realistic.
To enhance a scene’s realism by having lights
cast shadows.
All kinds of lig hts can cast shadows. Also, you
can selectively control w hether an object casts
or receives shadows. See
Shadow Parameters
(page 2–1181)
.
To cast projections in a scene.
All kinds of lights can project st ill or animated
maps. See the Projector Map group in the
Advanced Effects rollout (page 2–1185)

scene, such as a flashlight.
Lig ht objects don’t render, so to model a
source of illumination, you also need to create
geometry that corresponds to the light source.
Use a
self-illuminating (page 3–1103)
material
to make the geometry appear as if it’s emitting
light.
To create lig hting scenes using manufacturers

You can visualize commercially available
lighting in your model by creating
photometric
lights (page 2–1155)
based on manufacturer’s
photometric data files. By experimenting
w ith different fixtures, and varying the light
intensity and color temperature, you can

Wor k ing with Lights
The procedures in this topic apply to both standard
and photometric lights.
Here are some general tips about working with
lights:
One simple way to light a scene is to conver t the
default lighting into light objects by using the
command
Add Default Lights To Scene (page
1–49)
.
Note: Add Default Lights To Scene works only
if you have used the
Viewport Configuration
dialog (page 3–896)
