Release 1.2.20

Important Service Updates

• SDK updated to version 1.2.20

Bug Fixes

• Pending promises and async C# API calls are now properly failed on graceful or ungraceful disconnect.
• Showcase: Fixed potential exception in script ClippingGizmoHighlight.cs when enabling the cutplane tool.

Sample Updates

• Samples now enable ForceTransparencyWritesDepth by default on VR devices.

Release 1.2.17

Important Service Updates

• SDK updated to version 1.2.17

Features

• Added TransparencyWritesDepth override flag to Hierarchical State Override Component API. This allows controlling depth writing for transparent materials on a scene-tree level and also adds support for depth writing for nodes rendered with See-through.
• Added ConversionID to the model metadata in arrAsset files.

API Changes

• Added Mesh.GetResourceStateAsync_Experimental, for querying whether connection to data source is Active or got Interrupted. This is meant to be used with remote streamed Point Clouds to check the connection status.

Release 1.2.16

Important Service Updates

• SDK updated to version 1.2.16
• Server-side spatial queries (SpatialQueryAabbAsync, SpatialQuerySphereAsync, SpatialQueryObbAsync APIs) are now substantially faster for models with many parts.

Point Clouds data streaming support

This service-side release introduced a new capability for converting and rendering point cloud files. It is recommended to re-convert all point cloud assets, however previous point cloud asset files will continue to work. Since this feature is integrated fully on the server side (both for conversion and rendering) an upgrade to latest client SDK is not required.

• Point clouds rendering now streams data directly from Azure storage (this applies for point clouds bigger than 2GB, for assets converted from today on).
• Point clouds conversion now supports up to 12.5 Billion points for a single asset. Note that multiple assets like this can be instantiated on the scene, together building scenes that surpass the 12.5 Billion unique points mark (on premium).

Bug Fixes

• Fixed spurious and random point clouds crash.
• Fixed point clouds physics crash when model is scaled down to zero.
• Fixed entity positioning problem after multiple reparenting operations (github issue #112).

Sample Updates

• Tutorial: Fixed typo in a function name BaseARRAuthentication.GetARRCredentials().
• Showcase:
  • Fix sharing stage placement not colliding with VR environment.
  • Fix VR environment floor level offset.

Release 1.2.12

Important Service Updates

• SDK updated to version 1.2.12

API Changes

A couple of new APIs have been added that help improving CPU performance and reduce the number of dynamic allocations per frame. Check them out below.

• Added the following new C# APIs that retrieve array/list results into a preallocated and reusable List<T> to reduce runtime allocations:
  • public void ObjectMetadata.GetMetadata(List<ObjectMetadataEntry> resultList)
  • public void RayCastQueryResult.GetHits(List<RayCastHit> resultList)
  • public void SpatialQueryResult.GetOverlaps(List<MeshComponent> resultList)
  • public void LoadModelResult.GetLoadedObjectsOfType(ObjectType type, List<ObjectBase> resultList)
  • public void LoadModelResult.GetLoadedResourceOfType(ObjectType type, List<ResourceBase> resultList)
  • public void MeshComponent.GetMaterials(List<Material> resultList)
  • public void MeshComponent.GetUsedMaterials(List<Material> resultList)
  • public void Mesh.GetMaterials(List<Material> resultList)
  • public void Entity.GetChildren(List<Entity> resultList)
  • public void Entity.GetComponents(List<ComponentBase> resultList)
  • public void RenderingConnection.GetRootEntities(List<Entity> resultList)
• Added the following APIs related to entity transform:
  • public Transform Entity.LocalTransform as an optimization to get/set all transform portions at once.
  • public Transform Entity.GlobalTransform to compute an entity's global transform.
  • public Matrix4x4 Entity.LocalToGlobalMatrix, a convenient helper function to retrieve the entity's global transform as a 4x4 matrix.
• Further C# changes:
  • Changed properties returning array or list to not use Linq.
  • Entity.VisitEntity(VisitEntityDelegate visitor) has been refactored to make use of the new APIs.
  • Entity.FindFirstEntity(EntitySearchDelegate pred) has been refactored to internally use Entity.VisitEntity(VisitEntityDelegate visitor).
  • Entity.FindComponentOfType<T>() has been refactored to use the native Entity.FindComponentOfType(ObjectType type) API, instead of iterating over all components on the C# side.

Migration guide

A new struct Transform has been introduced to serve the new entity transform related API functions. Inside Unity code, this may now collide with UnityEngine.Transform. To resolve this, just change existing occurrences to explicit UnityEngine.Transform.

Sample Updates

• Showcase:
  • Changed RemoteFocusProviderNoCollider to make use of the new APIs and make less GC allocation per pointer ray cast.
  • Various smaller improvements using the new APIs.
  • Swapped "AccountDomain" and "AccountId" in the Inspector UI in Showcase and Tutorial-Complete, so it's consistent with other sample projects and files.
• Tutorial-Complete:
  • Swapped "AccountDomain" and "AccountId" in the Inspector UI in Showcase and Tutorial-Complete, so it's consistent with other sample projects and files.

Release 1.2.10

Important Service Updates

Bug Fixes

• Unity: Fixed potential exception when releasing camera command buffers during shutting down Azure Remote Rendering.
