Three points

A0 [0,0]; A1 [1,2]; A3 [3,3]

are interpolated by algebraic polynom and result equation is: 

p2 = A0*X^2 + A1*X + A0;

Is there a way how to calculate [X,Y] of point in interval from <0, 1>?

I'm simply trying to reconstruct object trajectory based on leading points (A0, A1, A2.

Do you not simply want

p2[0] = A0[0]*X^2 + A1[0]*X + A2[0]
p2[1] = A0[1]*X^2 + A1[1]*X + A2[1]
thus spake a.k.

  • I think not. The <0,1> is beginning and end of the trajectory, so if you want move object along the trajectory for ex. into half you just set input parameter to 0.5 – user2977027 Jun 24 '14 at 07:21
