Created by Peder Norrby of Trapcode, Vortex.A is his personal experiment with fluid dynamics: how liquids and gases behave – a classically difficult problem in physics/maths. Instead of adopting the available solutions for specific cases, Peder has been trying out his own approach and as a result making some pretty promising animations. The app visualizes the flow by emitting particles where you touch the screen (multi-touch works) and the fluid itself is also affected by touch. The lines are so called “pathlines” that trace the particles’ paths over time.
He will also be bringing it to VFX/motion graphics artists as a tool for fluid dynamics animations in the future. For those unaware, Peder is the author of the very popular Trapcode Suite plugins for Adobe After Effects, seen in many movies such as Terminator Salvation, Angels and Demons, Sin City, Spider Man 3, Quantum of Solace and more..
