Using Models: adding 3DS models to Landscapes
In this tutorial we're going to look at rendering 3D models inside GenesisIV Landscapes. GenesisIV can use models in the popular 3DS format, which are rendered inside directly inside the landscape. GenesisIV is ideal for exploring the addition of buildings and other structures to landscapes - Pylons, Wind Generators and Communication masts are common examples, but complex settlements can be built up.


This tutorial uses the same model of Uluru (or Ayres Rock) used for the terrain tutorial, although we'll generally be rendering at a fractal level of 4 or greater to obtain a more photorealistic effect.

Our first image shows the basic landscape, into which we will place our models.

 

 
 
Two new model layers are created. The first, shown right, will hold 3DS models of a fir tree.

GenesisIV can of course use 2D image and 3D lsystem vegetation, but using 3DS models works well where a small number of trees are required and complements the more broad-brush effect of general forestry.		  
The watertower is a simple 3DS model.  

Although models can be placed on the surface using the Heightfield Editor, the quickest way to place individual models in is directly in the main screen. Highlight the model layer in the layers list, then click anywhere on the 2D map to place a new model for that layer. The model is shown as a colored dot.

You can select models already placed by selecting their terrain layer and clicking on the dot. Right clicking a selected model brings up a context menu where you can delete the model or edit it's properties.

Placed models are shown in the 3D screen once the movement controls have been clicked.

  
 
Rerendering shows our Uluru from the same vantage point as before, but with our new watertower and screening trees. We've purposly made this model rather large to demonstrate the effects.
