RSXGL pour PS3 fonctionne désormais parfaitement

Pour ceux qui ne savent pas, RSXGL est une librairie open source OpenGL pour Playstation 3 concoctée par Alex Betts qui prend en compte l'accélération 3D de la machine pour le développement des homebrews. Les devs en herbe peuvent désomais tirer partie des performances de calcul de la machine pour leurs projets.

La première version permettait d'obtenir un framerate d'environ 5 à 10 images secondes en 720P. On passe avec la nouvelle version à 50 ou 60 images secondes en 1080P, et cette dernière est parfaitement exploitable. Le téléchargement de la librairie se fait à ces adresses :

Voilà le message de Alex Betts :

Hi everyone!

When the PS3 homebrew scene started, a lot of people were complaining that it wasn’t possible to write 3D games for the PS3 because of its lack of OpenGL library.

Almost a year ago, Alex Betts thought he would tackle this problem and he started working on RSXGL… an implementation of the OpenGL 3.1 specification written from scratch targeting the PS3′s RSX. Anyone in their right mind would say that it’s impossible, that it’s too much work, but Alex spent the last year working on it, alone, until it became usable. You can read some news about it here.

For some reason though, no one used it to build their own apps. Maybe the status of the project was scaring them, it was said to be incomplete, there was no GLSL support, etc…

I am writing today to tell you that RSXGL is perfectly usable! It supports online GLSL compilation, as well as any feature you might want. As proof, I have written a new hardware accelerated engine for the EFL using RSXGL and it worked great! Alex and I spent a lot of time testing and fixing all the issues that were in RSXGL that were made visible by the EFL’s GL engine and I am happy to say that it’s working now. Expedite is able to run most of its tests at 50 to 60 fps on 1080p resolution (instead of the average of 5 to 10 fps it had on 720p before).

You can see performance tests right here (Running some tests from expedite) :

Please give RSXGL a try. Also, you can get the latest EFL version from my repository, which includes the gl engine for ps3. Now, any EFL application will be automatically hardware accelerated thanks to RSXGL. I hope we can see some new games (or old GL games being ported) soon!
