<DIV><FONT face=Arial size=2>hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>thanks a lot, that sums it up..</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>i'll just comment on this then</FONT></DIV>
<DIV>>>can OpenGL ES be used on PC, x86 platform? emulator
maybe?<BR>>Probably, but I see no good reason beyond emulation and possibly
supporting very low end hardware</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>this is my reasoning,</FONT></DIV>
<DIV><FONT face=Arial size=2>in software, between two programs that produce
the identical output when 'instructed' with identical input, </FONT><FONT
face=Arial size=2>i say, the smaller one is that much, if not many times
that much "better" program and very often faster (which translates to
-better- as well)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>now, "better" can be defined in many ways, i dont
wanna go there.. but i see it simple as this:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>-if OpenGL ES is highly optimised for memory
consumption </FONT><FONT face=Arial size=2>and for speed so it has good
performance on 'week' hardware with little video/texture memory... well, how
fast will that than be on my fast desktop GPU with more memory than whole
computers used to have just a few years ago? ..if ES is smaller foot-print
or faster thats for me automatically better and what i want to use </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>i guess, that only leaves the question if it can
produce identical output.. now when i think about it, i see that my
question maybe doesnt make sense in a way.. that is, it would all come down to
DRIVER anyway, and if there is nothing "special" and different in ES
specs in way how you 'handle' graphic pipeline than ES is nothing more than
*subset* of OpenGL and you could use the same drivers you have now for your
card... on the other hand, maybe ES specs define some better way to
send/pack/unpack/draw/store primitives, more economical, faster? if so, is
that optimisation specific to that mini-GPU hardware? or maybe it can
be applied to desktop graphic cards as well.. which would,
then also be, quite a bit, a matter of DRIVERS too, again... those crazy,
crazy drivers..</FONT></DIV>
