Detailed Description

An indexed simplex set can be written to a file in ascii or binary format. In addition, it can be exported to VTK XML or VTK legacy format.

For ascii and binary files, the first two numbers identify the space dimension and the simplex dimension. Then the vertex coordinates are enumerated, followed by the tuples of vertex indices that comprise the simplices. These indices are in the range [0..numberOfVertices). The file format is:

  spaceDimension simplexDimension
  numberOfVertices 
  vertex_0_coord_0 vertex_0_coord_1 ... vertex_0_coord_N-1
  vertex_1_coord_0 vertex_1_coord_1 ... vertex_1_coord_N-1
  ...
  numberOfSimplices
  simplex_0_index_0 simplex_0_index_1 ... simplex_0_index_M
  simplex_1_index_0 simplex_1_index_1 ... simplex_1_index_M
  ..
  

For example, the boundary of the unit square in 2-D is:

  2 1
  4
  0.0 0.0
  1.0 0.0
  1.0 1.0
  0.0 1.0
  4
  0 1
  1 2
  2 3
  3 0
  

A triangle mesh of the unit square is:

  2 2
  4
  0.0 0.0
  1.0 0.0
  1.0 1.0
  0.0 1.0
  2
  0 1 2
  0 2 3
