Extends
This class extends others, you can call their methods on an instance of ofGLProgrammableRenderer too:
The OpenGL programable renderer is a renderer for OF that is built specifically to support both newer versions of OpenGL (3+) as well as supporting GLES, which is what you'll be using if you're running OF on an ARM Linux (i.e. Raspberry Pi), Android, or iOS device. There are a few key differences between OpenGL 3 and OpenGL 2 that are largely hidden from you by OF. You can still use the same methods for drawing, making meshes, uploading textures, and other drawing operations on the programmable renderer as you could on the direct pipeline, so you're not missing anything if you stick to the older pipeline. The most significant difference probably comes in writing GLSL shaders, since the syntax changes between the older implementation and the newer. One of the important things that the ofGLProgrammableRenderer adds is default shaders. That's right: every time you run your OF application, shaders are created and uploaded to the GPU without you even knowing it. There's also addition parameters that are automatically passed to the shader program that you can leverage if you're writing your own. Check out this chapter about OpenGL in the ofBook and this blog post for more information on using different OpenGL versions.
To initialize the ofGLProgrammableRenderer call ofSetCurrentRenderer() before you call ofSetupOpenGL() in your main.cpp file:
// say that we're going to *use* the fancy new renderer
ofSetCurrentRenderer(ofGLProgrammableRenderer::TYPE);
ofSetupOpenGL(1024,768, OF_WINDOW); // <-------- setup the GL context
After that, things should remain the same for you whether you're using the older ofGLRenderer or the newer ofGLProgrammableRenderer.
Alternatively, in openFrameworks 0.9 you can directly set the OpenGL version as follows:
// main.cpp (openFrameworks 0.9)
int main(){
ofGLWindowSettings settings;
settings.setGLVersion(4,5); /// < select your GL Version here
ofCreateWindow(settings); ///< create your window here
ofRunApp(new ofApp());
}

Documentation from code comments
Queries the current OpenGL matrix state
Returns the specified matrix as held by the renderer's current matrix stack.
You can query one of the following:
[OF_MATRIX_MODELVIEW | OF_MATRIX_PROJECTION | OF_MATRIX_TEXTURE]
Each query will return the state of the matrix as it was uploaded to the shader currently bound.
\param matrixMode_ Which matrix mode to query \note If an invalid matrixMode is queried, this method will return the identity matrix, and print an error message.
