Linear interpolation of two vector arrays with different lenghts I have two curves. One handdrawn and one is a smoothed version of the handdrawn. The data of each curve is stored in 2 seperate vector arrays. Time Delta is also stored in the handdrawn curve vector, so i can replay the drawing process and so that it looks natural. Now i need to transfer the Time Delta from Curve 1 (Raw input) to Curve 2 (the already smoothed curve). Sometimes the size of the first vector is larger and sometimes smaller than the second vector. (Depends on the input draw speed) So my question is: How do i fill the whole vector PenSmoot.time with the correct interpolated values? Case 1: Input vector is larger PenInput.time[0] = 0 PenSmoot.time[0] = 0 PenInput.time[1] = 5 PenSmoot.time[1] = ? PenInput.time[2] = 12 PenSmoot.time[2] = ? PenInput.time[3] = 2 PenSmoot.time[3] = ? PenInput.time[4] = 50 PenSmoot.time[4] = ? PenInput.time[5] = 100 PenInput.time[6] = 20 PenInput.time[7] = 3 PenInput.time[8] = 9 PenInput.time[9] = 33 Case 2: Input vector is smaller PenInput.time[0] = 0 PenSmoot.time[0] = 0 PenInput.time[1] = 5 PenSmoot.time[1] = ? PenInput.time[2] = 12 PenSmoot.time[2] = ? PenInput.time[3] = 2 PenSmoot.time[3] = ? PenInput.time[4] = 50 PenSmoot.time[4] = ? PenSmoot.time[5] = ? PenSmoot.time[6] = ? PenSmoot.time[7] = ? PenSmoot.time[8] = ? PenSmoot.time[9] = ? https://ift.tt/eA8V8J
