Rendering "fills in" geometry with color, shadow, lighting

effects, and so on.

Rendering shades the scene’s geometry using the

lighting you ’ve set up, the materials you’ve applied,

and environment settings, such as background

and atmosphere. You use the

Render Scene dialog

(page 3–2)

to create renderings and save them to

files. Renderings are also displayed on the screen,

in a

rendered fr ame window (page 3–5)

Tip: When you render a very large image, you might

get a message that says “Error Creating Bitmap,”

or that says you are out of RAM. If this happens,

turn on the Bitmap Pager. You turn on the Bitmap

Pager in

Rendering Preferences (page 3–863)

.The

Bitmap Pager prevents a rendering from hanging

because of overuse of memory. On the other hand ,

it slows down the rendering process.

Environments and R endering Effects

A variety of specia l effects, such as film g rain,

depth of field, and lens simulations, are a vailable

as rendering effects. Another set of effects, such as

fog, are provided as environment effects.

Environment settings (page 3–268)

let you choose

a background color or image, or choose an

ambient color value for when you render without

using radiosity. One category of environment

settings is the

exposure controls (page 3–289)

which adjust light levels for display on a monitor.

Rendering effects (page 3 –214)
