Re: [Public WebGL] OES_draw_elements_base_vertex extension to WebGL?

I suspect we'll find that the performance is about the same, but we should definitely look into whether the support would be any wider

Thanks Jukka for the feedback. Yes I was also considering adding the non-base-instance version entry point glDrawElementsBaseVertex as well to the extension based on some first round profiling. Your suggestion gives me more motivation to try this out. I will make a profiling comparison and bring this up in the WebGL working group meeting.

Hello all,

here's another extension that has come up in conversations:


That extension would help pack a lot of static indexed geometry into a
single vertex+index buffer.

There does exist the draft extension
, which could be used for this, by placing instanceCount=1,
baseInstance=0, though I wonder if it would be possibly more optimal
or more widely supported to specifically enable the non-instanced
variant as a glDrawElementsBaseVertex() function?
