Is it possible to load symbols with content as needed, and not during the first loading? (when triggering image target or etc)
No. the whole symbol, project loads at time of the scan. Except for hosted files
Or other alternatives to quickly loading a project with a large number of different objects that are not displayed at the same time?
Downloading the rest of the content in the background?
Yes! Things like videos, audio and images can be hosted and will then be loaded after the Zap starts. This does NOT work for things like 3d models but you can host the images of the model!
Is it possible to detect other ZapCodes while working in a scanned project in order to switch to a new one by unloading the old one?
NO! but there are workarounds.
- If you know when you want to start a scanning you tell script the zappar app to start looking.
- Zappar has deep links that you can script to call the next project.
- With the new multiple tracking images you could use Destery code HERE
and use your zapcode as a tracing image. Then when seen you could call the deep link to that zap.
