write.stl.ascii: Write the sections of a triangular mesh in ASCII STL format.

In freesurferformats: Read and Write 'FreeSurfer' Neuroimaging File Formats

Write the sections of a triangular mesh in ASCII STL format.

Description

Writes the 'solid' block of the ASCII variant of the STL format, with 7 lines per face ('facet normal', 'outer loop', 3 'vertex' lines, 'endloop', 'endfacet'). This is the layout that read.fs.surface.stl.ascii and other STL readers expect.

Usage

write.stl.ascii(con, vertex_coords, faces, face_normals, solid_name = "mesh")

Arguments

con	a connection opened in binary write mode, the file is written as text through it.
vertex_coords	n x 3 matrix of doubles, the vertex coordinates.
faces	n x 3 matrix of integers, the vertex indices of the triangles.
face_normals	n x 3 matrix of doubles, the normals of the faces, see mesh.face.normals.
solid_name	character string, the name of the mesh.

Value

NULL, invisibly. The data are written to con.
