# TP Geometry

> **Note:** **What is it about?**
>
> This page documents the **TP Geometry object** in **Cinema 4D**. It makes Thinking Particles visible and renderable by generating their geometry in the scene — required in addition to the XPresso setup, and usable as input for deformers.

The TP Geometry object must be present in the scene if geometry should be shown/rendered for the particles. Simply linking an [PObjectShape Node](https://help.maxon.net/c4d/en-us/Content/html/OP_OBJECTSHAPE.html.md) in the XPresso Expressions is not enough. The TP Geometry object is a Generator that can, for example also be used to affect a [Deformation objects](https://help.maxon.net/c4d/en-us/Content/html/5460.html.md).
