If you wish to use your own drawing and image files, skip to the next section. If you do not have any AutoCAD contours and a corresponding bitmap or if you wish to follow this tutorial closely, you may like to download the sample files before you continue. The tutotial also covers the rendering of such objects. This tutorial will show you how to import contours (created using AutoCAD) into 3D Studio, how to use the contours to create a terrain object, how to apply colour by elevation and how to map a bitmap image onto the terrain surface. Surprisingly, rendered terrains of this sort are relatively easy to create. You could even map an aerial photograph onto a terrain object to create a realistic representation of the real world. The illustrations on the right show a terrain object rendered with the object colour (top), with "Colour by Elevation" (middle) and with a mapped bitmap image (bottom). Such terrain objects can then be rendered in a number of ways. 3D Studio VIZ R2 has an excellent but simple terrain modeller that can create accurate, triangulated surfaces and solids. If you want to create a good visualisation of a terrain model, AutoCAD is not the best tool for the job. However, such terrain models are mainly used for the more technical aspects of terrain modelling such as cut-and-fill, visual impact analysis etc. It is even possible to create more complex objects such as terrain models with the aid of additional software such as Key TERRA-FIRMA. AutoCAD is an excellent tool for basic visualisations of relatively simple objects.
