smoothing

Update 6 : Fenomenas suggested me to re-create everything as simple as possible. I had my doubts that this would make any difference as the algorithm remains the same, and performance did not seem to be the issue. Anyway, it was the only suggestion I got so here it is: 30 FPS: http://www.feedpostal.com/test/simple/30/SimpleMovement.html 40 FPS: http://www.feedpostal.com/test/simple/40/SimpleMovement.html 60 FPS: http://www.feedpostal.com/test/simple/60/SimpleMovement.html 100 FPS: http://www.feedpostal.com/test/simple/100/SimpleMovement.html The code: package { import flash.display.Sprite;

I have datapoints f(x_i) at points x_i (function f not known, only numerically) with f(0) = 0. The data show a peaklike structure at small x, to be followed by a slow shoulder-falloff at larger x that sets in half-way down from the maximum. I want to plot smoothed lines through these data points. If I use bezier then indeed f(0)=0 is ok, but the peak is significantly (by about 25%), lowered. If I use acsplines then the peak looks somewhat better, but f(0) = 0 is not maintained. How can I smooth that dataset without loosing vital info (f(0)=0) or the peak-height of the distribution? Smoothing

I'm trying to write a method that interpolates from 0 to x (position of an object in one dimension) over time using acceleration at the beginning and deceleration at the end (ease out / ease in) with the only constraints that the total time is provided , as well as the duration of the acceleration and deceleration . the motion should replicate the inertia effect and I'm considering a Hermite curve for the non-linear portions. double Interpolate( double timeToAccel, double timeCruising, double timeToDecel, double finalPosition, double currentTime) { //... } Can someone point me out to a portion

So far none of the threads here on smooth lines are correct. how to draw smooth curve through N points using javascript HTML5 canvas? Smooth user drawn lines in canvas Both result in jagged lines. By smooth I mean using the x,y points as control points to make the line smooth. The line does NOT need to go through the points. It simply has to draw a smooth line given n points. Basically I'm recording each line segment, then when the user mouses up, it wil smooth the line. I've tried my own method using bezierCurveTo but that only smooths every other point, and then the connecting points are

I've got a program that allows users to draw curves. But these curves don't look nice - they look wobbly and hand-drawn. So I want an algorithm that will automatically smooth them. I know there are inherent ambiguities in the smoothing process, so it won't be perfect every time, but such algorithms do seem to exist in several drawing packages and they work quite well. Are there any code samples for something like this? C# would be perfect, but I can translate from other languages. You can reduce the number of points using the Ramer–Douglas–Peucker algorithm there is a C# implementation here .

I have a 3D sensor which measures v(x,y,z) data. I'm only using the x and y data. Smoothing only x and y would be enough. If I use a log to show the data, it shows me something like this: (time) 0.1 ... (Data log) x = 1.1234566667 (time) 0.2 ... (Data log) x = 1.1245655666 (time) 0.3 ... (data log) x = 1.2344445555 Well the data is more exact actually, but I want to smooth between the 1.1234 value and the 1.2344 value, because for me it's the same, I can use integers to, showing only "x= 1" but I need the decimals too, then, I need to show a sort of "smoothed" value here. Anyone has any idea?
