Specificationhttps://github.com/gpuweb/gpuweb/pull/4951 Summary Adds additional vertex formats not present in the initial release of WebGPU due to lack of support or old macOS versions (which are no longer supported by any browser). The 1-component vertex formats lets applications request only the necessary data when previously they had to request at least 2x more for 8 and 16-bit data types. The unorm8x4-bgra format makes it slightly more convenient to load BGRA-encoded vertex colors while keeping the same shader.

None Goals for experimentation Ongoing technical constraints None Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?No All platforms will eventually have support. Will immediately be available on Android, Android WebView, ChromeOS, Mac, and Windows, where hardware support is available. Linux is planned to have WebGPU support in the future, so this feature will become available when WebGPU does. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes WebGPU/WGSL have a conformance test suite (https://github.com/gpuweb/cts) that is regularly pulled into Chromium and part of the testing of Dawn/Tint in Chromium. While the CTS can be embedded in WPT, the WebGPU team opted to keep it separate in Chromium testing to use a customized harness for robustness and performance. https://github.com/gpuweb/cts/pull/4029 Flag name on about://flagsNone Finch feature nameWebGPUOneComponentVertexFormats Requires code in //chrome?False Tracking bughttps://issues.chromium.org/issues/376924407 Estimated milestones No milestones specified Link to entry on the Chrome Platform Status https://chromestatus.com/feature/4609840973086720 This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
