a>=1 fixes the
nb of rings to be
collected
-p [ --nb-points ] arg (=0) number of neighbors to
use. 0 means this
option is not
considered, this is the
default p>=1 fixes the
nb of points to be used
-t [ --tag_order ] arg (=3) Order of differential
quantities used, must be
3 or 4
-u [ --umbilic-patch-size ] arg (=2) size of umbilic patches
(as multiple of 1ring
size)
-v [ --verbose ] arg (=0) verbose output on text
file
Note : if the nb of collected points is less than the required min number of
points to make the approxiamtion possible (which is constrained by the deg)
then the program exits.
EXAMPLES
---------------------------------------------------------
