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.
