Lent 1AC++] I want to have ModelData data as a parameter to my graphics function, but it won let me. How can I get the coordinate information into the graphics function?
– When GLUT (the graphics system that we use) needs to redraw a window it calls the function that you mentioned in the graphicsfunction call. That function has to accept exactly 2 integers, because that’s how GLUT calls it – the integers are the current width and height of the window. The way we suggest you get the data into the graphics routine isn’t generally recommended, but it works.
