Code to generate same tiles as marzipano tool

[ssandison]

I have tried the example code to generate the same tiles that marzipano tool does but I can't seem to get the same folder structure.

My source image is 10000x5000 pixels and when tiles are generated via marzipano I get the following structure:

Using the library:

The tile size seems to be different too.

This is what is generated from marzipano scene data:

var APP_DATA = {
"scenes": [
{
"id": "0-reception",
"name": "Reception",
"levels": [
{
"tileSize": 256,
"size": 256,
"fallbackOnly": true
},
{
"tileSize": 512,
"size": 512
},
{
"tileSize": 512,
"size": 1024
},
{
"tileSize": 512,
"size": 2048
}
],
"faceSize": 4096,

The code that loads the tiles is:

  var source = Marzipano.ImageUrlSource.fromString(
    data.tilesURL + "/{z}/{f}/{y}/{x}.jpg",
    { cubeMapPreviewUrl: data.tilesURL + "/preview.jpg" });

Hopefully you are able to help me with some example code that will generate the same tile sizes and structure.
