NAME

       cgalsurf - 3D surface mesh extraction from volumetric image

SYNOPSIS

       cgalsurf  input.inr  threshold  x0 y0 z0 r2 angle surf-size approx maxnode output.off <randomseed> <init-
       size>

DESCRIPTION

       The cgalsurf utility extracts a surface mesh at a specified threshold (level-set) from a volumetric image
       - either in binary or gray-scale values, using  the  CGAL  library  (http://cgal.org).  This  utility  is
       adapted based on the 3D surface generation demo in the CGAL package.

       Please see https://doc.cgal.org/latest/Surface_mesher/ for details regarding the underlying algorithm.

OPTIONS

       This program accepts the following input parameters (all but the last two parameters are required):

       input.inr
              The input volumetric image in the INR format

       threshold
              A number representing the threshold at which the surface is extracted.

       x0     The bounding sphere center x-coordinate

       y0     The bounding sphere center y-coordinate

       z0     The bounding sphere center y-coordinate

       r2     The bounding sphere's radius squared

       angle  Lower-bound of the angles (in degree) in surface triangles

       surf-size
              Lower-bound of the edge-length (in voxel unit) in surface triangles

       approx Upper-bound  of  the  deviation distance (in voxel unit) of the surface triangles to the voxelated
              boundaries

       maxnode
              Upper-bound of the node numbers in the output mesh

       output.off
              Output surface mesh in the OFF format

       randomseed|(optional, default: -1)
              Random number generator seed (large positive integer, -1 to use system clock)

       init-size|(optional)
              The number of nodes  in  the  initial  surface  (sampled  on  the  bounding  sphere)  cgalmesh(7),
              cgalsimp2(7), cgalpoly(7), cork(7), meshfix(7), jmeshlib(7)
