Upgrading targets for SDK 4.x
The Wikitude SDK 4.0 introduces an updated format for the target collection. The new format improves the tracking quality and recognition phase. The updated format is not backward compatible with Wikitude SDK 3.x and can not be used in projects using Wikitude SDK 3.x. You can use the old format in projects using Wikitude SDK 4.x though.
To use the new format you need to re-create your target collection in the target manager and dwonload the .wtc file under the Download 4.x link. Put this .wtc file in your app and replace the previous one.
It is not possible to use a wtc 4.x file together with Wikitude SDK 3.x
| Wikitude SDK 3.x | Wikitude SDK 4.x | |
|---|---|---|
| wtc 3.x | supported | supported |
| wtc 4.x | not supported | supported |
Migrating targets from SDK 1.x
If you have been using a dataset from the Qualcomm Vuforia target management, please follow these steps to convert your ARchitect World to the new approach:
- Create a new project with the Wikitude target management tool and upload your targets (see instructions above)
- Create a target collection and store it in the same location as the previously used dataset
- In your ARchitect World, update the
AR.Trackerinitialization to point to the URL of your new target collection
