Converting a mesh to a wireframe

First up is the method to convert a mesh to a wireframe, which we have already used in this book. For example, we used it when we wanted to make the tesseract cube in Chapter 6, Working with the Spreadsheet.

Let’s repeat the basics one more time. The idea is that we want to take a mesh and disregard all the faces from it. This is the first step in making a wireframe effect.

Luckily, this can be done using the Mesh to Curve node, which disregards all the faces in its received input.

After that, we can use a Curve to Mesh node to convert these curves back to a mesh.

Don’t forget to utilize the Profile Curve socket; otherwise, your node will not work as intended.

Usually, you’ll use a Curve Circle node as your profile curve. It’s best to use a low-resolution Curve Circle node, since the shape of it will be used in the wires of your wireframe mesh. It’s also good to use a low radius so that your model does...
