A-Frame v0.9.0 Release Notes

Release Date: 2019-02-07 // about 5 years ago

  • 🐎 Performance improvements, WebXR support, Inspector updates!

    ✅ We continued to battle test A-Frame to produce native-like VR experiences and
    🐎 continue to add large performance gains. We have also introduced initial WebXR
    👌 support! Although the spec is heavily in flux and yet to have feature parity
    ✅ with WebVR 1.1, we had A-Frame get a head start to help test it out and smooth
    out the changes.

    Major Changes

    • ⬆️ Bump to three.js r101 on a branch with a few extra patches for WebXR support (f9f314).
    • 👍 WebXR support (#3875).
    • ✂ Remove <a-animation> in favor of new animation component (#3678).
    • ✂ Remove collada-model component (#3866).
    • ➕ Add renderer.colorManagement property (disabled by default) to accurately match colors against modeling tools, but may changes in scene colors when flipped on. renderer.gammaFactor will be set to 2.2. Call scene.renderer.systems.applyColorCorrection on THREE.Colors and THREE.Textures to normalize changes (#3757).
    • 🚚 Have raycasters only intersect against objects defined via .setObject3D. raycaster.objects should be specified (e.g., objects: [data-raycastable] or objects: .raycastable) because raycasting is expensive. raycaster.recursive property removed (#3980) but will default to be recursive only under objects defined via .setObject3D (#3652).
    • ➕ Add renderer component (#3757).
    • 🚚 antialias attribute moved to renderer.antialias.
    • Raycaster events such as raycaster-intersected no longer directly contain intersection data. Use .getIntersection function supplied in event detail or el.components.raycaster.getIntersection(el) to retrieve intersection data. Done to reduce garbage (a87e3b).
    • 0️⃣ Disable link portal appearance by default (link.visualAspectEnabled), link component defaults to purely to listening to an event to trigger navigation (#3743).

    🛠 Fixes

    • Frame-independent easing for wasd-controls to prevent judders during framedrops (#3830).

    • setPoseTarget to underlying object3D to fix issues with entities as child of camera (#3820).
    • ⚡️ Don't disable matrixAutoUpdate for tracked-controls outside VR (643fdc).
    • Render spectator view after VR submit frame (#3577).
    • 🛠 Fix mouse cursor events not being re-enabled on resume (#3904).
    • 👍 Allow components to write to camera Z rotation when look-controls enabled (9a78a)
    • Clear raycaster intersections when toggling disabled (#3594).
    • Postpone renderer until scene is appended to DOM (#3574).

    • 🛠 Fix magic window mode on Chrome (aaa3bf).
    • 🛠 Fix audio asset preloading (2a899c).
    • 🛠 Fix raycaster flatten to only include objects part of el.object3DMap versus arbitrary children (8809e7).

    • ⚡️ Update position, rotation, scale components when calling .setAttribute on them (#3738).
    • ⚡️ Update canvas bounds for mouse cursor on renderer resize (a4cf08).
    • 🛠 Fix controller reconnecting on Oculus Go and GearVR (dc8662).
    • 🛠 Fix playing sound on event with sound.on (#3844).
    • 🛠 Fix Chrome WebView (#3852).
    • 🛠 Fix raycaster not grabbing all entities when raycaster.objects is not set. But you should always set it (#3840).
    • 🛠 Fix WebVR polyfill buffer scale override (#3863).
    • 🛠 Fix text when used with other geometry types (#3909).
    • 🛠 Fix daydream-controls trigger not working with cursor by default (#3916).
