Hi!!!
I’m making a code port from WebGL to OpenFrameWorks. It is based on excellent lessons at www.learningwebgl.com. You can think…oh no! nehe lessons again 
but this time is a bit diferent:
-a modern openGL approach using fastest techniques like VBO + GLSL (no more glBegin-glEnd).
-avoid deprecated GLSL like ftranform(), gl_ModelViewMatrix, gl_Vertex, gl_ModelViewProjectionMatrix, gl_Normal etc…
-using OF addons (ofxShader,ofxMatrix4x4).
Well too many words. You can grab the code here. (made with xcode). I hope you like it.
