Specificationhttps://github.com/KhronosGroup/WebGL/pull/3222 Summary WebGL allows rendering into textures and renderbuffers of many different pixel formats (e.g, 8-bit, floating-point, sRGB-encoded, etc). The drawing buffer of WebGL (the buffer that is passed to the compositor) is 8-bit by default. This feature allows WebGL to configure the pixel format of this drawing buffer. This feature enables WebGL developers to: * avoiding an an extra copy convert their rendering to the default drawing buffer pixel format * draw content that has a more than 8 bits of precision The latter feature unlocks several additional applications * very wide color gamut content without loss of precision * medical applications which require >8 bits of precision * high dynamic range applications (when available) Blink componentBlink>WebGL <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EWebGL> TAG reviewNone TAG review statusNot applicable Risks Interoperability and Compatibility None. *Gecko*: Positive Feature authored by Mozilla. *WebKit*: No signal ( https://github.com/WebKit/standards-positions/issues/278) *Web developers*: Positive Positive feedback from several high profile web developers - 3D engines that use physically based rendering - image editing formats (especially for HDR) - medical imaging applications (which require >8 bit precision) *Other signals*: This feature's specification was authored by Mozilla. Ergonomics None. Activation No. Security None. WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? None Debuggability No additional debugging support should be needed. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?Yes The underlying technology (floating point textures) has almost universal support. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?No This feature is fully tested using WebGL conformance tests, which has been checked in. Flag name on chrome://flags Finch feature nameNone Requires code in //chrome?False Availability expectationFeature is available on Web Platform in less than a year following launch in Chrome. Adoption expectationSeveral specific partners have been using this feature being chrome://flags' "experimental web platform features", and intend to adopt this as soon as it is supported. Estimated milestones Shipping on desktop 122 Shipping on Android 122 Shipping on WebView 122 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
