Introduction to node primitives

Node primitives allow you to place primitive shapes into your scenes by using various nodes.

However, firstly, what are primitives?

Primitives are shapes that are relatively simple in terms of geometry or can be calculated using a mathematical equation. In Blender, these objects include a grid, a cube, a cylinder, and two different types of spheres.

Curves also have various primitives. These include a line, a circle, a star, a spiral, and a Bezier curve.

Node primitives are really easy to use. Each node primitive will likely convert a bunch of parameters into a single mesh/curve object that will be outputted as a geometry output node socket.

However, why should we use node primitives? They are really useful because we can change the properties of these shapes while working in the Node editor. It’s a matter of changing a value or slider to change the shape of the primitive.
