<hr><a name="_details"></a><h2>Detailed Description</h2>
Terrain cell class.
<p>
Terrain consists of cells, each cell has its own coordinate system (2-axis position and 3-axis scaling). All operations (loading, preloading, destroying, construction of inner structures for rendering, etc.) are done at cell level.<p>
A cell can be created via <a class="el" href="structiTerrainFactory.html" title="Provides an interface for creating terrain system.">iTerrainFactory</a> interface.
