NAME

cgalmesh - 3D mesh generation from volumetric image

SYNOPSIS

cgalmesh input.inr output.mesh <angle|30> <surf-size|6> <approx|4> <rad-edge-ratio|3> <tetra-size|8> <randomseed|-1>

DESCRIPTION

The cgalmesh utility is a volume-to-tetrahedral-mesh converter based on the CGAL library (http://cgal.org). This utility is capable of reading a binary, multi-labled or gray-scale based 3D volumetric image and output a tetrahedral mesh conforming to the volume, with each region labeled correspondingly to the volume labels.

Please see https://doc.cgal.org/latest/Mesh_3/ for details regarding the underlying algorithm.

OPTIONS

This program accepts the following input parameters:
input.inr |(required)

The input data file in the INR format

output.mesh |(required)

The output mesh file in the MEDIT format

angle |(optional, default: 30)

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

surf-size |(optional, default: 6)

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

approx |(optional, default: 4)

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

rad-edge-ratio |(optional, default: 3)

Upper-bound of the radius-to-edge ratio of the surface triangles

tetra-size |(optional, default: 8)

Lower-bound of the tetrahedron volume (in voxelห†3) of the 3D mesh

randomseed |(optional, default: -1)

Random number generator seed (large positive integer, -1 to use system clock)
