remove-degenerate-cells
=======================
### Removes degenerate cells in a simplicial complex
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]
]
}
*/
```
