These terrain parameters are contained in the class <a class="el" href="classTParams.html">TParams</a>.<p>To create a new terrain, first construct a vtTerrain and set its parameters with <a class="el" href="classvtTerrain.html#88daaa175c8c2b354978e0644d406318">SetParams()</a> or <a class="el" href="classvtTerrain.html#b95e711b4043712f2dbdda768847c281">SetParamFile()</a>. You can also set many properties of the terrain directly, which is useful if you want to set them from memory instead of from disk. These include:<ul><li>Elevation grid: use <a class="el" href="classvtTerrain.html#0e25e0149c2ea9db5ffd1ff346042e5f">SetLocalGrid()</a>.</li><li>Elevation TIN: use <a class="el" href="classvtTerrain.html#714df531fa3dc046e8df0d176ee19f52">SetTin()</a>.</li><li>Structures: use <a class="el" href="classvtTerrain.html#bcfa4a28c19f3969d1b6a4776d4574f9">NewStructureLayer()</a>, then fill it with your structures.</li><li>Vegetation: call <a class="el" href="classvtTerrain.html#784e617a1d5d6cab0987f34afb736f16">SetPlantList()</a>, then <a class="el" href="classvtTerrain.html#9caafe29e804ad33c163b3fd2c3763fa">GetPlantInstances()</a>.</li><li>Abstract layers: use GetAbstractLayers(), then create and append your <a class="el" href="classvtAbstractLayer.html">vtAbstractLayer</a> objects. The features will be created according to the properties you have set with vtFeatureSet::SetProperties(). The properties you can set are documented with the class <a class="el" href="classTParams.html">TParams</a>.</li><li>Animation paths: use <a class="el" href="classvtTerrain.html#ca2f45ded7cb88774e2152cbd4d45150">GetAnimContainer()</a>, then add your own animpaths.</li></ul><p>You can then build the terrain using the CreateStep methods, or add it to a <a class="el" href="classvtTerrainScene.html">vtTerrainScene</a> and use <a class="el" href="classvtTerrainScene.html#318b0789336bfc9fcd2e6509735dd4b4">vtTerrainScene::BuildTerrain</a>.<p><h3>Customizing your Terrain</h3><p>To extend your terrain beyond what is possible with the terrain parameters, you can create a subclass of vtTerrain and implement the method <a class="el" href="classvtTerrain.html#d22c8350e93364fade9737ad21bf0d4e">CreateCustomCulture()</a>. Here you can create anything you like, and add it to the terrain. Generally you should add your nodes with <a class="el" href="classvtTerrain.html#9e283572e63cbdcf612e81538408d25e">AddNode()</a>, or <a class="el" href="classvtTerrain.html#485af80e54e56904d87fabab897b8f45">AddNodeToStructGrid()</a> if it is a structure that should be culled in the distance. You can also add your nodes with <a class="el" href="classvtTerrain.html#c29baa6f32a8886f56eb7370f05ef4d6">GetScaledFeatures()</a>->AddChild(), if they are 'flat' like GIS features or contour lines, which should be scaled up/down with the vertical exaggeration of the terrain. <p><table border="0" cellpadding="0" cellspacing="0"><tr><td></td></tr><tr><td colspan="2"><br><h2>Public Member
