Rendering a Model Rendering a Model The RENDER command creates a realistic image of a model, Figure 1-16. However, rendering an image takes longer than shading an image. There are a variety of settings that you can use to fi ne-tune renderings. These include lights, materials, backgrounds, and rendering preferences. AutoCAD provides six rendering presets, the highest of which can require up to 12 hours to perform. Render settings are discussed in detail in Chapters 16 through 19. When the RENDER command is initiated, the Render window is displayed and the image is rendered. See Figure 1-17. If the Render window closes, use the RENDERWINDOW command to redisplay the window. The rendering that is produced is based on a variety of render settings that are discussed in Chapters 16 through 19. If no lights have been created in the scene, AutoCAD uses default lighting to generate the rendering. The AutoCAD default lighting consists of one or two distant light sources that evenly illuminate all surfaces and generate shadows. If no materials have been applied to objects in the scene, objects are rendered with a matte material that is the same color as the object display color. NOTE NOTE If the image is rendered in the viewport, clean the screen using the ZOOM or PAN command. Setting the rendering destination as the viewport is discussed in Chapter 19.
