2020-11-11
REST API: Proper URI identifiers
REST API: new endpoints for image capture and on-server localization, where the image payload can be sent as binary instead of a Base64-encoded string (smaller filesize -> faster uploads)
Immersal Mapper / REST API: Use tracker poses-feature for map construction (beta)​

Samples: Magic Leap localization support and a reference Unity project, https://github.com/immersal/arcloud-sdk-samples/tree/magicleap) ​
Core: OnPoseFound and OnPoseLost events in ImmersalSDK.cs
, OnFirstLocalization event in ARMap.cs

Immersal Mapper: Updated UI
Samples: Restructured Unity core package and the Unity sample project. ARMap.cs
, ARLocalizer.cs
, and other essential scripts are now part of the core package. This should make future SDK updates to new versions easier.

SDK v1.4 was released to closed testing earlier. After a round of updates and new features, we decided to fast-track v1.5 out for public release.
New v1.5 (technically v1.4) maps are not supported by older SDK versions.
Server/Developer Portal: Support for private and public maps.
Server/Developer Portal: Sending/copying maps between accounts.
Server/Developer Portal: Search for public maps and filter by GPS coordinates or user accounts.
Server/Developer Portal: SHA256 hashes for new maps.
Server/Developer Portal: Reset the private developer token.
Samples: Huawei AR Engine support​
Samples: ARLocalizer.cs
has a new toggle to reset filtering when the last localized map id changes.
Samples: Graph-based navigation sample.
Immersal Mapper: Android now properly requests for location (GPS) permissions.
Server/Plug-in: Generated maps are now up to 80% smaller.
Server/Plug-in: Map file format is not compatible with v1.3 anymore. v1.5.0 plugin can still load maps done with earlier SDK versions. Server/Plug-in: Both the localization accuracy and speed have been improved. Plug-in: The native plugins are now 75% smaller.
Developer Portal: Updated version of the Developer Portal to support new features.
Samples: ARlocalizer.cs
lastLocalizedMapId
variable made public.
2020-02-07
New v1.3 maps are not supported by older SDK versions.
Developer Portal: v1.3 breaks map file format forward compatibility. Old maps are stored in a separate legacy v1.2 Developer Portal. Maps are not carried over to the new version.
Developer Portal: A new sparse state in map construction. Maps are generated faster as you can now download the .bytes file and sparse .ply point cloud before the dense mesh is computed.
Server: On-server localizer now also accepts RGB24 .png images in addition to 8-bit grayscale ones for easier headset integration.
Plugin: Visual GPS support. If a map contains GPS data, the localizer will return WGS84 lat/long/alt coordinates with a successful localization.
Samples: Mapping App now has a GPS toggle. When on, captured images contain GPS coordinate data which is used in map construction. Also, maps in the map list are filtered with a 200-meter radius from the current location.
ARLocalizer.cs
Burst mode now runs when the app enters the foreground.
ARLocalizer.cs
and ARHelper.cs
Fixed rotation for different screen orientations so portrait/landscape/auto now work.
Plugin: Localizer now returns -1 mapID if no maps are loaded.
Immersal AR Cloud SDK name to Immersal SDK everywhere.
Developer Portal: Dense meshes are now more detailed.
Plugin: Localizer now returns the actual mapID from the Developer Portal instead of a mapHandle unique to the session.
Plugin: Map file format changed. Old .bytes files continue to work in v1.3, but new maps will not work in older versions.
Samples: Updated project to Unity 2019.2.20f1.
Samples: Added dependancy to AR Foundation 3.1 preview, because some scenes have AR Occlusion Manager attached to the AR Camera. Older versions of AR Foundation continue to work.
Samples: Updated NavigationSample scripts.
2019-10-16
Developer Portal: Map stitching. You can select multiple maps and combine them into one new map (assuming the maps have overlapping features).
Samples: Mapping App can now restore any old map's source data to the workspace from the map list.
Samples: Mapping app can also delete maps from the map list directly.
SDK: Mapping performance improvements.
SDK: REST API updated.
Samples: The "AR Cloud space" rotation and position can now be gotten from ARSpace.cs
instead of ARLocalizer.cs
, which was buggy anyway and returned only the first map's pose, thus giving incorrect results when using multimaps.
Samples: Navigation and multiplayer samples fixed to work with multimaps.
Samples: UI fixes all over.
Samples: Updated project to Unity 2019.2.8f1 and AR Foundation 3.0.0 preview.3, should continue to work just fine with older versions.
Developer Portal: Updated EULA.
