This example shows how simple it is to use augmented reality to check whether parts are correct, orient design models to markers, or track physical tools even without much grasshopper expertise. Learning to work with markers and QR codes is a great way to begin to understand some of the more powerful computer vision tools in Fologram.
Here’s the 3 best ways to track live geometry in Fologram:
- Using Aruco Markers for tracking.
- Using Aruco Cubes for tracking.
- Using QR codes for tracking.
Templates for each of these tracking markers can be found on the Fologram website. Simply print them out, turn on tracking in in Fologram, and a live update of the location of each marker will appear in grasshopper. Move your marker around in front of your device and you will see the geometry from grasshopper following it live.
You might experience the tracked geometry jumping around or skipping frames and this can occur when your mobile camera either can’t clearly see the marker or has a poor map of the space you are working in. Check out this article to learn more about how to map your space for robust tracking.
