  • Range for detecting an image target using an ImageTracker has been significantly improved.

Wikitude SDK 8.6

Release Date: 2019-07-11

Wikitude SDK 8.5

Release Date: 2019-05-23

New

  • Image Recognition engine now can work with jpg, png and zip files as Target Collection resource
  • Image Recognition engine accepts png's with alpha channel as target images and respects transparent areas

Improved

  • Image Recognition engine detects images from a larger distance
  • Image Recognition engine detects duplicate targets more reliably

Fixed

  • Fixed an issue where the extended range option was ignored for Image Trackers, resulting in shorter recognition distance
  • Fixed an issue where the property physicalTargetHeight was not set when using cloud recognition.
  • Fixed an issue where the application could crash in case image, object or instant tracking were used with no valid license key set.
  • Fixed an issue that caused model animations to sometimes not be restarted properly when calling start.
  • Fixed an issue that caused some videos to be rendered incorrectly.
  • Fixed an issue where the application could crash when setting distance, rotation or translation change thresholds at runtime.
  • Fixed an issue where the AR.ObjectTracker.onError callback was called with an invalid argument, resulting in a JavaScript error.
  • Fixed an issue where AR.ImageTracker callbacks might have been called although they were not set, resulting in a JavaScript error.
  • Fixed an issue where the FoV was calculated incorrectly, resulting in a wrong distance calculation.

Wikitude SDK 8.4

Release Date: 2019-04-09

Improved

  • Initial recognition for Object Targets is more accurate and stable
  • Improved recognition for image targets in difficult backgrounds

Fixed

  • Fixed an issue that prevented extended object tracking from working
  • Fixed an issue where 3D models were flickering when using Snap To Screen
  • Fixed an issue that caused landscape image targets to have incorrect augmentation scaling
  • Fixed an issue that caused errors in the JavaScript layer when using cloud recognition in combination with the onImageLost event of the AR.ImageTrackable
  • Fixed an issue that caused camera to stop after pause/resume using Plugins API

Removed

Wikitude SDK 8.3.2

Release Date: 2019-03-11

Fixed
