3D textures
~~~~~~~~~~~

3D textures can be applied to objects defined by a heightmap, that can be generated
either as a regular greyscale image, or from a 3D scene defined using signed distance
functions.

In both cases, the **Apply** node is used to define 3D coordinates to query 3D textures,
and the **Select** node can be used to apply different 3D textures depending on a color
index.
