More OpenGLTOP cpp examples

Hi there,
Its an open call for everyone who feel comfortable with opengl and CPP top structure.

Im opengl newbie and Im looking for examples to do simple tasks with CPP top
like:
in this case retrieve texture as sampler for farther use in other tops or render the texture
on rectangle and push it father in the network .
trying to do it my self (creating 6 vertex rectangle with uv attributes … etc … )

and swim in the opengl sea of functions,its takes me a long time.

If someone wants to share their examples it will be good starting point for many
in my position I believe .

Other simple case where example could help .
