# Spline Emitter

> **Note:** **What is it about?**
>
> This page documents the **Spline Emitter** of the particle system in **Cinema 4D**. It emits particles from spline points, sections or a tube-shaped surrounding — making curves the direct source of streams, trails and outline effects.

This Emitter is closely related to the *Mesh Emitter*, except that the particles here do not originate from the points, areas or the volume of a polygon geometry, but from an assigned spline geometry. The particles can occur at the points of the spline, in its tubular surroundings or only at individual sections of the curve.
