# Cissoid

> **Note:** **What is it about?**
>
> This page describes the **Cissoid node primitive** of the Scene Nodes system in **Cinema 4D**. It generates the cissoid family of mathematical curves as splines — distinctive shapes for profiles and ornaments.

Creates various mathematical curves as spline geometry.
