public class PjEventCamera

extends PjProject

implements PvCameraListenerIf

Demo project showing how to handle camera events issued from a JavaView display. In this example the events are used to steer the camera in a second window.

The camera events from one window are used to steer the camera in the other window such that a stereo effect is produced. Note, the viewing direction of the left camera is slightly rotated around the up-vector of the camera by about 6 degrees.

Constructor Detail

PjEventCamera

public PjEventCamera()

Method Detail

init

public void init()

Description copied from class: PjProject

Initialize and reset project, stops the running animation if any. Does not reset any registered display nor geometry. They must be reset individually in each subclass.

Overrides:

init in class PjProject

start

public void start()

Description copied from class: PjProject

Method is invoked during loading of a project in JavaView.

If a project has an animation object, then the animation panel is shown when the project's this start() method is invoked during loading of the project. Use setAnimation(PsAnimation) to register an animation.

If auto fit is enabled then scenery is scaled to fit in each display.

Overrides:

start in class PjProject

Following copied from class: jv.project.PjProject

PvViewerIf.start(), #isEnabledAutoFit(boolean)

getRightDisplay

public PvDisplayIf getRightDisplay()

getLeftDisplay

public PvDisplayIf getLeftDisplay()

pickCamera

public void pickCamera(PvCameraEvent pos)

Get camera events resulting from picking the mouse. Use information about camera in one display to adjust the camera in the other window. But previously rotate the camera position around the line given by interest+t*upVector by -6 degrees.

Specified by:

pickCamera in interface PvCameraListenerIf

Following copied from interface: jv.project.PvCameraListenerIf

Parameters:

event - Pick event issued by the display

See Also:

PvCameraListenerIf

dragCamera

public void dragCamera(PvCameraEvent pos)

Get camera events resulting from dragging the mouse. This method just calls the method pickCamera which does all the work.

Specified by:

dragCamera in interface PvCameraListenerIf

Following copied from interface: jv.project.PvCameraListenerIf

Parameters:

event - Drag event issued by the display
