Computes generic scalar surfel data comparisons (squared error) (given from an input data file and from a reference one).

Usage: 3dCompSurfelData [input] [reference]

Allowed options are:

Positionals:
  1 TEXT:FILE REQUIRED                  input file: sdpa (sequence of discrete points with attribute)
  s TEXT:FILE                           input file: sdpa (sequence of discrete points with attribute)
 
Optionals:
  -h,--help                             Print this help message and exit
  -i,--input TEXT:FILE REQUIRED         input file: sdpa (sequence of discrete points with attribute)
  -r,--reference TEXT:FILE REQUIRED     input file: sdpa (sequence of discrete points with attribute)
  -l,--compAccordingLabels              apply the comparisos only on points with same labels (by default fifth colomn)
  -a,--drawSurfelAssociations           Draw the surfel association.
  -o,--fileMeasureOutput TEXT           specify the output file to store (append) the error stats else the result is given to std output.
  -n,--noWindows                        Don't display Viewer windows.
  -d,--doSnapShotAndExit TEXT           save display snapshot into file. Notes that  the camera setting is set by default according the last saved configuration (use SHIFT+Key_M to save current camera setting in the Viewer3D).
  --fixMaxColorValue FLOAT              fix the maximal color value for the scale error display (else the scale is set from the maximal value)
  --labelIndex UINT                     set the index of the label (by default set to 4)
  --SDPindex UINT x 4                   specify the sdp index (by default 0,1,2,3).

Example:

To use this tools we need first to have two differents surfel set with an attribute to be compared. We can use for instance the curvature from the sample file of DGtal/examples/samples/cat10.vol:

# generating another input vol file using tutorial example (eroded.vol):
$ $DGtal/build/examples/tutorial-examples/FMMErosion
# Estimate curvature using other DGtalTools program:
$ 3dCurvatureViewer -i $DGtal/examples/samples/cat10.vol -r 3 --exportOnly -d curvatureCat10R3.dat
$ 3dCurvatureViewer -i eroded.vol -r 3 --exportOnly -d curvatureCat10ErodedR3.dat

Now we compare the different curvature values from the two shapes:

./visualisation/3dCompSurfelData curvatureCat10ErodedR3.dat curvatureCat10R3.dat --fixMaxColorValue 1.0 -o statMeasures.dat

You should obtain such a visualisation:

resulting visualisation of curvature comparison.
