write.fs.surface.mz3: Write mesh to file in mz3 binary format.

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

Write mesh to file in mz3 binary format.

Description

Write mesh to file in mz3 binary format.

Usage

write.fs.surface.mz3(filepath, vertex_coords, faces, gzipped = TRUE)

Arguments

filepath	string. Full path to the output surface file, should end with '.mz3', but that is not enforced.
vertex_coords	n x 3 matrix of doubles. Each row defined the x,y,z coords for a vertex.
faces	n x 3 matrix of integers. Each row defined the 3 vertex indices that make up the face. WARNING: Vertex indices should be given in R-style, i.e., the index of the first vertex is 1. However, they will be written in FreeSurfer style, i.e., all indices will have 1 substracted, so that the index of the first vertex will be zero.
gzipped	logical, whether to write a gzip compressed file

Value

string the format that was written. One of "tris" or "quads". Currently only triangular meshes are supported, so always 'tris'.

Note

This format is used by the surf-ice renderer. The format spec is at https://github.com/neurolabusc/surf-ice/tree/master/mz3.

Examples

## Not run: 
    # Read a surface from a file:
    surface_file = system.file("extdata", "lh.tinysurface",
     package = "freesurferformats", mustWork = TRUE);
    mesh = read.fs.surface(surface_file);

    # Now save it:
    write.fs.surface.mz3(tempfile(fileext=".mz3"), mesh$vertices, mesh$faces);

## End(Not run)
