Creating and Adjusting Texture Maps

You’ve already seen how you can assign a material to an object by adding the granite pebbles and glass materials to the buildings in the Facade3. dwgfile. Many of these materials make use of bitmap image files to simulate textures. You can create your own surface textures or use bitmaps in other ways to help enhance your rendering. For…

3D Rendering in AutoCAD

Just a few years ago it took the power of a workstation to create the kind of images you will create in this chapter. Today you can render not just a single image but several hundred images to build computer animations. And with the explosion of game software the Internet and virtual reality real-time walk-through sessions of 3D computer…

Adding Landscape and People

There’s nothing like adding landscaping and people to a rendering to adda sense of life and scale. Computer images, in particular, need landscape props because they tend to appear cold and somewhat lifeless. AutoCAD offers a set of pre-built landscape objects to help soften the appearance of your rendering. Let’s see how you can add a few trees and…
