Understanding the Geometry Node editor
The Geometry Nodes system makes use of the node tree design in Blender, similar to the Material Node editor. Much like the Material Node editor, the node system flows from left to right. Geometry Nodes can modify and create different types of geometry, such as the following:
- Meshes: A mesh is a structural build of a 3D model consisting of faces. 3D meshes make use of the three axis points, x, y, and z. It is made up of vertices, which make up edges, which, in turn, make up faces.
- Curves: A curve is a way to define paths in Blender; this can be used on multiple occasions. For example, if you want a camera to follow a specific path, this can be done with curves. These can also be modified, used, and created in the Geometry Node editor. Curves will be further explained in Chapter 8.
- Point clouds: A point cloud is a selection of scattered points around a mesh. These point clouds are only visible in the viewport and not in the render.
- Volumes: A volume...
