Creating a Point Emitter

The first thing we will discover is how to make a Point Emitter, which is an object that generates Points for each frame, just like the Particle System built into Blender. We can make this happen by the use of the Distribute Points on Faces node.

The idea is that we want to repeat this Distribute Points on Faces node each frame while also moving the old Points down; this will create the effect of a Point Emitter.

Let’s take a look at the steps we’ll have to take to achieve this:

1. Let’s start this demo with a new node tree added to a Plane in our Viewport.
2. Let’s also add a Simulation Zone and connect it accordingly. To make this Plane emit Points, the first thing we have to do is drop in a Distribute Points on Faces node before the Simulation Zone nodes.
3. Next, we want to add Points to our Viewport as each frame progresses. We can do that using a Join Geometry node in our Simulation Zone. Let’s...
