Major updates

Updates

General

• Added static CenterToRef for vectors 2/3/4 (aWeirdo)
• Added ability to view images (ktx2, png, jpg) to the sandbox. (bghgary)
• Added optional smoothed normals for extruded procedural polygons. (snagy)
• Added support for infinite perspective cameras (Deltakosh)
• Added ability to enable/disable ArcRotateCamera zoom on multiTouch event (NicolasBuecher)
• Moving button to shared uI folder.(msDestiny14)
• Moving additional components to shared UI folder.(msDestiny14)
• Added encapsulate and encapsulateBoundingInfo methods to BoundingInfo. (Tolo789)

Engine

• Moved all instance data from Geometry to Mesh such that the same Geometry objects can be used by many meshes with instancing. Reduces memory consumption on CPU/GPU. (breakin

Loaders

• Added support for EXT_meshopt_compression for glTF loader. (zeux)
• Increased KHR_materials_transmission render target texture default size. (Drigax)
• Changed glTF loader to remove empty animation groups if there are no animation channels loaded with the given options. (bghgary)
• Update glTF validator to 2.0.0-dev.3.3. (bghgary)
• Added support for KHR_xmp_json_ld for glTF loader. (Sebavan, bghgary)
• Added a OptimizeNormals option to the OBJ loader to smooth lighting (Popov72)

Navigation

• Added support for thin instances in navigation mesh creation (CedricGuillemet)
• Added recast.d.ts definition file for recast.js (CedricGuillemet)

Materials

• Added an OcclusionMaterial to simplify depth-only rendering of geometry (rgerd)

Inspector

• Increased float precision to 4(msDestiny14)
• Added support for sounds in the inspector (Deltakosh)

NME

• Increased float precision to 4(msDestiny14)
• Added ability to make input node's properties visible in the properties of a custom frame (msDestiny14)

GUI

• Added a FocusableButton gui control to simplify creating menus with keyboard navigation (Flux159)
• Added focus() and blur() functions for controls that implement IFocusableControl (Flux159)
• Added ToggleButton GUI control (kintz09)
• Added shorthand methods which set all padding values at once, named setPadding and setPaddingInPixels, to the control class (kintz09)

WebXR

• A browser error preventing the emulator to render scene is now correctly dealt with (RaananW)
• Added a way to extend the XRSessionInit Object from inside of a feature (RaananW)
• Added image tracking feature (RaananW)
• Pointer Events of WebXR controllers have pointerType xr (RaananW)

Bugs

• Fix issue with the Promise polyfill where a return value was expected from resolve() (Deltakosh)
• Fix ArcRotateCamera panning with axis decomposition (CedricGuillemet)
• Fix an issue with keyboard control (re)attachment. (#9411) (RaananW)
• Fix issue where PBRSpecularGlossiness materials were excluded from export #9423(Drigax)
• Fix issue when scaling is reapplied with BoundingBoxGizmo and GizmoManager (CedricGuillemet)
• Fix direct loading of a glTF string that has base64-encoded URI. (bghgary)
• Fix crash of some node materials using instances on iOS (Popov72)
• Fix the code generated for the NME gradient block (Popov72)
• Fix ssao2RenderingPipeline for orthographic cameras (Kesshi)
• Fix mipmaps creation in the KTX2 decoder for non square textures (Popov72)
• Fix detail map not working in WebGL1 (Popov72)
• Fix ArcRotateCamera behaviour when panning is disabled on multiTouch event (NicolasBuecher)
• Fix vertically interlaced stereoscopic rendering (RIG_MODE_STEREOSCOPIC_INTERLACED) not working (follow-up #7425, #8000) (foxxyz)
• Fix accessibility of BaseCameraMouseWheelInput and BaseCameraPointersInput. They appear in documentation but were not available for include. (mrdunk)
• Fix function creation inside regularly called freeCameraMouseWheelInput method leading to excessive GC load. (mrdunk)
• Fix clip plane not reset to the rigth value when using mirrors (Popov72)
• Fix lens flares not working in right handed system (Popov72)
• Fix canvas not resized correctly in a multi-canvas scenario (Popov72)
• Fix NaN values returned by GetAngleBetweenVectors when vectors are the same or directly opposite (Popov72)
• Fix 404 occurring on some pictures in some cases when using particle systems (Popov72)

Breaking changes

• List of breaking changes introduced by ou compatibility with WebGPU
  • ReadPixels and ProceduralTexture.getContent are now async
  • Shader support differences
• Use both mesh.visibility and material.alpha values to compute the global alpha value used by the soft transparent shadow rendering code. Formerly was only using mesh.visibility (Popov72)
• Depth renderer: don't render mesh if infiniteDistance = true or if material.disableDepthWrite = true (Popov72)
• Mesh.createInstance no longer make a unique Geometry for the Mesh so updating one Geometry can affect more meshes than before. Use Mesh.makeUniqueGeometry for old behaviour. (breakin)
• Ammo.js needs to be initialized before creating the plugin with await Ammo(); since Ammo introduced an async init in their library. (sebavan)
