# Closest Point on Surface

> **Note:** **What is it about?**
>
> This page covers the **Closest Point on Surface node** of the Scene Nodes system in **Cinema 4D**. It finds the surface positions nearest to a 3D coordinate — the basis for snapping, projections and contact effects.

This Node calculates those positions on the surface of the connected geometry that are closest to a defined 3D coordinate.
