public class MouseGetVirtualLocation
extends com.sun.j3d.utils.behaviors.mouse.MouseBehavior

This class finds the virtual location of a mouse on the canvas. Takes into account how far the canvas has been zoomed. Use this to create dynamic axis or mouse location indicators in Java3D components.

Method Detail

setCanvas3D

public void setCanvas3D(javax.media.j3d.Canvas3D canvas)

setAspectRatioPolicy

public void setAspectRatioPolicy(boolean aspectRatio)

initialize

public void initialize()

Overrides:

initialize in class com.sun.j3d.utils.behaviors.mouse.MouseBehavior

processStimulus

public void processStimulus(java.util.Enumeration criteria)

Specified by:

processStimulus in class com.sun.j3d.utils.behaviors.mouse.MouseBehavior

getRealLoc

public javax.vecmath.Point3d getRealLoc(java.awt.Point p1)

Converts a pixel point on the screen to a real world co-ordinate, taking into account zoom and translation effects. Use this as a communication link between 2D and 3D java components Be aware of aspect ratio. Make sure to set this mouse listener to aspect ration=true if any scale operations are performed on the corresponding transform group.

Parameters:

p1 -

Returns:

converttoxyMeters
