something like the NetBeans OpenGL Pack only with up to date sample projects?  Grin

This bootable CD would be for PS3 of course  Smiley
NetBeans OpenGL Pack with samples would be neat to deliver with it though for PC, to get people started.

Of course you can get access to it! How do you think PS3 developers write games??? What we'd like to see is basically an embeddable VM implementing just enough stuff to run - something like the one I used to use for my games, was about 2.5MB payload compressed with LWJGL. And LWJGL probably a much better fit than JOGL due to JOGL's extra complexity dealing with AWT (which PS3 doesn't need implemented!)

JOGL-ES is closer to PSGL than LWJGL. Under the "Graphics/Video" section of "Linux Kernel Overview" I found this:

"PS3 has a powerful graphic processing unit with high speed host connection. The GPU is connected to both HDMI and AV multi interface. Although the GPU is connected directly to CBE, no direct access by guest OSes to the GPU is allowed currently. Video mode/format setting is also the role of AV setting driver. PS3 Linux fb driver calls AV setting driver to setup video modes.

Currently X server uses virtual frame buffer to render its image. No hardware acceleration is supported under Linux. See the description above section."

If it is easy to access to PSGL, why don't you give a try?

Busy trying to make money, that's why! I don't have time to fart about doing pointless altruistic things that have no commercial value.

Under native PS3 it's probably not at all difficult if there were a good JRE.
But while there is a JRE on Linux, there's probably not even an OpenGL driver available under Linux, so under Linux it's not easy, if even at all possible without Sony's consent.

The main point is that (like you mentioned) it is not even *allowed* under a guest OS such as Linux, so there's no point to even try except for the sake of hobbyism and hackery.
A good official solution supported by Sony would be needed; a Linux solution is not usable as long as Sony (quite understandably) doesn't allow it.

It doesn't need even to be supported by Sony; it just needs to be a straightforward port of OpenJDK running natively on PS3 as an embedded VM. Whereupon the C++ component of your game simply becomes a JNI call to invoke the JVM and start running Java code. And a LWJGL port to PSGL to take care of the other stuff.

Maybe 'supported' was the wrong word. What I meant was more like 'allowed', or 'supported' like running other kinds of middleware under native PS3 is also 'supported', not necessarily the JVM itself has to be supported.
