  • exposed two new texture formats: PIXELFORMAT_R8 and PIXELFORMAT_RG8
  • both of these are supported on both WebGL2 and WebGPU, and are renderable
  • these are a replacement for PIXELFORMAT_L8 and PIXELFORMAT_LA8 that are WebGL only and not renderable
  • the old formats are kept for compatibility reason, as their behaviour is slightly different vs new formats (R is not automatically replicated into RGB when sampling and similar)

So should we deprecate L8 and LA8? Or alias them to R and RG?

We could deprecate them (hide the docs). I won't move that to deprecated as that needs a cleanup first.
Aliasing is not ideal (I started with that), as their behaviour is different.

LA8 format can be used by WebXR Depth Sensing as it can provide depth information either in R32F or LA8 formats.

Yep, exactly the reason I didn't just remove it, as I've seen it used there. Does it support RB8 format by the way?

It seems from the WebXR API we just get a typed array .. so I guess internally at some point we can switch this to use RG texture format, to be eventually compatible with WebGPU when XR is there. But for now this should still just work.

There are two paths: one is CPU that provides data as a buffer, that we use to construct a texture.
Or second path is GPU accelerated (e.g. Quest 3) that currently provides texture as R32F, but specs state that it can be LA8.

Unfortunately, removal of LA8 did break depth sensing for mobile.

Ah thank's for the update. I changed my mind during the PR lifetime and only deprecated those formats, but I see I failed to change back two lines, making these deprecated formats unusable. Following PR will fix it.
