Re: [Chromium-dev] OpenGL-ES

[Mike H. <mho...@gr...>]

I agree that this usage scenario makes sense.  However, sort-last 
rendering like this doesn't require that many changes to Chromium for ES 
support.  For example, you wouldn't need much besides the glDrawPixels, 
glWindow, glRasterPos ES versions of those calls and dealing with the 
EGL stuff.

What I was suggesting is that using a cluster of embedded cores might 
not make sense.  However, if high powered chips running OpenGL-ES from 
say Sony or IBM made their way to market, then I could see the need to 
have Chromium be able to deal with OpenGL-ES commands.  It also might 
make sense to write a SPU that will translate from GL to OpenGL-ES so 
that off the shelf apps can be run on such devices.  However, as you and 
I have said, the biggest hurdle to the embedded space will be 
compilation and code size.

I didn't mean to discount the idea, I just wasn't sure what the end 
goals were.  I mean, we've supported other wacky ideas like PS2 and Xbox 
support...  ;-)
