Interpretation of statements

Hi all,
There are some statements which I don’t quite understand and unable to interpret correctly for my Opengl assignment. Please help.

Statement 1 : What does it mean by “…invoking animation of the shape transformation from first surface to the second one and backward.”

Statement 2 : “…the program renders more than 2 surfaces.”

I don’t get it more than you do, can you just post the whole assignement so that we know what you are suppose to do in general?

Maybe the person who gave you the assignment can answer that for you :O)
