Adding Special Objects to a Scene
You can add a number of special objects to your scene:
-
Lights
-
Spot lights, point lights, and directional lights can add exciting
visual effects to a scene.
-
Sounds
-
The added realism of crickets chirping, water splashing, and pipes
clanking can enhance your scene too.
-
Links
-
Click on a link to an HTML document or enter a new VRML world.
-
Billboards
-
Billboards are objects that rotate around a specified axis and always
face the viewer. They're a useful optimization technique.
-
Collision Detection Groupings
-
You can turn off collision detection or provide a proxy (substitute
object) for testing collisions. Collision detection groupings are also
useful for optimization.
-
Navigation Info Objects
-
You can include objects that store information about the scene, such as
the initial viewer type, whether to turn on a headlight, the size of
the avatar, and the height of objects over which it can step.
