• ColorInterpolator

  public ColorInterpolator(Alpha alpha,
                           Material target)

  Constructs a trivial color interpolator with a specified target, a starting color of black, and an ending color of white.

  Parameters:

  alpha - the alpha object for this interpolator

  target - the material component object whose color is affected by this color interpolator

• ColorInterpolator

  public ColorInterpolator(Alpha alpha,
                           Material target,
                           Color3f startColor,
                           Color3f endColor)

  Constructs a color interpolator with the specified target, starting color, and ending color.

  Parameters:

  alpha - the alpha object for this interpolator

  target - the material component object whose color is affected by this color interpolator

  startColor - the starting color

  endColor - the ending color

Method Detail

• setStartColor

  public void setStartColor(Color3f color)

  This method sets the startColor for this interpolator.

  Parameters:

  color - the new start color

• getStartColor

  public void getStartColor(Color3f color)

  This method retrieves this interpolator's startColor.

  Parameters:

  color - the vector that will receive the interpolator's start color

• setEndColor

  public void setEndColor(Color3f color)

  This method sets the endColor for this interpolator.

  Parameters:

  color - the new end color

• getEndColor

  public void getEndColor(Color3f color)

  This method retrieves this interpolator's endColor.

  Parameters:

  color - the vector that will receive the interpolator's end color

• setTarget

  public void setTarget(Material target)

  This method sets the target material component object for this interpolator.

  Parameters:

  target - the material component object whose color is affected by this color interpolator

• getTarget

  public Material getTarget()

  This method retrieves this interpolator's target material component object.

  Returns:

  the interpolator's target material component object

• processStimulus

  public void processStimulus(Enumeration criteria)

  This method is invoked by the behavior scheduler every frame. It maps the alpha value that corresponds to the current time into a color value and updates the ambient, emissive, diffuse, or specular color (or both the ambient and diffuse color) of the specified target Material object with this new color value.

  Specified by:

  processStimulus in class Behavior

  Parameters:

  criteria - an enumeration of the criteria that caused the stimulus

• cloneNode

  public Node cloneNode(boolean forceDuplicate)

  Used to create a new instance of the node. This routine is called by cloneTree to duplicate the current node.

  Overrides:

  cloneNode in class Node

  Parameters:

  forceDuplicate - when set to true, causes the duplicateOnCloneTree flag to be ignored. When false, the value of each node's duplicateOnCloneTree variable determines whether NodeComponent data is duplicated or copied.

• updateNodeReferences

  public void updateNodeReferences(NodeReferenceTable referenceTable)

  Callback used to allow a node to check if any scene graph objects referenced by that node have been duplicated via a call to cloneTree. This method is called by cloneTree after all nodes in the sub-graph have been duplicated. The cloned Leaf node's method will be called and the Leaf node can then look up any object references by using the getNewObjectReference method found in the NodeReferenceTable object. If a match is found, a reference to the corresponding object in the newly cloned sub-graph is returned. If no corresponding reference is found, either a DanglingReferenceException is thrown or a reference to the original object is returned depending on the value of the allowDanglingReferences parameter passed in the cloneTree call.

  NOTE: Applications should not call this method directly. It should only be called by the cloneTree method.

  Overrides:

  updateNodeReferences in class Behavior

  Parameters:

  referenceTable - a NodeReferenceTableObject that contains the getNewObjectReference method needed to search for new object instances.

  NodeReferenceTable, Node.cloneTree(), DanglingReferenceException
