Create a Reveal Effect in Blender Geometry Nodes using Linear Falloff

This tutorial is using Blender 2.93.0 Beta

Although Geometry Nodes does not support simulation yet, we can still use it to create effects that look like particles. In this tutorial you'll learn how to implement a linear falloff using the dot product to control a lot of instances procedurally, We'll then use the weight created by the falloff to alter scaling and location of the instances, to create some interesting behaviour. Warping the input space by using a 3D noise then makes everything more organic.
