Maemo5/Maemo6 indeed has gl es.

Problem is, code (or configure) is written for MacOS. I don't get it find libraries. It is not yet in own (packaged) library, but it is inside xscreensaver bundle.

Code:

wget http://www.jwz.org/xscreensaver/xscreensaver-5.16.tar.gz
tar xvf xscreensaver-5.16.tar.gz
cd xscreensaver-5.16
./configure --with-gles

We could also wait and see how pandora-camp handle it:

That's some rant the boy has. Particularly like the bit where he goes tonto at the suggestion of using GitHub

Let's wait for performance tests

Anyway,

but it is a great proof of concept that even full OpenGL 1.3 API on top of OpenGL ES 1.1 is doable in reasonable amount of time.

By the way, I love the way he writes and language he uses on his page :P

Seems like this will gain momentum in the weeks/months to come...

"If you don't agree with that, then please, get out of the software industry right now. Find another line of work. Please."

Sometimes i swear along such lines about customers...

Nevertheless, i'm unable to follow his objections against github et al/pro diff+email rant.

Supposedly all you need from that .tar.gz is jwzgles.h, jwzglesI.h and jwzgles.c, all in ./hacks/glx directory.

I guess I can, sort of. Some people (like me) have not been in active "development" for the last 10 years or so.

I for one, never even liked the autoconf stuff (just a good Makefile) and have never actually used a version control system, so if I were to continue developing some of my old stuff I would just continue using emacs and a Makefile.

Maybe someday I could start using git and put some of my old projects (e.g. lepton's crack

so I can learn how that all works!
