Exploring Mesh nodes
Let’s start by explaining the nodes you’ll need the most, the Mesh nodes. These are used to modify the mesh you are working with. In this chapter, we will go over the most basic nodes you are likely to use with any Geometry Nodes project.
The Subdivision Surface node
We are all familiar with the Subdivision Surface modifier.
Figure 2.1: Subdivision Surface node
To easily explain this node, we will be comparing it to the modifier. The input node called Mesh refers to the mesh you give the node to process. The Level integer value refers to the iterations of subdivision, just as the modifier offers.
The next values you’ll see on the node aren’t values we see on the modifier. These are creasing values. These define how much the mesh should be affected by the Subdivision Surface modifier. As you can see by the square node connection shape, the node has a multivalued field. That means that this node can...
