volSurfaceRegularization

Regularize a cubical complex into a smooth quadrangulated complex.

This is done by minimizing a quadratic energy function as decribed in ??. The variational formulation regularizes the position while aligning the regularized quads with an input normal vector field. In this tool, the input normal vector field can be either specified in the CSV input file, or computed using Integral Invariant (and -r option).

Usage: volSurfaceRegularization -input <volFileName> -o <regularizedcomplex.obj>

Allowed options are :

Positionals:
  1 TEXT REQUIRED                       input vol filename for image shape (object voxels have values > 0) or input cvs filename for surfels and normals
  1 TEXT REQUIRED                       output regularized obj

Options:
  -h,--help                             Print this help message and exit
  -i,--image-filename TEXT REQUIRED     input vol filename for image shape (object voxels have values > 0) or input cvs filename for surfels and normals
  -o,--regularized-obj-filename TEXT REQUIRED
                                        output regularized obj
  -n,--cubical-obj-filename TEXT        output cubical obj
  -k,--shape-noise FLOAT=0              noise shape parameter
[Option Group: Normal field estimator options]
  Options:
    -r,--normal-radius FLOAT=4            radius of normal estimator
[Option Group: Surface approximation options]
  Options:
    -p,--regularization-position FLOAT=0.001
                                          vertex position regularization coeff
    -c,--regularization-center FLOAT=0.01 face center regularization coeff
    -a,--align FLOAT=1                    normal alignment coeff
    -f,--fairness FLOAT=0                 face fairness coeff
    -b,--barycenter FLOAT=0.1             barycenter fairness coeff

Example:

$ volSurfaceRegularization -i bunny.vol -o bunny_smooth.obj

You should obtain such a result:

Input cubical complex.

Smooth quadrangulated complex.
