All Implemented Interfaces:

Cloneable, Serializable

public class TransformGroup

extends Group

implements Serializable, Cloneable

This class represents a trasformationGroup. A transformationGroup includes a transformation matrix witch transforms all children. So it's possible to move (translate), rotate and scale them. You can move relatively (truetranslate()) or absolutely (setPosition()). Title : Earth Copyright : Copyright (c) 2001 Organisation : IGD FhG

Overrides:

getType in class Group

Returns:

type (always TYPE_Group)

getSubType

public int getSubType()

Returns SUBTYPE_TransformGroup. Defined in ModelGraphObject

Overrides:

getSubType in class Group

Returns:

SUBTYPE_TransformGroup

setTransformation

public boolean setTransformation(cMatrix4d tfm)

Sets the transformation matrix (blocked by mutable).

Parameters:

tfm - transformation matrix

Returns:

true on success

getTransformation

public cMatrix4d getTransformation()

Returns a transformation matrix clone.

Returns:

transformation matrix (clone)

translate

public boolean translate(double x,
                         double y,
                         double z)

Returns:

true on success

scale

public boolean scale(double s)

Scales the matrix with the given value (mul) (blocked by mutable).

Parameters:

s - Scale

Returns:

true on success

setPosition

Overrides:

allowChildAddEvent in class Group

Parameters:

n - Node to check

Returns:

true if it's allowed to add this node (always true)

clone

public Object clone()
