Chapter 19 Advanced Rendering 515 Copyright Goodheart-Willcox Co., Inc. PROFESSIONAL TIP PROFESSIONAL TIP The Low, Medium, and High render presets provide very nice quality renderings in a short period of time. The Coffee-Break Quality, Lunch Quality, and Overnight Quality presets, because of their default settings, sometimes produce worse results than the quicker rendering methods. You will need to experiment with settings on your own computer to determine what works best for your scene. Render Settings The Render Presets Manager palette is used to control basic render settings. See Figure 19-3. The RPREF command opens the palette. The palette can also be displayed by picking the dialog box launcher button at the lower-right corner of the Render panel on the Visualize tab of the ribbon. The settings in this palette are discussed in the following sections. Output Settings The settings at the top of the Render Presets Manager palette specify the location where AutoCAD processes the rendering and the output size of the rendered image. The same settings are available in the Render panel on the Visualize tab of the ribbon. Picking the Render button at the top-right corner of the palette renders the scene with the current settings. There are three settings in the Render in: drop-down list. The Window setting renders the scene in the Render window. This is the default setting. The Viewport setting renders the scene directly to the viewport. Because the area of the rendering will most likely be larger, expect the rendering to take longer to process. However, it will be easier to see the details of the rendered scene. Zooming or panning will cause the rendering to disappear. You can use the SAVEIMG command to save the rendered image to an image fi le. However, the quality of the result is dependent on the resolution of the monitor, which may produce a low-resolution image. The Region setting also renders the scene directly to the viewport. When using this setting, you are prompted to pick two points defi ning a rectangular region to render. AutoCAD only processes the objects in this region. This is an excellent way to quickly perform a test rendering and check on lighting, materials, and shadows.
