Distributing the points on a Grid primitive

The first topic we will be covering in this chapter is distributing points onto a Grid Primitive. These steps can also be applied to any other mesh. This step is crucial to instance objects in the Geometry Node editor.

Exploring the nodes we will be using

To get started with this demonstration, we will have to think about what we want to achieve. In this case, we want to distribute points onto a grid. To do this, we will need a total of three nodes, the Grid node primitive, the Distribute Points on Faces node, and the Join Geometry node.

Figure 5.1: The different nodes you’ll need

Let’s start by explaining what these three nodes will do in this demonstration:

  • The Grid node: This will be the base input, the mesh that we will get started within the Geometry Node editor, in this case, a Grid primitive.
  • The Distribute Points on Faces node: This node will, as the title of this node...
