Program Single_estimation
|
|
---------------------
|
|
takes as input a <inputPoints.txt> which is a xyz text file
|
|
it compute the fitting for this single entry and
|
|
it outputs results in the <output.txt> file and on the standard std::cout
|
|
|
|
Usage is : Single_estimation <inputPoints.txt> <d_fitting>, <d_monge>"
|
|
|
|
in_points are sampled on 0.1(x²+2y²)

Program Mesh_estimation
|
|
-----------------
|
|
takes an filename.off file as input,
|
|
it computes a fitting for each vertex
|
|
|
|
it outputs the results in :
|
|
1. filename.off.4ogl.txt which records raw data (better for a vizualization
|
|
post-processing)
|
|
2. if option -vtrue, filename.off.verb.txt contains human readable results
|
|
|
|
Allowed options:
|
|
-h [ --help ] produce help message.
|
|
-f [ --input-file ] arg (=data/ellipe0.003.off) name of the input off file
|
|
-d [ --degree-jet ] arg (=2) degree of the jet
|
|
-m [ --degree-monge ] arg (=2) degree of the Monge rep
|
|
-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
|
|
-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 vertex is skipped.
