Package javax.media.j3d
Class ScaleInterpolator
- java.lang.Object
-
public class ScaleInterpolator extends TransformInterpolator
Scale interpolation behavior. This class defines a behavior that modifies the uniform scale component of its target TransformGroup by linearly interpolating between a pair of specified scale values (using the value generated by the specified Alpha object). The interpolated scale value is used to generate a scale transform in the local coordinate system of this interpolator.

Constructor Summary
Constructors Constructor Description ScaleInterpolator(Alpha alpha, TransformGroup target)
Constructs a trivial scale interpolator that varies its target TransformGroup node between the two specified alpha values using the specified alpha, an identity matrix, a minimum scale = 0.1f, and a maximum scale = 1.0f.ScaleInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float minimumScale, float maximumScale)
Constructs a new scaleInterpolator object that varies its target TransformGroup node's scale component between two scale values (minimumScale and maximumScale).

ScaleInterpolator
public ScaleInterpolator(Alpha alpha, TransformGroup target)
Constructs a trivial scale interpolator that varies its target TransformGroup node between the two specified alpha values using the specified alpha, an identity matrix, a minimum scale = 0.1f, and a maximum scale = 1.0f.- Parameters:
alpha
- the alpha object for this interpolatortarget
- the TransformGroup node affected by this interpolator
-
ScaleInterpolator
public ScaleInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float minimumScale, float maximumScale)
Constructs a new scaleInterpolator object that varies its target TransformGroup node's scale component between two scale values (minimumScale and maximumScale).- Parameters:
alpha
- the alpha object for this interpolatortarget
- the TransformGroup node affected by this interpolatoraxisOfTransform
- the transform that defines the local coordinate system in which this interpolator operates; the scale is done about the origin of this local coordinate system.minimumScale
- the starting scalemaximumScale
- the ending scale
-

Method Detail
-
setMinimumScale
public void setMinimumScale(float scale)
This method sets the minimumScale for this interpolator.- Parameters:
scale
- The new minimal scale
-
getMinimumScale
public float getMinimumScale()
This method retrieves this interpolator's minimumScale.- Returns:
- the interpolator's minimal scale value
-
setMaximumScale
public void setMaximumScale(float scale)
This method sets the maximumScale for this interpolator.- Parameters:
scale
- the new maximum scale
-
getMaximumScale
public float getMaximumScale()
This method retrieves this interpolator's maximumScale.- Returns:
- the interpolator's maximum scale vslue
-
setAxisOfScale
public void setAxisOfScale(Transform3D axisOfScale)
Deprecated.As of Java 3D version 1.3, replaced byTransformInterpolator.setTransformAxis(Transform3D)
-
getAxisOfScale
public Transform3D getAxisOfScale()
Deprecated.As of Java 3D version 1.3, replaced byTransformInterpolator.getTransformAxis()
-
computeTransform
public void computeTransform(float alphaValue, Transform3D transform)
Computes the new transform for this interpolator for a given alpha value.- Specified by:
computeTransform
in classTransformInterpolator
- Parameters:
alphaValue
- alpha value between 0.0 and 1.0transform
- object that receives the computed transform for the specified alpha value- Since:
- Java 3D 1.3
-
cloneNode
public Node cloneNode(boolean forceDuplicate)
Used to create a new instance of the node. This routine is called bycloneTree
to duplicate the current node.- Overrides:
cloneNode
in classNode
- Parameters:
forceDuplicate
- when set totrue
, causes theduplicateOnCloneTree
flag to be ignored. Whenfalse
, the value of each node'sduplicateOnCloneTree
variable determines whether NodeComponent data is duplicated or copied.- See Also:
Node.cloneTree()
,Node.cloneNode(boolean)
,Node.duplicateNode(javax.media.j3d.Node, boolean)
,NodeComponent.setDuplicateOnCloneTree(boolean)
