Program blind_1pt
|
|
---------------------
|
|
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 : main <inputPoints.txt> <output.txt> <d_fitting>, <d_monge>"
|
|
|
|
in_points are sampled on 0.1(x²+2y²)
|
|
|
|
./blind_1pt data/in_points_file.txt output.txt 2 2
|
|
./blind_1pt data/in_points_d4.txt output.txt 4 4

Program blind
|
|
-----------------
|
|
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 can be visualized with
|
|
the demo program introspect-qt
|
|
2. if option -v, filename.off.verb.txt contains human readable results
|
|
|
|
Usage is : blind with options
|
|
"f:fName <string>", // filename.off
|
|
"d:deg <int>", // degree of the jet
|
|
"m:mdegree <int>", // degree of the Monge rep
|
|
"a:nrings <int>", // # rings
|
|
0 means collect enough rings to make appro possible
|
|
k>=1 fixes the nb of rings to be collected
|
|
"p:npoints <int>", //# points
|
|
0 means this option is not considered, this is the default
|
|
n>=1 fixes the nb of points to be used
|
|
"v|", // verbose?
|
|
|
|
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.

./blind -f data/poly2x\^2+y\^2-0.062500-off -d2 -m2 -a2
