ARGUMENTS

func
    The new motion or passive motion callback function.

DESCRIPTION
glutMotionFunc and glutPassiveMotionFunc set the motion and passive motion callback respectively for the current window. The motion callback for a window is called when the mouse moves within the window while one or more mouse buttons are pressed. The passive motion callback for a window is called when the mouse moves within the window while no mouse buttons are pressed. The x and y callback parameters indicate the mouse location in window relative coordinates. Passing NULL to glutMotionFunc or glutPassiveMotionFunc disables the generation of the mouse or passive motion callback respectively.
