Developer gzorin has pushed RSXGL–a hardware accelerated 3D graphics library for the PS3–onto Github. According to the developer, RSXGL is to be used “in programs that have exclusive access to the RSX, such as GameOS software [...]“.
Readme:
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.

install info
RSXGL uses the GNU autotools for its build system and is distributed
with a configure script. It requires the following projects:
* [ps3toolchain](You must login or register to view this content.)
* [PSL1GHT](You must login or register to view this content.
NVIDIA's cgc shader compiler, from the Cg toolkit, is also required to
use vertex and fragment GPU programs.
The RSXGL library depends upon a toolchain that can generate binaries for the
PS3's PPU, and also upon parts of the PSL1GHT SDK. The sample programs also
require a few ported libraries, such as libpng, which are provided by
the ps3toolchain project. ps3toolchain recommends setting two
environment variables to locate these dependencies:
export PS3DEV=/usr/local/ps3dev
export PSL1GHT=$PS3DEV
RSXGL's configure script will use these environment variables if
they're set; if they aren't set, by default the script uses the above
settings. The PORTLIBS environment variable may also be set to further
control were the ported libraries can be found.
Anyway if these variables are set reasonably, then the following
commands should build RSXGL and its samples:
./configure --prefix=/location/of/rsxgl
make
make install
(Sample programs are packaged into NPDRM packages, but those packages
remain in their build locations; they don't get moved anywhere
relative to RSXGL's install path).
By default, configure will create non-debug builds with low
optimization settings (-O1). Other options are:
# Debug build, including assertions:
./configure --enable-debug
# Optimized build (-O3):
./configure --enable-ppu-optimize
The locations of the library's dependencies can be specified on the configure
command-line, too:
./configure \
--with-ps3dev=/usr/local/ps3dev \
--with-psl1ght=/usr/local/ps3dev/libpsl1ght \
--with-portlibs=/usr/local/ps3dev/portlibs
The configure expects to find versions of the gcc, g++, ar, ranlib,
and ld programs that target the PS3's PPU. It tries to find these in
$PS3DEV/ppu/bin, but the following environment variables can be set to
provide full paths to these programs to the configure script:
PPU_CC Location of C compiler
PPU_CXX Location of C++ compiler
PPU_AR Location of the ar archive utility
PPU_RANLIB Location of the ranlib utility
PPU_LD Location of the ld linker
The following environment variables can also be set to further
influence how headers and libraries are located:
PS3DEV_PPU_CPPFLAGS
PS3DEV_PPU_LDFLAGS
PSL1GHT_PPU_CPPFLAGS
PSL1GHT_PPU_LDFLAGS
PORTLIBS_PPU_CPPFLAGS
PORTLIBS_PPU_LDFLAGS
Currently two sample programs are built:
* src/samples/rsxgltest - A very simple test program whose contents and
behavior will vary. This program is mainly used to try out various
features of the library as they are developed.
* src/samples/rsxglgears - A port of an old chestnut, the "glgears"
program that uses OpenGL to render some spinning gears. This port is
based upon a version included in the Mesa library, which was itself a
port to OpenGL ES 2 after being handed down throughout the ages.
The sample can print debugging information over TCP, in the manner of
PSL1GHT's network/debugtest sample. src/samples/rsxgltest/main.c has
symbols called TEST_IP and TESTPORT which specify the IP address and
port number to try to connect to, and you can use "nc -l portnum" to
receive messages.
