Changes
An additional [[SYSCLS_ARCONTENTREFERENCE]] {{Version/WinXSince|3.4.0}} can be used to specify an UBIK Object that should be rendered instead of the detected AR-Marker. This enables Multi AR-Marker Rendering whereby one an the same UBIK object can be rendered in relation to multiple AR-Markers.
{{Attention|In order for a referenced object to be rendered, the detected AR marker object has to be additionally classified with [[SYSCLS_ARMARKER_DIRECTAR]]. And information such as distance, rotation, etc. is extracted from the detected object, not the referenced one. (This is critical for {{UBIK}} to render the same objects from different angles and distances.)}}
== Direct Augmentation ==
== AR-Marker Device Pose Estimation ==
If marked with the [[SYSCLS_ARMARKER_GEO]] classification, AR-Markers can be used for calculating the device pose once they are detected in the [[POI_View|POI View ]] (see [[AR-Marker_Device_Pose_Estimation|AR-Marker Device Pose Estimation]])
== Grouped AR Marker {{Version/WinXSince|3.8}}{{Version/XamarinSince|1.1| [[Version_1.1_Xamarin]]}}==
For scenarios where more than 1024 markers are needed, {{UBIK}} provides the possibility to group AR markers just like with Geo POIs. This means:
* Depending on the currently opened POI group, a scanned AR marker might not be displayed (if it's doesn't belong to that group);
* Within the same POI group, the 1024 unique marker limit still applies.
* All types of AR markers are subject to the grouping rules stated above, including:
** Directed augmented markers;
** AR content reference markers; {{Attention|Only the detected AR marker object has to the in the open group, not the referenced object.}}
** Geo AR markers.
{{Hint|POI groups can be switched manually, but also via e.g. QR marker scanning. In fact, one can scan a QR marker and an AR marker at the same time to switch to a certain group and then display the AR marker object within that group.}}
