    Re: passing parameters in VC++

    I cannot understand what your exact question is but assuming you want to know how to register a display callback function here is my reply:

    Say you have a function Render() in which you write the rendering related code. This function is called whenever you want to render into the frame buffer.

    In order to register this function ( Or tell glut that this is the function to be called whenever the scene has to be rendered) you have to pass the function as a parameter to the glutDisplayFunc()

    ie: glutDisplayFunc(Render);

    hope this answers your query.
