I have some questions regarding the function object: 1) I would like to read the data from a textfile to create the control points. How do I do that. The control points may be equally spaced apart. Porbleç: the list containing the values is quite large >500 values. what is the maximum number of control points possible 2) In case it is impossible to read all values, I was thinking of reading only the last 4 values of the list, every bang it should update for example: first bang reads values 1-4, second bang reads values 2-5, ... Is this possible?
