Hi everyone,
I need some help. I have to run a simulation where I have to create and save an image after regular intervals of time sequentially so that I can join those images to make a movie.

glutCreateWindow("XYZ") creates only one window at a time and also cannot be saved.

So can anyone tell me -
1. How to save an OpenGl image.
2. How to create multiple images.

I am really a beginner ..so please bear with me if my questions r very stupid.

Thanx!!
