Wikitude SDK ODG Release Notes

Wikitude SDK JavaScript API 6.0.1

Release Date: 15.02.2017

Fixed

• Fixed an issue where AR.hardware.sensors.enabled had no effect
• Fixed an issue where AR.GeoObjects could not be created without options
• Fixed an issue where the AR.GeoObject isVisible() function would not return a proper value when used in combination with AR.RelativeLocations
• Fixed a memory issue when instant tracking is used in combination with HD frame rendering (not recommended)
• Fixed a watermark rendering issue that occured after the application was paused/resumed
• Fixed an issue where calling the AR.TargetCollectionResource cancel function had no effect

Wikitude SDK JavaScript API 6.0.0

Release Date: 25.01.2017

New

• The new instant tracking feature allows users to place augmentations without any markers in any surrounding. Instant tracking uses Wikitudes own SLAM-based 3D engine.
• Added advanced camera settings like HD and 60 fps camera rendering and a manual focus control (Camera 2 API)
• Unified computer vision related class names
• Multi-touch gestures allow the interaction with augmentations. Available touch gestures include dragging, scaling, rotation and panning.
• Added 3D positioning for 2D augmentations
• Added an option to enable/disable billboard behavior for AR.Drawables

Improved

• Updated target collection format (.wtc) which improves the robustness and performance of 2D image recognition.
• Extended tracking improved significant using the new SLAM technology
• Behaviour of removing plugins at runtime - lifecycle callbacks are now called properly
• Plugins now receive a call to surfaceChanged in case the device was rotated while the application was not active.
• Calling the start function of AR.ModelAnimation in case the referenced 3D model is not loaded yet actually starts the animation as soon as the 3D model is loaded
• Add toast output if media player activity is not declared in manifest
• Add javadoc.jar to the Android SDK to integrate into Android Studio

Fixed

• Fixed an issue where the SDK could crash in case a lot of AR.Trackable2DObject are generated in a loop and immediately destroyed
• Fixed an issue where the AR.Model onLoaded callback would be called although the 3D model is actually rendered for the first time in the next frame
• Fixed an issue where the SDK was not working using multiple AR views

Wikitude SDK 5.3.1

Release Date: 24.11.2016

Fixed

SDK

• Fixes an issue where AR.CloudTracker would not work when using input plugins
• Fixes an issue where the camera could not be resumed after it was stopped through AR.hardware.camera.enabled = false
• Fixes a crash if AR.BaseTracker are destroyed with AR.Trackable2DObject's still attached to it
• Fixes an issue where the AR.Trackable2DObject onEnterFieldOfVision trigger would not be fired if the trackable was created after it's AR.BaseTracker already recognized a target
• Fixes an issue where proguard for an app was not able to exclude wikitude sdk classes
• Fixes an issue where a video opened via AR.context.openInBrowser(url) was not destroyed after leaving the activity

Wikitude SDK 5.3.0

Release Date: 13.09.2016

New

SDK

• Android 7.0 Nougat support
• New InputFrameRenderSettings options for Plugins API
• A new include for the architect.js to prevent mixed content errors in https environments

Fixed

SDK

• Fixes an issue where AR.CloudTracker would not be able to send proper server requests
• Fixes an issue when enabling and disabling the camera via AR.hardware.camera.enabled
• Fixes an issue when resolving relative paths inside the JS library
• Fixes an issue where the SDK could crash if a different Architect World is loaded and the previous one used cloud tracking
• Fixes a rare crash in the 3D Tracking engine

Improvements

• Improved memory handling of 3D models
• Improved support for different Camera2 API implementations for Input Plugins
• Improved and aligned behaviour of cache handling
• isDeviceSupported now returns a more detailed list which requirements are not met

Fixed

SDK

• Updates OpenSSL to version 1.01r
