I have written a program that graphs 2 and 3 dimensional functions as entered by the user. For the 3d functions, I would like the user to be able to manipulate the picture of the graph with the mouse. I wrote a routine to do this, but it is slow and choppy. Does anyone have any advise on how I could make it so the user could use the mouse to look at various views of the graph in real time? Thank you
