Re: [Public WebGL] Proposal to move WEBGL_compressed_texture_es3 to Draft



WEBGL_compressed_texture_es3 has moved to draft: https://www.khronos.org/registry/webgl/extensions/WEBGL_compressed_texture_es3/

Questions on missing error definitions and texturing functions have been attached to the extension text.

The ES 3.0.4 specification allows for compressedTexImage3D and compressedTexSubImage3D which are missing from this specification, should it be added?

WebGL 1.0 of course doesn't have tex[sub]Image3D. But it's possible that at some point we'd introduce an extension for it (the extension hasn't been formally proposed, but previously discussed unfavorably). I would propose not to define the tex[Sub]Image3D functions in this extension (i.e. leave that as it is) and if we would define the 3D texture extension for WebGL 1.0, we'd note its interaction with this extension (i.e. we'd have to add WEBGL_texture_3D because that one would also contain the symbols compressedTexImage3D and compressedTexSubImage3D). That's a bit messy of course, but it's likey we won't introduce 3D textures for WebGL 1.0 anyway, so the risk is probably small.

The ES 3.0.4 specification defines the errors INVALID_OPERATION, should it be added?
Anybody know the answer to that one?
 
The ES 3.0.4 specification defines the errors INVALID_VALUE for other cases than compressed size missmatch, should these be added?
