6D.ai SDK Release Notes - version 0.22.1

Release Notes
6D.ai beta SDK v0.22.1
Oct 1, 2019



Happy Tuesday!

This minor release introduces support for the devices announced at the September Apple event: iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max and 10.2" iPad.

Please note that the new iPads embed the 2016 A10 Fusion chip, which is significantly slower than the more recent chips found on the latest iPad Pro, Air and Mini. There are no changes on the neural network side; maps remain compatible with other clients running 0.22.x SDK across iOS and Android.


Sample Apps

  • Fixed crash in the Drawing sample of the Unity app when saving on iOS 13
  • Fixed mesh alignment issue in the SceneKit app when in portrait mode on iOS 13

Known Issues

The following issues will be addressed in future releases:


  • Difficult environments (white walls, glass, mirrors, metallic or shiny surfaces) sometimes produce irregularities like mesh shards flying in mid-air.


  • Outdoor relocalization is currently impacted by the accuracy of GPS on the phone. In situations where the phone GPS varies greatly, relocalization may not occur properly.
  • Relocalization is sensitive to device orientation. E.g. relocalization may not work in portrait mode if the space was mapped in landscape mode.


  • Each SixDegreesSDK_Initialize() / SixDegreesSDK_Stop() cycle leaks between 2 and 3 megabytes.
