What do you like the wrapper do ? If you like to get easiest way to
run OpenGL you can take example skeleton<br>
from Imagination OpenGL-ES2.0 examples. They run in Fremantle, you just
need to compile them<br>
or then you can take Qt GLWidget as it is done in hellogl_es2 that is
part of Qt4.5 source.<br>
I also runs nicely in Fremantle.<br>
<br>
Good thing using Qt as a wrapper is that you can use full GL but you
can mix it with Qt UI widgets<br>
or QGraphicsWiew higer level drawing primitives.<br>

I am asking for a wrapper that will make it possible to port existing
OpenGL applications (mainly games) to Maemo 5+ without having to do any
real rewriting. I gave an example in my e-mail of an SDL game that uses
OpenGL.<br>
<br>
If your solutions will allow someone to port a game like Armagetron
Advanced without much effort, then that is what I'm looking for. If
this means rewriting the game / application, then that's not what I'm
asking for.<br>
<br>
A good way to know if your solution is what I'm looking for is to take
the Debian Lenny source code of Armagetron Advanced (<a
moz-do-not-send="true"
href="http://packages.debian.org/source/lenny/armagetronad"
target="_blank">http://packages.debian.org/source/lenny/armagetronad</a>)
and make a Qt / Imagination wrapper for it, then compile it to run on
Fremantle. If this takes a very long time, then this isn't what I'm
looking for. I'm looking for something that would be a drop-in
replacement for the OpenGL libraries for games like Quake2 or SDL games
like Armagetron.<br>

I hane not used SDL myself, so i hope that someone more familiar to it
can comment how much work is needed<br>
to make to use OpenGL-ES2 in maemo. I checked little bit Armagedonad
source code and it least looks<br>
that there is used OpenGL 1.x style primitives in eDisplay.cpp .<br>
<br>
OpenGL-ES2.0 != OpenGL 1.x . You can check
<a class="moz-txt-link-freetext" href="http://wiki.maemo.org/OpenGL-ES">http://wiki.maemo.org/OpenGL-ES</a> . To port applications that use
OpenGL-1.x API to OpenGL-ES2.0 need to use new API<br>
that you need to use if you are porting for desktop OpenGL 3.0 .<br>

You may think, "these aren't important, they're only games," but I
would disagree. And I'm not even a gamer.<br>

I don't think so, i think that games are very important applications.
They have a lot of users, there is lot of business with them .<br>
<br>
I was just saying that there is already many ways to take OpenGL-ES in
use in maemo. <br>
