I tried to calculate the inverse Modelview, but what is gl_ModelViewMatrix ? It is definitively not the same like glGetFloatv(GL_MODELVIEW_MATRIX,m). (of course I don't do anymore transformations after I call glGetFloat)
OpenGL seems to make an additional transformation before sending it to the Shader. What is this transformation ?
