Sorry, clarification: the tests are under sdk/tests/conformance/extensions/ in the Github repository. -KenOn Thu, Nov 10, 2016 at 2:52 PM, Kenneth Russell <kbr@google.com> wrote:Could someone please provide a conformance test for this extension? We don't have an ASTC pipeline conveniently in house.The existing compressed texture extension tests in https://github.com/KhronosGroup/WebGL under conformance/extensions/ should be a good starting point. Chrome already has this extension implemented behind the --enable-webgl-draft-extensions flag. We're basically waiting for a test to be able to validate the implementation and give a thumbs up.

I think that would be a great first step.On Thu, Nov 10, 2016 at 11:29 AM, Florian Bösch <pyalot@gmail.com> wrote:I did not record any device/webgl implementation exposing the ASTC extension (expected for draft extensions). The Samsung S7 lists astc support (though it seems to be spread across 3 extensions and one that isn't in the ES registry). Desktop linux driver for nvidia does not expose astc. iOS does not have astc.Since draft extensions are not exposed by default, I can't quantify what the current implementation status across platforms and UA vendors is. Could the UA vendors (apple, google, microsoft, mozilla) respectively comment on:
- What their implementation status is (and across which platforms)
- How well supported ASTC currently is on devices they see (by usage)
- If the spec is final
