hLutChamfer3D checks if a G-symmetrical chamfer mask induces a norm or not and, for norms, computes the medial axis test neighborhood and lut values.

Licence: This program is free software under the terms of the GNU Lesser General Public License (LGPL) version 3.

Usage:

hLutChamfer3D	[-r|--maxradius max_radius]
		[-w|--weights a b c d...]
		[-m|--mask weighting_count x y w... x y w]
		[-o|output outputfile]

example: hLutChamfer2D -r 2000 -m 4 1 0 14 3 1 44 2 1 31 1 1 20

Return codes:

• 0 success
• 255 not a norm

Additional output streams:

• 3 elapsed time
• 4 list visited points
• 5 H-polytope matrix of chamfer balls (facet normal vectors)
• 6 H-parameters of chamfer balls

Examples:

• compute the test neighborhood and lut values for the mask <4,6,7,9,10> for a maximal radius equal to 2000:

   hLutChamfer3D -r 2000 -w 4 6 7 9 10 -o -
  

• check if the mask <3,4,7> induces a norm (in this case, return code 255: not a norm)

   hLutChamfer3D -w 3 4 7
  

• print the facet normal vectors of the equivalent rational ball for the mask <7,8,11,14> on the standard output:

   hLutChamfer3D -w 7 8 11 14 5>&1
