Signed distance field computations for meshes

Usage & Install

===============

Via npm:

    npm install signed-distance

Here is how you can use it:

```js

    var mesh = require("bunny");

    var dist = require("signed-distance")(

                  require("spatial-grid")(mesh.cells, mesh.positions, 0.1), 

                  require("normals").faceNormals(mesh.cells, mesh.positions),

                  [1.0, 0.0, 0.0]);

```                  

`require("signed-distance")(grid, faceNormals, point)`

------------------------------------------------------

Computes the signed distance to the mesh from `point`

* `grid`: A spatial grid

* `faceNormals`: The normals of the mesh

* `point`: The point to query

Returns: The signed distance to the boundary of the mesh, or else NaN
