Features

The application window appears as shown below, with menu items on the left hand side and model preview on the right hand side.

Example Render Streaming Output

Watch Folder

A watch folder can be setup in “C:\Program Files\Igloo Vision\Model Viewer Pro” so that a model will be automatically loaded after it has been copied into that folder. Create a new folder and call it “WatchFolder”.

Command Line Arguments

You can specify the path to a model file using a command line argument when starting up the Model Viewer. To do this, add the “-loadModel” argument, followed by the path of the model you want to open. e.g:
-loadModel "C:\ModelViewer\hintze_hall\scene.gltf"

Templates

Templates can be used to set specific rotation, scale or translation values to an object whenever it is imported. This is useful when a consistent transformation is needed in the workflow between Model Viewer and another application. To select a template simply use the drop down box and select from a existing one. To create your own, navigate to the StreamingAssets folder, and open an existing template, alter the values as necessary, and save it under a new template name. The template must be save with “config_” first. e.g: “config_[Your_Template_name].json”. The drop down box in Model Viewer Pro will auto populate with any files saved this way.

{
  "scale": {"x": 1, "y": 1, "z": 1},
  "rotation": {"x": 0, "y": 90, "z": 0},
  "translation": {"x": 0, "y": 0, "z": 0}
}

Controls

Movement - As is with every other Igloo application.

Right click / B button - Change movement mode. Pressing it once will update the cursor to correlate to the mode. Pressing it will swap to the next mode and loop back to the start when no more modes are available.

Standard - Aim where you want to go.

Wrap - Change the wrap position by pointing left or right.

Orbit - Move round the object in an orbit mode.

Streaming Setup

This requires setup in Igloo Control Panel as a custom browser called ModelViewerPro in custom_browers.json:

    "ModelViewerPro": {
      "name": "Model Viewer Pro",
      "url": "$remoteIP/receiver/index.html",
      "https": false,
      "icon": "$ai/image.png",
      "description": "Model Viewer Pro"
    }

And include ModelViewerPro in the apps list in the config.json:

    "apps": [
      "matterport",
      "streetview",
      "warping",
      "default",
      "modelViewer",
      "openStageControl",
      "blockade",
      "ModelViewerPro"
    ],

A web server will start automatically when you press start streaming which is located here:

C:\Program Files\Igloo Vision\Model Viewer Pro\Model Viewer Pro_Data\Managed\webserver.exe
