  • GeometryData now stores the original geometry DataChunks instead of just number arrays. This change was the basis of a larger update we made to facilitate larger model loading by minimizing memory allocation during startup and load - ViewerEvent.Busy has been removed and it’s no longer emitted
​
May 2025
  • get clippingVolume from SpeckleRenderer now returns an OBB - set clippingvolume from SpeckleRenderer now accepts both Box3 and OBB - all intersection methods from Intersections now accept both Box3 and OBB as bounds argument - expandBoxRelative from World now accepts both a Box3 and a OBB - requestUpdate from SectionOutlines extension now takes an optional force argument that forces an update
​

  • Loader’s resourceData changed from string | ArrayBuffer to unknown to allow each loader to define it’s own resource data type
​

  • SmoothOrbitControls’s constructor changed. It no longer takes a Scene and Intersections, but only a SpeckleRenderer
​
November 2024
  • Loader’s resourceData changed from string | ArrayBuffer to unknown to allow each loader to define it’s own resource data type - SmoothOrbitControls’s constructor changed. It no longer takes a Scene and Intersections, but only a SpeckleRenderer
​
October 2024
  • Entire rendering pipeline got a massive update and it now allows for free user customization as well as user defined passes - pipeline accessors added to SpeckleRenderer. This allows for user defined rendering pipelines - pipelineOptions accessors removed from SpeckleRenderer - PipelineOutputType removed. The pipeline’s result now depends on the pipeline’s pass configuration - DynamicAOPassParams and it’s default removed - StaticAoPassParams and it’s default removed and replaced by ProgressiveAOPassOptions - A series of pre-defined rendering passes as well as entire rendering pipelines have been added
​

  • All input mesh vertex colors are now treated as sRGB
​
July 2024
  • NearCameraCalculation type option added to CameraController option. - UpdateFlags.RENDER no longer resets pipeline. Added UpdateFlags.RENDER_RESET which forces a pipeline reset
​

​
May 2024
  • Vector3Like replaces VectorLike in the arguments of transformTRS in BatchObject - SpeckleLoader no longer takes a priority argument in it’s constructor - addRenderTree from SpeckleRenderer now takes a RenderTree as an argument instead of a RenderTree id - getRenderTree is now overloaded with a version with no arguments that never returns null - intersect and intersectRay arguments have been moved around and both are now overloaded
​
April 2024
  • Asset now has a mandatory id field - getEnvironment and getTexture from Assets now only accept Asset as argument - The concept of Providers has been removed entirely - CameraProvider has been replaced by SpeckleCamera - CameraControllerEvent renamed to CameraEvent
​

The introduction of viewer API 2.0 into our stable channel. The changes to the API itself are extensive and there is no point for a step by step guide, as what was previously known as API 2.0 will become the single supported viewer API moving forward.
