Babylon.js/dist/preview release/what's new.md

3.2.0

Major updates

-Support for GPU particles (deltakosh)

• Improved building process: We now run a full visual validation test for each pull request. Furthermore, code comments and what's new updates are now mandatory (sebavan)
• Introduced texture binding atlas. This optimization allows the engine to reuse texture bindings instead of rebinding textures when they are not on constant sampler indexes (deltakosh)
• New AnimationGroup class to control simultaneously multiple animations with different targets (deltakosh)
• WebVRCamera now supports GearVR (brianzinn)
• New glTF serializer. You can now export glTF or glb files directly from a Babylon scene (kcoley)
• Babylon.js now uses Promises in addition to callbacks. We created several xxxAsync functions all over the framework (SceneLoader.AppendAsync for instance, which returns a Promise). A polyfill is also integrated to support older browsers (deltakosh)
• Introduced Projection Texture on SpotLight (lostink)
• Introduced support for local cubemaps (deltakosh)
• Added VideoDome class to easily support 360 videos (DavidHGillen)
• Added GlowLayer to easily support glow from emissive materials (sebavan)

Updates

• Tons of functions and classes received the code comments they deserved (All the community)
• Added particleSystem.reset() to clear a particle system (deltakosh)
• Added support for all RGBA orders (BGR, RGB, etc..) for the DDS loader (deltakosh)
• Improved SceneOptimizer to provide better adaptability (deltakosh)
• Improved scene.isReady() function which now takes in account shadows and LOD (deltakosh)
• New watcher configuration for VSCode. Now the task only compiles changed files (sebavan)
• Added new draw modes to engine (points, lines, linesloop, linestrip, trianglestrip, trianglefan) (benaadams)
• Added GUI Textblock.lineSpacing setter and getter to configure vertical space between lines in pixels or percentage values when working with text wrapping (carloslanderas)
• VRHelper now has onSelectedMeshUnselected observable that will notify observers when the current selected mesh gets unselected (carloslanderas)
• VRHelper now has onBeforeCameraTeleport and onAfterCameraTeleport observables that will be notified before and after camera teleportation is triggered. (carloslanderas)
• VRHelper now has the public property teleportationEnabled to enable / disable camera teleportation. (carloslanderas)
• VRHelper now exposes onNewMeshPicked observable that will notify a PickingInfo object after meshSelectionPredicate evaluation (carloslanderas)
• AssetsManager will now clear its tasks lsit from all successfully loaded tasks (deltakosh)
• Added documentation to WebVRCamera and VRExperienceHelper (trevordev)
• Introduced isStroke on HighlightLayerOptions which makes the highlight solid (PixelsCommander)
• (Viewer) There is now an option to paste payload instead of a URL for configuration (RaananW)
• (Viewer) Models can be loaded async using JavaScript (RaananW)
• VRHelper will notify now onSelectedMeshUnselected observable to subscribers when the applied ray selection predicate does not produce a hit and a mesh compliant with the meshSelectionPredicate was previously selected (carloslanderas)
• (Viewer) initScene and initEngine can now be extended. onProgress during model loading is implemented as observable. (RaananW)
• glTF loader now supports the KHR_lights extension (MiiBond)
• Added depth of field effect to the default pipeline (trevordev)
• The observable can now notify observers using promise-based callback chain. (RaananW)
• Added base64 helper functions to Tools (bghgary)
• Added createDefaultCamera and createDefaultLight functions to Scene (bghgary)
• Gulp process now supports multiple outputs when using webpack. (RaananW)
• (Viewer) Scene Optimizer intergrated in viewer. (RaananW)
• (Viewer) The viewer supports custom shaders in the configuration. (RaananW)
• Documented PostProcessRenderEffect, DefaultRenderingPipeline, BlurPostProcess, DepthOfFieldEffect, PostProcess, PostProcessManager, Effect classes (trevordev)
• SPS internal storage of each solid particle rotation matrix (jbousquie)
• SPS particle parenting feature (jbousquie)
• (Viewer) Introducing the viewer labs - testing new features. (RaananW)
• AssetContainer Class and loading methods (trevordev)
• KeepAssets class and AssetContainer.moveAllFromScene (HoloLite trevordev)
• (Viewer) It is now possible to update parts of the configuration without rcreating the objects. (RaananW)
• (Gulp) extra/external declarations can be prepended to final declarations during build. (RaananW)
• (Viewer) Model can be normalized using configuration. (RaananW)
• (Gulp) extra/external declarations can be prepended to final NPM declarations during build. (RaananW)
• GUI.Line can have its world position set from one end or the other (SvenFrankson)
• Added FOV system to background material for zoom effects in skyboxes without adjusting camera FOV (DavidHGillen)
• Improved glTF loader by using promises for asynchronous operations. (bghgary]
• Improved glTF loader performance by compiling materials in parallel with downloading external resources. (bghgary]
• Added unit tests for the glTF 2.0 loader. (bghgary]
• Added promise-based async functions to the SceneLoader, Scene.whenReadyAsync, and material.forceCompilationAsync. (bghgary]
• Added checks to VertexData.merge to ensure data is valid before merging. (bghgary]
• Ability to set a mesh to customize the webVR gaze tracker (trevordev)
• Add stroke (outline) options on GUI text control (SvenFrankson)
• Add floating point texture support for RenderTargetCubeTexture (PeapBoy)

Bug fixes

• setPivotMatrix ws not setting pivot correctly. This is now fixed. We also introduced a new setPreTransformMatrix to reproduce the sometimes needed behavior of the previous setPivotMatrix function (deltakosh)
• SPS solid particle .pivot property now also behaves like the standard mesh pivot. Former behavior (particle translation) can be kept with the particle property .translateFromPivot set to true (jbousquie)
• Texture extension detection in Engine.CreateTexture (sebavan)
• SPS internal temporary vector3 instead of Tmp.Vector3 to avoid possible concurrent uses (jbousquie)

Breaking changes

• Removed the unused PostProcessRenderPass class and extended postProcessingRenderingEffect to support multiple PostProcesses (trevordev)
• VertexData.merge no longer supports merging of data that do not have the same set of attributes. (bghgary]
• glTF 2.0 loader will now create a mesh for each primitive instead of merging the primitives together into one mesh. (bghgary]
