VRML97 Helper Objects

The VRML97 helpers let you create online 3D scenes and interaction using Virtual Reality Markup Language. Insert a VRML 97 Helper into the scene by clicking and dragging at the desired location.

Create panel > Helpers > VRML97 > Object Type rollout

Note: Some helper objects (for example, Billboard and Level Of Detail) are position-sensitive, so be careful how and where you insert them. Usually, you have the most control by creating the helper object in the Top viewport.

Topics in this section

Anchor VRML97 Helper
The Anchor helper lets you specify a click-to-play trigger in the scene. This trigger will be linked to a currently existing object in the scene. This allows you to add links to other HTML pages, VRML97 worlds, or alternate cameras in your VRML97 world.
ProxSensor VRML97 Helper
The ProxSensor helper creates a VRML97 ProximitySensor node. This lets you set up a rectangular region in space, so that entering the region in a VRML97 browser starts a set of objects animating.
NavInfo VRML97 Helper
The NavInfo helper lets you create a VRML97 NavigationInfo node. This tells the browser how to navigate around the VRML97 world.
Fog VRML97 Helper
The Fog helper lets you specify the color and range of fog in your VRML97 world. You can simulate atmospheric effects by blending objects with a color based on the objects' distances from the viewer. For the best visual results, the background (which is unaffected by the fog) should be the same color as the fog.
Sound VRML97 Helper
The Sound helper lets you place 3D (spatial) or ambient sounds in a scene.
LOD VRML97 Helper
The Level of Detail (LOD) helper lets you specify objects with varying face counts that are appropriate for different viewing distances. Browsers display the less detailed objects when the viewer is far away from them and substitute the more detailed objects at closer ranges.
TouchSensor VRML97 Helper
The TouchSensor helper lets you set up an object so that selecting it in a VRML97 browser starts a set of objects animating.
TimeSensor VRML97 Helper
The TimeSensor helper lets you add time-based animation controls, such as the start and end frames for a particular object's animation, and looping. Use this helper to split up an object's animation keys over several triggers, to automatically start an animation upon loading the .wrl file, or to make animation endlessly loop.
Background VRML97 Helper
The Background helper has Sky Color, Ground Color, and Images rollouts. Use these rollouts to specify colors and images for the sky and ground in your VRML97 world.
AudioClip VRML97 Helper
The AudioClip helper lets you specify the name and characteristics of an audio file that can be used by the Sound helper.
Billboard VRML97 Helper
The Billboard helper lets you create geometry that is camera-aligned in the VRML97 browser. The objects always align to the viewpoint in the VRML97 browser.
Inline VRML97 Helper
The Inline helper lets you reference another VRML97 file that is included in your world when you load it into your VRML97 browser. These inline objects are like instance objects, but they function at the browser level.
