David Torno – HS-204: Forces: Building Custom Velocity Setups

Students should leave with a better understanding of how to begin building and implementing their own velocity flows for art directing simulations.

Class Description:

This recorded class will explain how to shape vectors into custom velocity fields for use in art directing particles, objects, liquids, and volumes movement. Moving data through different contexts in Houdini is a must-know in creating stellar FX, and controlling that movement even more so. You will learn how to create and control velocity field forces in Houdini and through the power of VEX coding, I will guide you through the core basics of vectors, forces, and velocities. VEX can be a highly technical subject to discuss, but the aim of this class is to make it as easily understandable for artistic and technical minds alike. Each bit of code will be fully explained and questions are highly encouraged.
