This demo showcaes the ease of development of a Montage application by leveraging components, bindings, listeners, and the declarative approach and toolset promoted by Montage. It is intended for public distribution; though the history will be truncated prior to posting. Regardless, please keep confidential information to a minimum.

1. Install git
2. Install nodejs (http://nodejs.org)

Autopilot Everything:

3. sudo npm install minit -g && git clone [email protected]:declarativ/den-demo.git && cd den-demo && npm install && minit serve
4. Open the url reported by the previous command in a browser

Manual Installation:

3. After cloning this repository, cd den-demo
4. Run npm install
5. Browse to your clone as served by your local system e.g. http://localhost:8081/den-demo

Throughout the course of development run npm update to fetch the latest dependencies

NOTE: Prior to running npm update remove glTF-webgl-viewer from node_modules, (rm -rf node_modules/glTF-webgl-viewer)

• Run jshint on your code to ensure it conforms to our standards

• Make sure all commit messages follow the 50 character subject/72 character body formatting used throughout git

• Make sure commit messages start with uppercase present tense commands e.g. Prefer "Clear selection when clicking new button" over "Cleared selection when clicking new button"

• When adding or updating dependencies list the EXACT version of the dependency to minimize differences when building at different times. i.e. treat package.json as a shrinkwrapped dependency specifier

The following points about 3D do not cover - yet - Scene and View. Please ping @fabrobinet if needed.

A viewPoint is a node that contains a camera.
Just like any other node in the scene a viewpoint has transform that is potentially a target for an animation.

For example you can create & configure a viewPoint named "viewPoint0" - either in lumiere or by adding this serialization:

        "viewPoint0": {
            "prototype": "glTF-webgl-viewer/runtime/node",
            "properties": {
                "id": "node-camera001",
                "scene": {"@": "scene1"}
            }
        },

In this example:

• id refers to the id of a Node the glTF file
• scene points to the Scene object

Then this viewPoint is referred by a View as in:

        "view": {
            "prototype": "glTF-webgl-viewer/ui/view.reel",
            "properties": {
                "element": {"#": "colladaView"},
                "height": "768",
                "scene": {"@": "scene1"},
                "viewPoint": {"@": "viewPoint0"},
                "width": "674"
            }
        },

First of all, to get an idea of where are located the nodes that contains a camera (i.e viewpoints) you can look at the glTF file, as in :

        "node-Camera": {
            "camera": "camera_6",
            "name": "Camera",
            "rotation": [
                0.676486,
                0.390273,
                0.624542,
                1.49155
            ],
            "scale": [
                1,
                1,
                1
            ],
            "translation": [
                70.9776,
                -22.4153,
                50.3661
            ]
        },
        "node-LookAtBar": {
            "camera": "camera_5",
            "children": [],
            "name": "LookAtBar",
            "rotation": [
                -0.168108,
                0.559335,
                0.811717,
                3.62017
            ],
            "scale": [
                1,
                1,
                1
            ],
            "translation": [
                95.5895,
                -193.301,
                82.9342
            ]
        },

and so on...

At the time of writing this, the viewPoints for the "ride", i.e the animated ones are: node-camera001, node-camera002, node-camera003

The viewpoints without animation, just to "look at" a point of interest are: node-LookAtBar, node-LookAtBooks, node-LookAtFridge, node-LookAtLivingRoom, node-LookAtStairs, node-LookAtWindow,

The recommanded way to go to a static viewPoint is to:

• set the viewPoint on the view
• call the pause action on the view

Then to resume the ride:

• set the viewPoint with node-camera001 on the view
• call the play action on the view
