Line Integral Convolution

I’ve been doing research on line integral convolution visualization techniques via texture advection. These are interesting techniques to visualize vector fields. The resulting visualizations are very similar to this physics experiment that uses iron “sand” to visualize a magnetic dipole vector field:

These same techniques can be applied to visualize flows. Here’s an example.

If you’d like to know more about this project you can access a related blog post here.

The papers implemented are:

• Imaging Vector Fields Using Line Integral Convolution by Brian Cabral Leith (Casey) Leedom
• Animating Flowfields: Rendering of Oriented Line Integral Convolution
• Lagrangian-Eulerian Advection of Noise and Dye Textures for Unsteady Flow Visualization by Bruno Jobard, Gordon Erlebacher, and M. Yousuff Hussaini.
