A 2D terrain model for the globe.
<p>
<a class="el" href="a00635.html" title="A 2D terrain model for the globe.">vtkGeoTerrain2D</a> contains a multi-resolution tree of geometry representing the globe. It uses a <a class="el" href="a00633.html" title="A multi-resolution geographic data source.">vtkGeoSource</a> subclass to generate the terrain, such as <a class="el" href="a00630.html" title="A 2D geographic geometry source.">vtkGeoProjectionSource</a>. This source must be set before using the terrain in a <a class="el" href="a00640.html" title="A 2D geospatial view.">vtkGeoView2D</a>. The terrain also contains an <a class="el" href="a00634.html#f1eb48daad7ec420afa45aa8561f95b1">AddActors()</a> method which updates the set of actors representing the globe given the current camera position.<p>
