Computes the geodesic distance to all vertices in a triangulated mesh from a given starting vertex.

First install using npm:

```
npm install mesh-geodesic
```

Then call it as follows:

```
var bunny = require("bunny")
console.log(require("mesh-geodesic")(bunny.cells, bunny.positions, 0))
```

`require("mesh-geodesic")(cells, positions, initialVertex[, maxDistance, tolerance, dual])`

Computes the geodesic distance to an initial vertex. Takes the following arguments:

`cells`

: The cells of the mesh`positions`

: The positions of the mesh`initialVertex`

: Index of the starting vertex`maxDistances`

: (Optional) The total distance to travel to find all points. If not specified, is set to Infinity`tolerance`

: (Optional) Accuracy of distance field. (Default 1e-4)`dual`

: (Optional) Topological dual of mesh. Can be computed using`require("simplicial-complex").dual`

Returns an object containing the distances to all vertices from `initialVertex`

This package was written back when I first started learning JavaScript, and probably has several bugs. It is also very slow and uses the outdated vows test harness (whereas if I were to do it again today, I would use tap). Nonetheless, it still should compute geodesics for you to some (low) level of accuracy.
