Modifying layers and scale

Make sure you have been through the articles on preparing your own models and designing mixed reality experiences before continuing with this guide. We will use the Barcelona Pavilion (modelled by Christopher McAdams from Temple University and Plural) as an example since while the geometry is very simple we have the opportunity to work a lot with different materials and can create a sequence of spatial experiences (from 1:1 walk throughs to interacting with the geometry of the structure) that capitalize on the Mies van der Rohe's design.
You can download the model here:

Streaming the model to Fologram for Mobile
Make sure your PC and Mobile are on the same WiFi network, then open the Barcelona Pavilion model in Rhino. Type Fologram to open the Fologram plugin window, and click on the Connect A Device button to display your connection QR code.
Now launch Fologram on your mobile phone and scan the QR code to connect. Move your phone around the room until you detect a surface on the floor, then tap to place the pavilion model. I've placed the origin on the corner of the pool so you will either be standing in the water or right next to it. Don't fall in!
Playing with materials
I've already assigned a few materials to this model. Since we're connected to Fologram we will be able to preview and adjust the materials and texture mapping in real time in mixed reality and make sure everything is looking exactly how we want it. Go ahead and make a few changes - note that things like reflection aren't well suited to mixed reality as the real, physical environment isn't being reflected in your digital objects(yet).
Playing with scale
Try setting the scale factor to 0.02 (1:50) in the Fologram plugin window. Replace the model on a table surface using the Edit panel in Fologram. Try moving the model a little bit, then scaling it back to 1:1. This is can be a good way to rapidly move from one place to another with large models.

Interactivity and design games
It can be fun to interact with designs in mixed reality at both 1:1 and at scale. While the model is at 1:1, try walking inside the pavilion and moving the Onyx wall around by tapping on it and dragging. Maybe move it outside! How is the space changed?

At 1:50 scale, try taking the roof off the model (you can also do this by toggling the visibility in the Fologram Layers panel). How are the shadows changed? How is the experience different when you go back to 1:1?
Making changes in Rhino
Finally, try adding to the model in Rhino. Make a new sculpture for the pool, or design a new roof. Keep checking your design at 1:1 in mixed reality. Is the experience the same in Rhino and in Fologram? Try assigning different materials (concrete and timber work really well) and asking yourself the same questions. Don't forget to save your Rhino model (or save to your device if you have a subscription) if you want to keep your changes for later.
