Major updates

• New fancy forum! (Deltakosh)
• Inspector v2.0. Dev log (Deltakosh)
• Added support for parallel shader compilation (Deltakosh)
• Added Object Based Motion Blur post-process (julien-moreau)
• Added support for ammo.js as a physics plugin (Composite objects, motors, joints) (TrevorDev)
  • Added support for soft bodies, which are 3D softbody, 2D cloth and 1D rope, in ammo.js physics plugin (JohnK)
  • Added support for Convex Hull Impostor using ammo.js plugin (MackeyK24)
  • Added AmmoJSPlugin scene file loader (MackeyK24)
• Added support for WebXR (TrevorDev)
  • Added customAnimationFrameRequester to allow sessions to hook into engine's render loop (TrevorDev)
  • Added Camera customDefaultRenderTarget to allow cameras to render to a custom render target (e.g., XR framebuffer) instead of the canvas (TrevorDev)
  • Added webXR camera which can be updated by a webXRSession (TrevorDev)
  • Added webXRSessionManager to bridge xrSession to babylon's camera/engine (TrevorDev)
  • Added webXRExperienceHelper to setup a default XR experience (TrevorDev)
  • Added WebXREnterExitUI and WebXRManagedOutputCanvas classes to configure the XR experience (TrevorDev)
  • Added WebXRInput to manage controllers for the XR experience (TrevorDev)
  • Control WebXR camera rotation using parent container (TrevorDev)
• GUI:
  • Added control.useBitmapCache to optimize re-rendering of complex controls by keeping a cached version (Deltakosh)
  • Added new ImageBasedSlider to let users customize sliders using images (Deltakosh)
  • Added support for clipboard events to let users perform cut, copy and paste events (Saket Saurabh)
  • Added new ScrollViewer with mouse wheel scrolling for larger containers to be viewed using Sliders (JohnK and Deltakosh)
  • Moved to a measure/draw mechanism (Deltakosh)
  • Added support for nine patch stretch mode for images. (Deltakosh)
  • Added invalidateRect to AdvancedDynamicTexture to improve perf for heavily populated GUIs, works with shadows (TrevorDev)
• Migrated the code to modules and deploy ES6 npm packages (Sebavan)
• Added TrailMesh class. Credit to furcatomasz (danjpar)
• Support rendering to a multiview outputRenderTargetTexture with multiview engine component to improve performance for XR scenarios (TrevorDev)
• PBR (Sebavan):
  • Added clear coat
  • Added anisotropy
  • Added sheen
  • Added sub-surface
  • Added energy conservation through multiscattering BRDF
  • Added Inspector Debug Mode
  • Added Smith Height Correlated Visibility term (white paper)
  • Added SH Harmonics
• Added STL exporter (pryme8)

Optimizations

• Added an engine creation option to compile all shaders with medium precision (Deltakosh)
• Optimized effect reused for shadow maps (Deltakosh)
• Added support for scissor testing (Deltakosh)
• Improved shader precision detection (Deltakosh)
• Added support for bone matrix texture, allowing skeletons to use a texture instead of uniforms when possible (Deltakosh)
• Refactored of the SolidParticleSystem code for performance and code quality improvement (barroij)
• Added per solid particle culling possibility: solidParticle.isInFrustum() (jerome)
• Performance-oriented changes (barroij):
  • Prevented avoidable matrix inversion or square root computation.
  • Enabled constant-time removal from the transformNodes array and materials array of the Scene. As a consequence, the order of the element within these arrays might change during a removal.
  • Enabled constant-time removal from the instances array of a Mesh. As a consequence, the order of the element within this array might change during a removal.
  • Stopped calling Array.splice on the scene.meshes array and on the engine._uniformBuffer when removing an element. As a consequence, the order of the element within these arrays might change during a removal.
  • Added an option useGeometryUniqueIdsMap in the Scene constructor options. When set to true, each Scene isntance will have and will keep up-to-date a map of geometry per uniqueId. This is to avoid browsing all the geometries of the scene when a new one is being pushed. It also enables a removal of geometry in constant time. Disabled by default.
  • Added an option useMaterialMeshMap in the Scene constructor options. When set to true, each Material isntance will have and will keep up-to-date a map of its bound meshes. This is to avoid browsing all the meshes of the scene to retrieve the ones bound to the current material when disposing the Material. Disabled by default.
  • Added an option useClonedMeshhMap in the Scene constructor options. When set to true, each Mesh will have and will keep up-to-date a map of cloned meshes. This is to avoid browsing all the meshes of the scene to retrieve the ones that have the current mesh as source mesh. Disabled by default.
  • Added blockfreeActiveMeshesAndRenderingGroups property in the Scene, following the same model as blockMaterialDirtyMechanism. This is to avoid calling Scene.freeActiveMeshes and Scene.freeRenderingGroups for each disposed mesh when we dispose several meshes in a row. Enable by setting blockfreeActiveMeshesAndRenderingGroups to true just before disposing the meshes, then set it back to false just after.
  • Prevented code from doing useless and possible time consuming computation when disposing the ShaderMaterial of a LinesMesh.
  • Make a better use of the isIdentity cached value within a Matrix.
  • Make sure we browse all the submeshes only once in Material.markAsDirty function.
  • Added an Vector3.UnprojectRayToRef static function to avoid computing and inverting the projection matrix twice when updating a Ray.
• Added per mesh culling strategy (jerome)

Updates

GUI

• Added inputText.onKeyboardEventProcessedObservable (Deltakosh)
• Added button.image and button.textBlock to simplify access to button internal parts (Deltakosh)
• Added slider.displayThumb to show/hide slider's thumb (Deltakosh)
• Added grid.rowCount, grid.columnCount and grid.getChildrenAt() (Deltakosh)
• Added Control.AllowAlphaInheritance to let users control the way alpha is used (inherited or not) (Deltakosh)
• Added support for performing operations like select all, text highlight, delete selected in inputText (Saket Saurabh)
• Added inputText.onTextCopyObservable, inputText.onTextCutObservable and inputText.onTextPasteObservable to inputText (Saket Saurabh)
• Added AdvancedDynamicTexture.onClipboardObservable to observe for clipboard events in AdvancedDynamicTexture(Saket Saurabh)
• Added inputText.onFocusSelectAll to allow complete selection of text on focus event.(Saket Saurabh)
• Added mouse drag to highlight text in inputText (Saket Saurabh)
