NAME¶

cgalpoly - 3D mesh generation from polyhedral surfaces

SYNOPSIS¶

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

DESCRIPTION¶

The cgalpoly utility is a surface-mesh-to-tetrahedral-mesh converter based on the CGAL library (http://cgal.org). This utility is capable of reading a surface model made of triangular patches and generating a tetrahedral mesh conforming to the surface.

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

OPTIONS¶

This program accepts the following input parameters:

input.off|(required)

The input data file in the OFF 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 voxel^3) of the 3D mesh

randomseed|(optional, default: -1)

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