Package Vrml2Sourcebook.Chapter09SensingViewer

package Vrml2Sourcebook.Chapter09SensingViewer

Authors can design interactivity into a scene that responds to user actions.

A scene can sense when the viewer's cursor is over a shape, has touched a shape, or is dragging atop a shape. A scene can also trigger animations on a viewer's touch, enabling the viewer to move and rotate shapes. There are four main action sensor types: TouchSensor senses touch, SphereSensor senses drags in a spherical way, CylinderSensor senses drags cylindrically, and PlaneSensor senses drags around a plane.

These X3D scenes are adapted directly from the original VRML 2.0 Sourcebook chapter examples. Also available: Introduction to VRML97 SIGGRAPH98 course notes.

This X3D VRML2 Sourcebook Chapter 09 Sensing Viewer examples archive is online.

The X3D Java Scene Access Interface (x3djsail) package provides concrete classes for each X3D node and statement.
