# Fologram for Hololens

## Setup

{% hint style="info" %}
Ensure your Rhino/GH machine and Hololens are on the same wi-fi network.
{% endhint %}

### Launch the Application

Launch the Fologram application through the Start Menu.

### Connect to Rhino/Grasshopper

Upon launching, you will be immediately prompted to scan a QR code to connect to a Rhino session.\
Look at the QR code generated in Rhino. Refer to [Fologram for Rhino](https://app.gitbook.com/@msd-makerspaces/s/next-lab/~/drafts/-MfG6p1XdjkJyDxzLYu7/augmented-reality/guides/rhino-and-fologram/fologram-for-rhino) page for more details.

### Model Placement/Snapping

Upon successful connection to Rhino, Fologram will be prompted to set the origin point of the holographic scene. This is tied to the origin point of the Rhino scene.\
\
The Hololens intermittently scans and maps a very rough 3D representation of your immediate environment. This allows you to roughly snap to surfaces. For the most part, this is perfectly acceptable. 

The Fologram Menu gives you further manipulation if required.

### Navigation and Interaction

Fologram only uses **\[air tapping]** for interaction.

## Fologram Menu

Tap and hold to bring up the Fologram Menu.\
This menu gives you access to the following functions:

| Menu Function        | Description                                                                                                                                                                                                                                                            |

| **Parameters**       | Control any sliders, toggles or buttons synced through Grasshopper.                                                                                                                                                                                                    |
| **Layers**           | Linked to Rhino layers, use this to toggle locks and visibility.                                                                                                                                                                                                       |
