Re: [Public WebGL] Need to spec range checking for WebGL ANGLE_instanced_arrays?



Isn't range checking of draw commands via instanced arrays quite a bit different than normally because vertex attrib pointers can wrap around to the beginning?

Hi all,

I noticed that there doesn't seem to be a specification for range checking of buffer indices as it comes to ANGLE_instanced_arrays WebGL extension. The main spec naturally only talks about the vanilla drawArrays and drawElements, and the extension spec doesn't really mention this. Should we add a mention to the extension spec at http://www.khronos.org/registry/webgl/extensions/ANGLE_instanced_arrays/ , or is the interpretation the instanced variants are somehow implicitly covered by the range checking section in the main spec?
