		+	'''Node Description and Purpose:'''<br />
		+	The Displacement shader takes the values generated by the connected function nodes and turns them into displacement. You can connect any sort of function nodes to the input but the input value is converted to a scalar.
		+
		+
		+	'''Node Type:''' Displacement Shader<br />

		+	'''Settings:'''
		+	<ul>
		+	<li>
		+	'''Function:''' You connect the function node(s) which generate the displacement values to this input.
		+	</li><li>
		+	'''Displacement direction:''' This popup list allows you to choose the direction that displacement is applied in. Any options in the popup list that have "(requires computed normal)" require that there be a [[Compute Terrain]] or [[Compute Normal]] connected somewhere above the node in the network to work properly. The popup has the following options:
		+	<ul>
		+	<li>
		+	<u>Along vertical:</u> Displacement will happen along the normal of the underlying object (i.e. the planet or a model) without any displacement being applied.
		+	</li><li>
		+	<u>Along normal:</u> Displacement will happen along the current surface normal.

		+	<u>Vertical only (requires computed normal):</u> Displacement only happens along the normal of the underlying object (i.e. the planet or a model). The displacement is scaled by the difference between the object normal and the surface normal. Displacement is reduced as the angle between the normals approaches 90°.

		+	<u>Lateral only (requires computed normal):</u> Displacement only occurs in the lateral plane, or in other words perpendicular to the normal of the underlying object.
		+	</li><li>
		+	<u>Lateral normalized (requires computed normal):</u> This is the same as <u>Lateral only</u> but the normal is normalised (scaled so it has a length of 1).
