Hi Gustaw, My understanding is that it's a combination of the awkward API, and dubious value. It's certainly not something that everyone is screaming for.
As far as mesa's implementation goes, I started on the parser changes and tests a while ago; I believe Ian was going to pick it up. I'm not sure whether he's had time to do much on it though. -- Chris On Mon, Nov 17, 2014 at 5:31 AM, Gustaw Smolarczyk <wielkie...@gmail.com> wrote: > Hello once again, > > This time, I would like to ask about the shader subroutine extension. > I believe this extension is not very popular, but is still needed for > GL4 compliance. > > What is the reason for its unpopularity? > Is it because one needs to reset subroutine uniform values after any glUse*? > Or it just didn't provide enough value? > Wouldn't it be good to implement uber-shaders (especially using > subroutine uniform array)? > > Is anybody actively working on it?
