If you followed the previous tutorial on how to embed a ForgeJS viewer in your web page, you ended up with a viewer that just displays a black background because it has no configuration at all. So, now you'll want to add content. ForgeJS is meant to display 360° media. We will see how to configure the ForgeJS viewer to make the following project:

Two steps to achieve this:

  1. Create a json configuration file.
  2. Give the configuration to the ForgeJS viewer.

The json configuration

To customize the experience through a configuration, we will create a file that we named config.json. Many things can be declared in this configuration, but for the first one we will just add a scene with a 360° media to the project.

                "uid": "scene-0",
                "name": "My first scene",
                "slug": "my-first-scene",
                "description": "This is my first scene",

                    "uid": "media-0",
                    "type": "image",

                        "format": "equi",
                        "url": "path/to/equirectangular.jpg"

The configuration has a story object that contains an array called scenes with scene objects inside.

The scene object

  • uid - The unique identifier of the scene.
  • name - The name of the scene.
  • slug - The name of the scene that will be displayed in the url.
  • description - The description of the scene.
  • media - The media object that will be displayed on the scene.

The media object

The media object describes the 360° media that will be displayed on the scene background.

  • uid - The unique identifier of the media.
  • type - The type of media used by the scene.
  • source - The source object that describes the file to load by the scene media.

The media source

The media source is the file description that will be loaded by the media.

  • format - The format of the file. In this tutorial we use an equirectangular image, so the type is "equi".
  • url - The url of the file to load.

Loading the configuration

To load the project configuration, you have to give the url of the json configuration file to the FORGE.Viewer constructor as the second argument.
Now the javascript viewer creation will looks like this:

var viewer = new FORGE.Viewer("container", "config.json");
