When you launch Fologram and connect to Rhino, you have the option to place your model in the physical space that is mapped out by the HoloLens. If you wish to accurate place a model or if multiple people need to view the same model, Fologram QR Codes can be generated to assist.
In Rhino, execute the FologramQR command. You will get a prompt that will ask you to set your origin, x axis direction and y axis direction. One can set this to be the same as your Cplane in Rhino. After that, you will be asked to provide a label for the QR code.
You can also select the paper size that the QR code will be printed in and the save folder. Print this QR code at actual size without any scaling. Fologram uses the scale of this QR code to assist in model placement, discrepancies in size will result in incorrect mapping.
Place your QR code image at the desired location. This will not be the anchor for your Rhino viewport.
In the HoloLens, pinch and hold to bring out the menu. At the top of the list, you will see the command Snap to QR Code . Select this and now a target window will appear, asking you to look at the printed QR code that you have placed on a surface. Simply look at it and the model will align to the QR code.
Remember that you can adjust the scale of your model in Rhino and it will automatically update to Fologram in the HoloLens. This can be helpful if your hologram model needs to fill an entire room or you have a part that will need to align with a physical tool. Moving the printed QR code around and re-snapping to it is also an effective way to realign your hologram model.
