This is a basic (and probably a stupid) question, math is not my forte and I don't know much about math, in this site:
in the bezier curves column, specifically in the cubic bezier curve there are 4 points in a line namely p0 p1 p2 and p3.
In my case, I need to find the 2 control point in a line with a specific start and end point.
I can't understand where did the p1 and p2 came from.
and also, where could I get the tangent?
Please know that I am not a mathematician, I have a basic math knowledge and I'm poor at algebra and other kind of math, so please understand and explain as simple as you could do, I would appreciate it so much.
I have searched and found some links here as well, but I feel like I need a simpler answer than those (stupid right?) T.T
Please somebody help. And thanks in advance!
(I am trying to understand bezier curve better so I could make a function of that in objective c with specific number of points. And I'm assuming that the formula in that site will be helpful for my function as well.)
