<p>In <a href="Scientific_visualization" title="Scientific visualization">scientific visualization</a>, <b>image-based flow visualization</b> (or <b>visualisation</b>) is a computer modelling technique developed by <a href="Jarke_van_Wijk" class="mw-redirect" title="Jarke van Wijk">Jarke van Wijk</a><sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> to visualize two dimensional flows of liquids such as water and air, like the wind movement of a <a href="Tornado" title="Tornado">tornado</a>. 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 <a href="Texture_advection" title="Texture advection">texture advection</a> family.

<p>The core idea is to create a noise texture on a regular grid and then bend this grid according to the flow (the vector field). The bent grid is then sampled at the original grid locations. Thus, the output is a version of the noise, that is displaced according to the flow.

</p><p>The advantage of this approach is that it can be accelerated on modern graphics hardware, thus allowing for <a href="Real-time_simulation" title="Real-time simulation">real-time</a> or almost real-time simulation of 2D flow data. This is particularly handy if one wants to visualise multiple scaled versions of the vector field to first gain an overview and then concentrate on the details.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
