| ExamineViewerBehavior | | public class ExamineViewerBehavior extends ViewerBehavior (Code) | | Wakeup on mouse button presses, releases, and mouse movements and
generate transforms in an "examination style" that enables the user
to rotate, translation, and zoom an object as if it is held at
arm's length. Such an examination style is similar to the "Examine"
navigation type used by VRML browsers.
The behavior maps mouse drags to different transforms depending
upon the mosue button held down:
Button 1 (left)
Horizontal movement --> Y-axis rotation
Vertical movement --> X-axis rotation
Button 2 (middle)
Horizontal movement --> nothing
Vertical movement --> Z-axis translation
Button 3 (right)
Horizontal movement --> X-axis translation
Vertical movement --> Y-axis translation
To support systems with 2 or 1 mouse buttons, the following
alternate mappings are supported while dragging with any mouse
button held down and zero or more keyboard modifiers held down:
No modifiers = Button 1
ALT = Button 2
Meta = Button 3
Control = Button 3
The behavior automatically modifies a TransformGroup provided
to the constructor. The TransformGroup's transform can be set
at any time by the application or other behaviors to cause the
examine rotation and translation to be reset.

Construct an examine behavior that listens to mouse movement
and button presses to generate rotation and translation
transforms written into the given transform group. | | public | ExamineViewerBehavior(TransformGroup transformGroup, Component parent)
Construct an examine behavior that listens to mouse movement
and button presses to generate rotation and translation
transforms written into the given transform group. |
