Particle Choreography
Lesson 3 of 4 Houdini Particles
Now that we know the basics, let’s learn the finer points of particle simulation: control. In this lesson we’ll learn how to control timing, influence direction and flow, and learn more elaborate ways of directing our particle systems.

Assignment
Pick one (or both of the following)
Using POPS, create a procedural rain system, with small splashes, trails, and dripping effects. Focus on the state changes necessary to create this complex system.
Using POPS and SOPS, create a sparks system that detects collisions between objects and outputs a variety of sparks from those collision locations. Final output should be renderable lines (or curves). Extra points for accounting for curved motion blur to get truly believable sparks.
Extra Credit
Create a shape-morphing simulation. The sim should move between 3 different shapes of animated objects. The motion should smoothly ease in and out of each morph state, and show a gradual morph, rather than the entire object morphing at the same frame.

Lesson 1
Time-Based Solvers
Before getting into Houdini’s POPs particle network, we’re going to learn what’s happening under the hood by building several of our own time-based solvers from scratch. This will provide a great fundamental understanding of simulation environments, data, and how to add your own functionality to built-in Houdini solvers.- 2 hours 15 minutesTotal Lesson Duration

Lesson 2
Intro to Particles
We’re going to dive into Houdini’s POP network and learn the basics of particle simulations. Here, you’ll become familiar with the core components of our dynamics system, including emitters, forces, colliders, and more. We’ll then use these skills to take into the next lesson to create more advanced systems.- 2 hours 42 minutesTotal Lesson Duration

Particle Rendering
What do we do with all of these points we’ve worked so hard to choreograph? In this lesson, we’re going to explore the many ways to render particles, and we’ll look at tip and tricks to create some interesting effects through rendering with Mantra.- 2 hours 10 minutesTotal Lesson Duration
