polygon.soup.to.indexed.mesh: Turn polygon soup into indexed mesh.

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

Turn polygon soup into indexed mesh.

Description

Some mesh file formats like STL do not store the faces as indices into a vertex list ('indexed mesh'), but repeat all vertex coordinates for each face ('polygon soup'). This function creates an indexed mesh from a polysoup.

Usage

polygon.soup.to.indexed.mesh(faces_vertex_coords, digits = 6)

Arguments

faces_vertex_coords	numerical matrix with *n* rows and 3 columns, the vertex coordinates of the faces. Each row contains the x,y,z coordinates of a single vertex, and three consecutive vertex rows form a triangular face.
digits	the precision (number of digits after decimal separator) to use when to determine whether two x,y,z coords define the same vertex.

Value

an indexed mesh, as an 'fs.surface' instance (see read.fs.surface).
