Re: [Public WebGL] EXT_pvrtc_sRGB extension to WebGL?



FYI: collaboration with Apple's WebKit team is underway to support the ETC1 and ETC2 compressed texture formats in https://bugs.webkit.org/show_bug.cgi?id=197900 . ASTC support is already in WebKit but currently behind a flag; another goal is to take it out from behind that flag.

These devices also support ETC2-sRGB via OpenGL ES 3.0, but the WebGL 1/2 extension is not exposed yet in Safari. Would that work for you? Overall we are trying to focus on having good support for a smaller set of formats (ETC2 on mobile, S3TC on desktop, optionally ASTC) if other formats aren't necessary.

Hi all,

I wonder if there have been any prior discussions about adding
https://www.khronos.org/registry/OpenGL/extensions/EXT/EXT_pvrtc_sRGB.txt
support over to WebGL side?

That would help towards enabling Unity support for linear color space
rendering on Apple iOS devices.

Cheers,
Jukka
