Constructor Summary

TranslationManipulator()

Method Summary

void	clearSelection() Clears current selection of objects to be translated.
boolean	getCheckClipPlanes() Returns flag that indicates if the translated object will be kept in the area between the two clipping planes during translation or if it will be allowed to go astray.
void	setBeginPoint(int x, int y) Sets mouse location where manipulation started.
void	setCanvas3D(javax.media.j3d.Canvas3D canvas) Sets the Canvas3D from which manipulations are performed.
void	setCheckClipPlanes(boolean checkClipPlanes) Sets flag used to determine if the translated object must be kept between the two clipping planes or no check should be performed to assure that condition.

public TranslationManipulator()

Method Detail

setTranslatableObject

public void setTranslatableObject(TranslatableObject translatableObject)

setCanvas3D

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

Sets the Canvas3D from which manipulations are performed.

Overrides:

setCanvas3D in class TransformationManipulator

Parameters:

canvas - Canvas3D object that originates manipulations.

setBeginPoint

public void setBeginPoint(int x,
                          int y)

Sets mouse location where manipulation started.

Overrides:

setBeginPoint in class TransformationManipulator

Parameters:

x - x coordinate of manipulation's initial point.

y - y coordinate of manipulation's initial point.

setCheckClipPlanes

public void setCheckClipPlanes(boolean checkClipPlanes)

Sets flag used to determine if the translated object must be kept between the two clipping planes or no check should be performed to assure that condition.
The checking process will only be performed if the view that is shown by the Canvas3D has both the back and front clip policies set to View.VIRTUAL_EYE

Parameters:

checkClipPlanes - if true, the translated object will be kept in the area between the two clipping planes; if false that condition is not assured.

getCheckClipPlanes

public boolean getCheckClipPlanes()

Returns flag that indicates if the translated object will be kept in the area between the two clipping planes during translation or if it will be allowed to go astray.

clearSelection

public void clearSelection()

Clears current selection of objects to be translated.

Specified by:

clearSelection in class TransformationManipulator

setCurrentPoint

public void setCurrentPoint(int x,
                            int y)

Sets current mouse location during manipulation.

Overrides:

setCurrentPoint in class TransformationManipulator

Parameters:

x - x coordinate of current manipulation point.

y - y coordinate of current manipulation point.
