In [[scientific visualization]], '''image-based flow visualization''' (or '''visualisation''') is a computer modelling technique developed by [[Jarke van Wijk]]<ref>{{cite journal|last=van Wijk|first=Jack|authorlink=Jack van Wijk|title=Image Based Flow Visualization|journal=Proceedings ACM SIGGRAPH 2002, San Antonio, Texas|year=2002|url=http://www.win.tue.nl/~vanwijk/ibfv/ibfv.pdf}}</ref> to visualize two dimensional flows of liquids such as water and air, like the wind movement of a [[tornado]]. Compared with integration techniques it has the advantage of producing a whole image at every step, as the technique relies upon graphical computing methods for frame-by-frame capture of the model of advective transport of a decaying dye. It is a method from the [[texture advection]] family.
