Hi Maxim! Are you capturing the points on line objects, or on a bitmap drawn at the bottom that has to be interpolated and redrawn on every mouse movement? Try separating the capture and paint areas, capturing line objects instead of pixels on a bitmap, or at least draw the bitmap with the lowest posible interpolation quality, to see if it helps.
Hope it works :) On Thu, Oct 6, 2016 at 5:49 AM, Maxim Solodovnik <solomax...@gmail.com> wrote: > changing FPS to 60 doesn't help :( (originally it was 30) > Final code for capturing events and drawing is the same as prototype code > still got ugly, non-smooth curve in case mouse moving very fast > > Line in much smoother in Gimp > In fact Flex desktop app produces smooth enough line > will try to create browser quick start and double check > > On Thu, Oct 6, 2016 at 9:18 AM, Maxim Solodovnik <solomax...@gmail.com> > wrote: > > Hello, > > > > Thanks a lot for the quick answers, definitely flex is one of my > > favorite communities :) > > Here is example project: https://github.com/solomax/FlexSandbox > > since it is desktop and tiny it looks not that bad > > In my main project the resulting line is not smooth at all :( > > > > I'll try to check the code and remove any delays, thanks for the pointer. > > > > Additionally I'll try to check FFT, I have tried to add additional > > points and use cubicCurveTo, but was unable to finish this (it is > > currently commented) > > > > On Thu, Oct 6, 2016 at 1:47 AM, OK <p...@olafkrueger.net> wrote: > >> Alex Harui wrote > >>>>can't you just up the frame per second of the swf to say 60, and if > >>>>needed interpolate data points to smooth it? > >>> That is a possibility, but the interpolation code may also affect input > >>> rate. > >> > >> For this approach it might be helpful to google with "spline > interpolation" > >> and "FFT" (Fast Fourier Transformation).
