This tutorial shows a technique for doing procedural text animation in Houdini, which I covered in my Motion Graphics class at SideFX software in October. Thanks to Peter Claes who provided guidance on the letter attribute problem.
Andrew D Lyons presents a solution to the problem of how to create a large number of moving contained fluids. This presentation was originally given to the San Francisco Houdini User's Group which was held at PIXAR studios in October 2010.
The final system demonstrates how Houdini's unique procedural tools can be used to create automated solutions to VFX challenges that might otherwise require costly dynamic simulations. The system draws on a number of Houdini's operator contexts in order to do so.
