+3D signed distance function geometry nodes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The signed distance function nodes can be used to define complex 3D 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 heightmap and a color normal map using the **render** node.
+
+Describing 3D objects using SDF primitives is more difficult than using existing meshes, but this
+method integrates smoothly with shader generation, and (as many nodes in Material Maker) is
+resolution independant.
+
+All output samples shown in this section are preview images.
+
+All Signed Distance Functions nodes are based on code written by Inigo Quilez that can be found
+`on this page`__.
