AR Image Targets
Before You Begin - Adding a New AR Image Target
Select an image to be used as a target for recognition.
Upload the selected image.
Drop the image, enter a title, and specify the image’s width either in real-world units or after printing.
Print the image.
Add AR Image Target in Scene
In the Over SDK, inside the AR Image Targets section, you will find a list of all the images you’ve previously added, as explained earlier in the setup process.
Each image in the list is displayed with its associated details. When you select an image from the list, a "Spawn" button will appear in the corresponding cell.
By clicking the "Spawn" button, the selected AR Image Target will be automatically added to your Unity scene, ready to be used for augmented reality tracking.
Display Objects with AR Image Targets
After successfully adding the AR Image Target asset to the scene, you can start attaching additional 3D objects to it. These objects should be added as direct children of the AR Image Target in the Unity hierarchy.
Any 3D objects you attach will be displayed in the scene whenever the camera recognizes the corresponding image target in real-time. This allows you to create immersive AR experiences, with your 3D objects appearing in the exact position and orientation relative to the recognized image. Be sure to position the 3D objects correctly in the scene for accurate alignment when the target image is recognized.
AR Image Target Behavior and Settings
We provide various behaviors and configuration options for AR Image Targets. These settings allow you to control how objects interact with the image target, including visibility, behavior upon loss of tracking, and scaling according to the target size. By leveraging these options, you can customize the AR experience to suit your specific needs and create dynamic, engaging content.
Movable
This behavior makes the associated object respond dynamically to the AR Image Target. The object will disappear when the target is no longer visible or tracked, and it will scale in size based on the target’s dimensions. This behavior is useful when you want the object to adjust to changes in the target’s visibility and size.
Static
The object spawns when the image target is first detected and remains fixed in the AR scene thereafter. Even if the target is lost or its size changes, the object will stay in place and retain its original size, offering a stable presence.
Custom
This behavior exposes the relevant fields so that the user can select and configure them according to their needs. This allows the user to fine-tune how the object behaves when the image target is tracked or lost, including the options for hiding, stopping, and scaling.
HideIfLost - the object associated with the AR Image Target will be hidden if the target is no longer detected by the system
StopIfLost - this option causes the object to stop functioning if the image target is no longer detected. After losing track of the target, the object cannot be re-detected or resume its previous behavior until the target is brought back into view
AssetFollowSize - the object will scale in size based on the size of the AR Image Target
