HS-236: Velocity Forces 2.0: Advanced Information

Students will walk away with a more complete understanding of volumes in Houdini, advanced VEX computations, and how to utilize powerful native nodes to generate more intricate motion in their simulations.

Class Description:

“Velocity Forces 2.0: Advanced” is an in-depth class expanding on “Velocity Forces 1.0”. It delves deeper into creating velocity fields, exploring the differences between Houdini Standard Volumes and OpenVDB volumes.

The course focuses on techniques to help you refine velocity fields, blend multiple fields together, and use alternative simulation outputs for unique movement. You’ll learn how to create vorticles, enhance simulations with wake turbulence forces, as well as injecting extra detailed motion into low-resolution smoke sims. Additionally, this class will cover volume optical flow fields on both 2D planar and 3D geometry, plus utilizing the Potential Flow node for 3D surface advection.

This class will also show how to move beyond volume-based fields into dynamic VEX coding, reducing the volume caching overhead, while also tackling advanced mathematical concepts, from matrices and quaternions to cross products and vector math.
