Helper arrow and watering can crashes #5

Open MrCsabaToth opened 1 year ago

These two object are not anchored to a GPS or even to a position in the AR Scene. Currently I constantly recreating them, maybe that's what causes it? Possibly I need to go low level and not even create an Anchor but a lower level non anchored object somehow?

This UX is disabled for now. For watering can we can use maybe an overlay of a POV 2D projected 3D watering can (a.k.a. 3D pre-render - not burdening the 3D engine). For the arrows I'll think about it. Even in AR examples with directional arrows the arrows anchored to a place. We'd need non anchored 3D objects! So we should probably just forget about anchors and wing it by ourselves.
