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.
