remove-degenerate-cells
=======================

$3

Removes degenerate cells in a simplicial complex and reindexes the cells array.

Install
-------

``bash
$ npm install remove-degenerate-cells
`

Usage
-----

Using cell indices alone

`javascript
var removeDegenerateCells = require('remove-degenerate-cells');

var mesh = {
cells: [
[0, 1, 2],
[0, 1, 1]
],
positions: [
[0, 0, 0],
[1, 0, 0],
[0, 1, 0],
]
}

mesh.cells = removeDegenerateCells(mesh.cells);

console.log(mesh);
/*
{
cells: [
[0, 1, 2]
],
positions: [
[0, 0, 0],
[1, 0, 0],
[0, 1, 0]
]
}
*/
`

Using vertex positions

`javascript
var removeDegenerateCells = require('remove-degenerate-cells');

var mesh = {
cells: [
[0, 1, 2],
[0, 1, 3]
],
positions: [
[0, 0, 0],
[1, 0, 0],
[0, 1, 0],
[0, 0, 0]
]
}

mesh.cells = removeDegenerateCells(mesh.cells, mesh.positions);

console.log(mesh);
/*
{
cells: [
[0, 1, 2]
],
positions: [
[0, 0, 0],
[1, 0, 0],
[0, 1, 0],
[0, 0, 0]
]
}
