From his blog: RSXGL Working and Usable

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...
 

RSXGL - The RSX Graphics Library for PS3 is Now Available

146w ago - Following up on previous news and the PS3 Linux kernel module, this weekend PlayStation 3 developer gzorin (aka Alexander Betts) has made available RSXGL - the RSX Graphics Library for PS3.

To quote: RSXGL - The RSX Graphics Library

This library implements parts of the OpenGL 3.1 core profile specification for the PlayStation 3's RSX GPU. It's suitable for use in programs that have exclusive access to the RSX, such as GameOS software (and is likely unsuitable for implementing a multitasking desktop, as the library
doesn't arbitrate access to the RSX).

Please see the STATUS file for up-to-date information about the current capabilities of this library.

Briefly, the following OpenGL 3.1 features haven't been implemented yet (the RSX is capable of supporting most of them):

  • Full GLSL support. Currently, GLSL and Cg shaders can be compiled offline and used with a OpenGL ES 2 style API.
  • Instanced draw commands.
  • Framebuffer objects and...

To quote: Well I am pleased to announce that RSX Driver for FreeBSD is released. The RSX driver is the product of hard work by durandal and glevand, who gave up many hours to accomplish this. So here you go, the link for the RSX driver: [Register or Login to view links]

On a side note, may I add that contrary to public belief for 5 YEARS, the RSX doesnt not rely on DMA to process graphics, but rather uses PPU instructions to push objects to RSX VRAM. So yeah another breakthrough by the team who scammed everyone. Gitbrew.

PS: To all those who started complaining about this noble effort to enable...

Below is some background on the PS3 RSX 'Reality Synthesizer' via [Register or Login to view links], as follows:

The RSX 'Reality Synthesizer' is a proprietary graphics processing unit (GPU) codeveloped by Nvidia and Sony for the PlayStation 3 game console.

Unless otherwise noted, the following specifications are based on a press release by Sony at the E3 2005 conference, slides from the same conference, and slides from a Sony presentation at the 2006 Game Developer's Conference.

Specifications:

  • 500 MHz on 90 nm process (shrunk to 65 nm in 2008 and to 40 nm in 2010)
  • Based on NV47 Chip (Nvidia GeForce 7800 Architecture)
  • 300+ million transistors
  • Multi-way programmable parallel floating-point shader pipelines
  • Independent pixel/vertex shader architecture

 

New PS3 Ships with More Efficient and Cheaper 40nm RSX GPU

500°
220w ago - Update: The new 40nm PS3 systems are now in the wild, as confirmed by SovietSlayer via [Register or Login to view links] at Fry's Electronics in Costa Mesa, CA.

In order to provide a more efficient and greener console, Sony is shipping new PS3 (CECH-2100A) entertainment systems which now include a cheaper 40nm (CXD5300AGB) RSX GPU that reduces energy output.

This reduction is down from the 90nm and more recently the 65nm RSX graphics processors and moves Sony one step closer to hardware profitability.

According to [Register or Login to view links] (translated by [Register or Login to view links] and confirmed by [Register or Login to view links]), the PlayStation 3's new improved RSX graphics chip also reduces the likelihood of the console being affected by the infamous PS3...
