# 2D Signed distance function geometry nodes

The signed distance function nodes can be used to define complex geometry using simple shapes.

They are based on a very small set of basic shapes, that can be combined using operators, and finally output as a greyscale image using the sdShow node.

All output samples shown in this section are images generated through the sdShow node.

All Signed Distance Functions nodes are based on code written by Inigo Quilez that can be found on this page.
