eval-grid

=========

Initializes an n-dimensional array with a specified function.  Useful for plotting and volume visualization.

Installation

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

Via npm:

    npm install eval-grid

Example

=======

Running:

    console.log(require("eval-grid")([3, 3, 3], function(x) {

      return x[0] + x[1] + x[2];

    });

    

Prints:

    [ [ [ 0, 1, 2 ], [ 1, 2, 3 ], [ 2, 3, 4 ] ],

      [ [ 1, 2, 3 ], [ 2, 3, 4 ], [ 3, 4, 5 ] ],

      [ [ 2, 3, 4 ], [ 3, 4, 5 ], [ 4, 5, 6 ] ] ]

      

`require("eval-grid")(dims, func)`

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

This initializes an n-dimensional image, with dimensions `dims` using `func`.

* `dims` are the dimensions of the image to initialize.

* `func` is the function to initialize the grid with.  It takes an array of integer coordinates with length = `dims.length` as input and returns the value to initialize the grid with.

Returns the initialized grid.
