Dissolving text with force mapping

Dissolving text, meshes and other objects into particles. Static particle bodies and displacement forces first, then text that erodes into blowing 3D leaf sprites under wind and vortex.

Wave emitters, formulas and paths

Building a flowing wave with the formula emitter: mixing and summing wave shapes, giving the spline volume and flattening it into a ribbon, then stacking child systems so geometry rides the path, tracers draw tubes behind it, and sprites drift along with inherited velocity.

Designing with modulators

Modulators, tracers and nested systems: driving a system with a form that is itself moving, drawing the paths particles take, and letting a system feed children of its own.
