Method Details

writePolyedronToOFF

public static void writePolyedronToOFF(Polyhedron_3 mesh,
 String filename)

Output a 3D (surface) triangulation to OFF file

Warning: only for triangle meshes (faces must be triangular)

Parameters:

mesh - a triangulation (Half-edge representation)

writeReversedPolyedronToOFF

public static void writeReversedPolyedronToOFF(Polyhedron_3 mesh,
 String filename)

Reverse the orientation of the input surface and output to OFF file.
The orientation of the faces is reversed.

Warnings:
-) only for triangle meshes (faces must be triangular)
-) the orientation of the input mesh remains unchanged

Parameters:

mesh - input triangulation (Half-edge representation)

writePolyedronToOFF

public static void writePolyedronToOFF(Polyhedron_3 mesh,
 double[][] edgeColors,
 String filename)

Output a 3D (surface) triangulation to OFF file

Parameters:

mesh - a triangulation (Half-edge representation)

edgeColors - an array containing the colors of edges (one for each half-edge) warning: only for triangle meshes (faces must be triangular)

writePolyedronToMETIS

public static void writePolyedronToMETIS(Polyhedron_3 mesh,
 String filename)

Output a 3D (surface) mesh to METIS file

Parameters:

mesh - a triangulation (Half-edge representation)

writePolyedronToEDGES

public static void writePolyedronToEDGES(Polyhedron_3 mesh,
 String filename,
 String separatingText)

Output a 3D (surface) mesh as a list of EDGES (with vertices separated by commas)

Indices of vertices start from 0

Parameters:

mesh - a triangulation (Half-edge representation)
