| RotationPathInterpolator | | public class RotationPathInterpolator extends PathInterpolator (Code) | | RotationPathInterpolator behavior. This class defines a behavior
that varies the rotational component of its target TransformGroup
by linearly interpolating among a series of predefined knot/orientation
pairs (using the value generated by the specified Alpha object). The
interpolated orientation is used to generate a rotation transform in
the local coordinate system. The first knot must have a value of 0.0.
The last knot must have a value
of 1.0. An intermediate knot with index k must have a value strictly
greater than any knot with index less than k.

| Method Summary | |
| public Node | cloneNode(boolean forceDuplicate)
Used to create a new instance of the node. | | public void | computeTransform(float alphaValue, Transform3D transform)
Computes the new transform for this interpolator for a given
alpha value. | | void | duplicateAttributes(Node originalNode, boolean forceDuplicate)
Copies all RotationPathInterpolator information from
originalNode into
the current node. | | public Transform3D | getAxisOfRotation()
| | public void | getQuat(int index, Quat4f quat)
Retrieves the quat value at the specified index. | | public void | getQuats(Quat4f[] quats)
Copies the array of quaternion values from this interpolator
into the specified array. | | public void | setAxisOfRotation(Transform3D axisOfRotation)
| | public void | setPathArrays(float[] knots, Quat4f[] quats)
Replaces the existing arrays of knot values and quaternion
values with the specified arrays. | | public void | setQuat(int index, Quat4f quat)
Sets the quat value at the specified index for this
interpolator. |
| RotationPathInterpolator | | RotationPathInterpolator()(Code) | | |
| RotationPathInterpolator | | public RotationPathInterpolator(Alpha alpha, TransformGroup target, Transform3D axisOfTransform, float[] knots, Quat4f[] quats)(Code) | | Constructs a new RotationPathInterpolator object that varies the
target TransformGroup node's transform.
Parameters:
alpha - the alpha object of this interpolator
Parameters:
target - the TransformGroup node affected by this interpolator
Parameters:
axisOfTransform - the transform that defines the local coordinatesystem in which this interpolator operates
Parameters:
knots - an array of knot values that specify interpolation points
Parameters:
quats - an array of quaternion values at the knots
exception:
IllegalArgumentException - if the lengths of theknots and quats arrays are not the same. |
| cloneNode | | public Node cloneNode(boolean forceDuplicate)(Code) | | Used to create a new instance of the node. This routine is called
by cloneTree to duplicate the current node.
Parameters:
forceDuplicate - when set to true, causes theduplicateOnCloneTree flag to be ignored. Whenfalse, the value of each node'sduplicateOnCloneTree variable determines whetherNodeComponent data is duplicated or copied.

| computeTransform | | public void computeTransform(float alphaValue, Transform3D transform)(Code) | | Computes the new transform for this interpolator for a given
alpha value.
Parameters:
alphaValue - alpha value between 0.0 and 1.0
Parameters:
transform - object that receives the computed transform forthe specified alpha value

Java 3D 1.3 |
| duplicateAttributes | | void duplicateAttributes(Node originalNode, boolean forceDuplicate)(Code) | | Copies all RotationPathInterpolator information from
originalNode into
the current node. This method is called from the
cloneNode method which is, in turn, called by the
cloneTree method.
Parameters:
originalNode - the original node to duplicate.
Parameters:
forceDuplicate - when set to true, causes theduplicateOnCloneTree flag to be ignored. Whenfalse, the value of each node'sduplicateOnCloneTree variable determines whetherNodeComponent data is duplicated or copied.
exception:
RestrictedAccessException - if this object is part of a liveor compiled scenegraph.

| getQuat | | public void getQuat(int index, Quat4f quat)(Code) | | Retrieves the quat value at the specified index.
Parameters:
index - the index of the value requested
Parameters:
quat - the quat object that will have thequat value at index copied into it. |
| getQuats | | public void getQuats(Quat4f[] quats)(Code) | | Copies the array of quaternion values from this interpolator
into the specified array.
The array must be large enough to hold all of the quats.
The individual array elements must be allocated by the caller.
Parameters:
quats - array that will receive the quats
since:
Java 3D 1.2 |
| setPathArrays | | public void setPathArrays(float[] knots, Quat4f[] quats)(Code) | | Replaces the existing arrays of knot values and quaternion
values with the specified arrays.
The arrays of knots and quats are copied
into this interpolator object.
Parameters:
knots - a new array of knot values that specifyinterpolation points
Parameters:
quats - a new array of quaternion values at the knots
exception:
IllegalArgumentException - if the lengths of theknots and quats arrays are not the same.
since:

| setQuat | | public void setQuat(int index, Quat4f quat)(Code) | | Sets the quat value at the specified index for this
interpolator.
Parameters:
index - the index to be changed
Parameters:
quat - the new quat value at the index |
