eval-grid

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

Installation

Via npm:

npm install eval-grid

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 ] ] ]

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.
