<div class="textblock"><p><a class="el" href="classMercator_1_1Shader.html" title="Base class for Shader objects which create surface data for use when rendering terrain.">Shader</a> agregating surface data. </p>
<p>Some applications require the terrain surface data be stored in a single buffer so specific locations can be queried to determine the type. Typically this is used on a server, where lots of surface data optimised for rendering is not required, but fast cheap queries about the surface at a specific point are required. </p>
