I am looking for logic to show various location markers based on area visible through camera view of a device on android. Something similar to attached image. I know following things
After searching a lot found following things An SDK which is open https://artoolkit.org/documentation/doku.php?id=1_Getting_Started:about_installing
and these examples https://github.com/tvbarthel/ChaseWhisplyProject https://code.tutsplus.com/tutorials/android-sdk-augmented-reality-location-distance--mobile-8004
Hope this helps someone else as well.
