Many moons back we were informed of the PlayStation 3 RSXGL graphic library which developer Alexander Betts was working on. However the project was not without it’s issues and was somewhat incomplete. Yesterday PlayStation 3 developer KaKaRoTo announced some great news regarding the subject and between him and Alex have corrected many bugs while implementing a hardware accelerated engine for EFL. With some great results…
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, by Text-Enhance”>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 by Text-Enhance”>new games (or old GL games being ported) soon!
