I'm implementing b-spline curves and there is one last point I'm not understanding.
What doest the parameter (t or u in most explanations) range correspond to in visual terms?
I understand how to calculate the values to compute C(t) = ∑ Bi , p (t )Pi but I don't understand how to vary t (or u).
What I want is to know what are the points between P1 and P2, how do I do that by varing the t?
If I understand correctly, t is just value, where t = 0 indicates P1 point, while t = 1 is P2 point, most likely t = 0.5 will be in the middle between those points. If you want to gather points between P1 and P2 just increase t little by little.
