someone sent in a question earlier about doing something in 3D so i took a stab at it purely for educational purposes ( i'm not even sure that I understood the question actually ).
Unfortunately, persp gives me an error that I don't understand because it says "object y not found". I'm sending y in as a parameter to persp similar to what ?persp shows in one of oits examples so I must not be understanding something. the code is below. thanks.
