# Convertor from Vertices-Faces Representation to 3-Block Representation

### Description

Converts a polyhedron from the vertices-faces representation to the three-block representation.

### Usage

1 | ```
vf2blocks(Vertices,Faces)
``` |

### Arguments

`Vertices` |
N by 3 matrix containing the XYZ coordinates of N vertices |

`Faces` |
M by 3 matrix containing indices of vertices defining M faces |

### Details

The values in the `Face`

matrix must be integers with values running from 1 to N,
where N is the number of vertices. A value of '1' in this matrix, for example,
represents the 1st vertex, i.e., the vertex defined by the first row in the
matrix `Vertices`

.

This function is the inverse of the `blocks2vf`

function.

### Value

Returns a list of three matrices. The first is an M by 3 matrix containing the XYZ coordinates of vertex 1 of the M faces of the polyhedron. The second and third are similarly M by 3 matrices, but contain the XYZ coordinates of vertices 2 and 3 of the faces. See the example below.
