          Description

          Description:

          When we git clone the examples repository indicated above and run locally
          the page ‘suzanne.html’, the model isn’t loaded and we receive the error
          "Could not load external document
          'file:/C:/Users/Alejandro/Desktop/TaskForce/3D-UI-XML3D/xml3d-examples/examples/suzanne/./suzanne.json':
          0 - ".

          This happens with any example we try to test locally. The expected output
          can be seen in the image XML3D_doesn’t_load_json_resources_1.png, as it is
          ran from the online demo page. The error can be seen in the image
          XML3D_doesn’t_load_json_resources_2.png.

            Hi,

            This is an expected behaviour of XML3D because of the CORS (Cross-Origin
            Ressource Sharing) handling in browsers. The browser refuses to access
            other local files referenced from a local HTML page because of security
            reasons.

            This can only be dealt with by going through a Web browser, where the
            browser adds the necessary HTML CORS-headers (which impossible with
            local files).

            Just to clear: The installation manual never suggests to locally copy
            and run the examples. And this behaviour is documented for XML3D.

            But we will check again and may make sure this more prominently visible
            in the installation manual to avoid similar user errors in the future.

            BTW, this still is ticket HELP-1003 right now.

            Best,

            Philipp

            Hi,

            We really appreciate the clarification made as we found the issue not very
            intuitive (comparing the resources to local css and .js files).

            We tested accessing the examples through a local XAMPP installation and
            everything worked as expected.

            The same suzanne.html file that we reported to fail can be seen
            successfully loaded from localhost in the image Model_loaded.png.

            Best regards,
