Web SDK version changelog​

v5.6.3 - 2024/05/13​

Added:

  • Loading support for grayscale and palette PNG images.
  • Loading support up to 16 bit PNG images.
  • Generating mipmaps for textures in runtime when effect is loaded.

Changed:

  • Bump internal SDK version for loading DeepAR effect to 4.
  • switchEffect API now accepts also ArrayBufferLike, not just ArrayBuffer and string. This allows to directly load Uint8Array as an effect.

Fixed:

  • Environment HDR maps loaded through API (setEnvironmentMap) are now correctly interpreted as in linear space.
  • Tone mapping and HDR not working in full dynamic range on iOS. On iOS, SDK wrongly detected that 16 bit textures were not supported and fell back to 8 bit.
  • Fixed crash when additionalOptions parameter missing in initialization parameters.

v5.6.2 - 2024/04/29​

Added:

  • HDR support for glTF PBR materials
  • Added API setEnvironmentMap, setExposure, setToneMapping, setEnvironmentMapIntensity

  • Added API getClosestPointOnMesh, getTransformationBetween, setReadPixelsAsync.

v5.5.2 - 2024/01/19​

Changed:

  • The glasses face tracking stability is improved. Updated the rigid face tracking model.
  • By default, DeepAR rendering is now limited to 60 FPS. Before it was limited to 30 FPS. This can be changed with setFps API.

Fixed:

  • Using backgroundBlur with front camera doesn't work as expected.

v5.5.1 - 2023/12/22​

Changed:

  • Revert deepar.wasm is now compiled with simd support for better performance since it caused the SDK to crash on iOS Safari 16.3 and below.

v5.5.0 - 2023/12/21​

Breaking changes:

  • startCamera() API takes in an optional parameter mediaStreamConstraints which before expected only the video entry of the MediaStreamConstraints object. Now it takes the actual MediaStreamConstraints object.

Added:

  • Added support for WebP textures.
  • Lazy-loading of Javascript and Wasm modules.
    • DeepAR has a lot of functionality that may not be needed in each application and use-case. Some of that functionality is in Javascript and some is in Wasm modules.
    • DeepAR has been split into main and side Javascript and Wasm modules. Main modules are always loaded and side modules are lazy-loaded only when they are needed.
    • Main modules:
      • Javascript - 484 KB.
      • Wasm - 1.5 MB.
    • Side modules:
      • (JS) Background segmentation - 120 KB.
      • (JS) Glasses face, foot and wrist tracking - 919 KB.
      • (WASM) (Legacy) Face tracking - 818 KB.
      • (WASM) Scripting - 449 KB.
      • (WASM) Physics - 479 KB.
    • Note: All the sizes listed above are uncompressed files and those are not including the ML models and backends.
  • Added setFov() API for configuring the 3D rendering horizontal FOV. The default values are listed in the section below.
  • Added changePreviewElement() API for changing the previewElement which holds the DeepAR viewport.
  • Added WebGL2 Offscreen canvas to image pipeline. It is used whenever possible. Falls back to 2D Offscreen canvas or DOM canvas depending on what is available.

Changed:

  • Updated wrist tracking to V2.
  • Removed EngineDebug code and assets to improve WASM size and initialization.
    • Improved SDK initialization time by 80%.
    • Reduced WASM size by 0.3 MB.
  • deepar.wasm is now compiled with simd support for better performance.
  • 3D rendering horizontal FOV changes:
    • Mobile devices will use 85° FOV.
    • MacBooks will use 54° FOV.
    • Other will assume 90° FOV.
  • deepar.initialize() could be called several times in a row which would have undefined behaviour. So we check if initialize is called and throw if someone tries to call it before the initialization ends.
  • Removed most of the warnings that were outputted to console on DeepAR initialization.
  • Transition to native wasm exceptions rather then Emscripten emulated exceptions. Reduces wasm size b 0.2 MB.

Fixed:

  • Performance issues introduced in iOS 17 Safari private browsing due to privacy and fingerprinting updates.
  • Glasses face, foot and wrist tracking not working properly after the input camera/video resolution changes.
  • Glasses face tracking not able to initialize in some environments due to invalid OBJ file fetching.
  • Glasses face, foot and wrist tracking fails when the background in the input camera/video is static.

v5.4.4 - 2023/10/13​

Added:

  • optional RequestMode arguments for changeParameterTexture and backgroundReplacement.

v5.4.3 - 2023/09/21​

Fixed:

  • background segmentation regression.

  • touchEvent handling on mobile platforms.

v5.4.1 - 2023/08/17​

Reverted:

  • Reduced the initial size of deepar.js file from 1MB to 200kb. DeepAR Web will now lazy-load additional modules when it needs them.

v5.4.0 - 2023/08/11​

Added

  • DeepAR now takes in previewElement parameter at initialization. That is an HTML element like <div> which will be used for AR preview placement and sizing. It is intended to be used instead of canvas parameter which is now deprecated. This approach is now used so users do not have to manually crete and manage the canvas.
  • New method: getCanvas() which returnes the underlying canvas used for rendering.

Changed

  • Improved background segmentation performance.
  • [BREAKING CHANGE] Improved video recording. Videos are now produced in mp4 format that is compatible with the most devices. Audio capture from microphone is now available as well. The startVideoRecording() function is now async and returns Promise<void>. Before it was a plain function that returned void.
  • Reduced the initial size of deepar.js file from 1MB to 200kb. DeepAR Web will now lazy-load additional modules when it needs them.
  • The touchOccurred() function is now deprecated. DeepAR will now track the touches on the preview out-of-the-box.

Fixed

  • Freezing that occurred when the background segmentation effects were loaded for the first time.
  • Frozen camera on iOS Safari when using startCamera().

v5.3.0 - 2023/07/17​

  • Crash caused by effects with scripting.
  • Audio not playing if part of initial node in animation controller.

v5.2.0 - 2023/05/23​

Added

  • Wrist tracking.
  • Chrome extension support. Get in touch with us for more info.
  • CameraPermissionDenied error is now thrown when DeepAR requires camera from the browser, but the permission is denied.

Changed

  • Improved rendering performance with regard to mesh instances.

Fixed

  • Simple pendulum direction not consistent for front and back camera.
  • Sound not playing if part of the first state.
  • Crashing when passing null to changeParameter API for the component parameter.

v5.1.1 - 2023/03/31​

  • Fix front camera problems with beauty filters.
  • Fix camera sync issues.
  • Fix meshes using bones (but not face bones) disappearing when face not visible.

  • Now using WebGL2 canvas context for rendering instead of WebGL.
  • Fix non power of 2 textures not working.
  • Fix reduced depth precision when using postprocessing or render textures.
  • Fix eye position not working.

v4.1.0​

  • Updated the foot tracking API:
    • Added the initializeFootTracking method. Accepts a callback that is triggered when foot tracking is initialized.
    • Added the onFeetTracked callback which gets called when feet are tracked.
  • Greatly improved foot tracking's accuracy.

v4.0.3​

  • Fixed foot tracking when changing the video feed.
  • Render error message in case of too many polygons in effect.
  • Clean up logging.

v4.0.2​

  • Fixed foot tracking not working.
  • Added texture size uniform that is updated every frame for every texture.
    • In shaders it is accessible with TEXTURE2D_SIZE(sampler_name) macro.

v4.0.1​

  • Updated the Scripting API:
    • Added the Face Position component class.
    • Added trigger events and functions.
    • Fixed Debug.renderText() default color parameters.

v4.0.0​

  • SDK is now written in TypeScript and bundles appropriate .d.ts files with classes, types, methods and documentation.
  • SDK is now available on NPM npm install deepar.
  • Performance improvements.
  • 40% smaller JavaScript file and 20% smaller WebAssembly file.
  • New API:
    • setOffscreenRenderingEnabled - Force rendering on canvas even when tab is not focused.
  • Fix memory leak in processFrameRawPixels.
  • Fix caching u_modelNormal uniform when using the same material on multiple mesh renderers. More details: https://forum.deepar.ai/t/pbr-shader-web-sdk/71/16
  • Breaking changes:
    • DeepAR is now a class and is called with new keyword let deepAR = new DeepAR({ ... }).
    • Constructor parameters:
      • canvasWidth and canvasHeight - Passing these parameters has no effect anymore. In previous versions of SDK, these parameters would resize the canvas. You could change the canvas size with setCanvasSize() method. In new SDK, DeepAR will adapt to the canvas size. So you just need to set the size of the canvas. If canvas is resized, DeepAR will pick it up automatically.
      • numberOfFaces - This parameter has no effect anymore. DeepAR will track minimum number of faces according to the current configuration of loaded effects.
      • segmentationInfoZip - Path to the segmentation (background removal) model. This parameter is now changed to segmentationConfig.modelPath.
      • deeparWasmPath - Path to the deepar.wasm file.
    • Callbacks
      • You can provide callbacks in the constructor of the DeepAR class in the callbacks parameter.
      • Add, change or remove callbacks via DeepAR.callbacks property.

  • Introducing foot tracking as a beta* feature!
    • Allows you to easily create a shoe try-on app using the DeepAR Web SDK.
    • *Foot position component available only in DeepAR Studio 4.0-beta.
  • Breaking API changes:
    • Removed the libPath parameter.
    • Consequently, segmentationInfoZip should contain the full relative path to segmentation.zip.
  • Added new Dynamic UVs options in SDK and Studio.
    • For dynamic UVs you can choose between face and real options.
    • face option's behaviour is the same as it was before - UVs are adjusted for sampling the person’s face from camera texture.
    • real option adjusts the UVs so that the camera texture is sampled based on the real positions of the mesh vertices.
  • Fixed dynamic UVs not working for nodes that are not in face space.
    • Dynamic UVs now work for everything:
      • Nodes in orthographic layers.
      • Nodes in perspective layers.
      • Nodes in face space.
      • Nodes in face space with parent or child node transformations.
