Voxyde explores methods to generate particles from an animated mesh in Side FX Houdini.

Voxyde (Ciobanu Razvan) posts a free chapter from his course that covers Geometry Based Simulations with Houdini, and Nuke. This free dive offers some insights into generating particles from an animated mesh in Houdini.

Voxyde shows how to drive the particles by rising the xyzDist Function and then controls the direction of the particles by way of vector operations, in this case, a cross product. The tutorial also shows how to make the particles stick to the geometry surface and update them automatically to match the animation.
